Method Detail

defaultValue

byte defaultValue()

Returns the default value of this map, which is used instead of null in primitive specialization methods, when the key is absent in the map.

Returns:: the default value of this map
See Also:: LongByteMapFactory.withDefaultValue(byte)

containsKey

@Deprecated
boolean containsKey(Object key)

Deprecated. Use specialization containsKey(long) instead

Returns true if this map contains a mapping for the specified key. More formally, returns true if and only if this map contains a mapping for a key k such that (key==null ? k==null : key.equals(k)). (There can be at most one such mapping.)

Specified by:: containsKey in interface Map<Long,Byte>

Parameters:: key - key whose presence in this map is to be tested
Returns:: true if this map contains a mapping for the specified key

containsKey

boolean containsKey(long key)

Returns true if this map contains a mapping for the specified key.

Parameters:: key - the long key whose presence in this map is to be tested
Returns:: true if this map contains a mapping for the specified key

containsValue

@Deprecated
boolean containsValue(Object value)

Deprecated. Use specialization containsValue(byte) instead

Returns true if this map maps one or more keys to the specified value. More formally, returns true if and only if this map contains at least one mapping to a value v such that (value==null ? v==null : value.equals(v)). This operation will probably require time linear in the map size for most implementations of the Map interface.

Specified by:: containsValue in interface Map<Long,Byte>

Parameters:: value - value whose presence in this map is to be tested
Returns:: true if this map maps one or more keys to the specified value

containsValue

boolean containsValue(byte value)

Returns true if this map maps one or more keys to the specified value. This operation will probably require time linear in the map size for most implementations of the LongByteMap interface.

Parameters:: value - the byte value whose presence in this map is to be tested
Returns:: true if this map maps one or more keys to the specified value

get

@Nullable
@Deprecated
Byte get(Object key)

Deprecated. Use specialization get(long) instead

Returns the value to which the specified key is mapped, or null if this map contains no mapping for the key.

More formally, if this map contains a mapping from a key k to a value v such that (key==null ? k==null : key.equals(k)), then this method returns v; otherwise it returns null. (There can be at most one such mapping.)

If this map permits null values, then a return value of null does not necessarily indicate that the map contains no mapping for the key; it's also possible that the map explicitly maps the key to null. The containsKey operation may be used to distinguish these two cases.

Specified by:: get in interface Map<Long,Byte>

Parameters:: key - the key whose associated value is to be returned
Returns:: the value to which the specified key is mapped, or null if this map contains no mapping for the key

get

byte get(long key)

Returns the value to which the specified key is mapped, or default value if this map contains no mapping for the key.

Parameters:: key - the key whose associated value is to be returned
Returns:: the value to which the specified key is mapped, or default value if this map contains no mapping for the key

getOrDefault

@Deprecated
Byte getOrDefault(Object key,
                             Byte defaultValue)

Deprecated. Use specialization getOrDefault(long, byte) instead

Returns the value to which the specified key is mapped, or defaultValue if this map contains no mapping for the key.

Parameters:: key - the key whose associated value is to be returned; defaultValue - the default mapping of the key
Returns:: the value to which the specified key is mapped, or defaultValue if this map contains no mapping for the key

getOrDefault

byte getOrDefault(long key,
                  byte defaultValue)

Returns the value to which the specified key is mapped, or defaultValue if this map contains no mapping for the key.

Parameters:: key - the key whose associated value is to be returned; defaultValue - the value to return if the specified key is absent in the map
Returns:: the value to which the specified key is mapped, or defaultValue if this map contains no mapping for the key

forEach

void forEach(@Nonnull
             LongByteConsumer action)

Performs the given action on each entry in this map until all entries have been processed or the action throws an Exception. Exceptions thrown by the action are relayed to the caller. The entries will be processed in the same order as the entry set iterator unless that order is unspecified in which case implementations may use an order which differs from the entry set iterator.

Parameters:: action - The action to be performed for each entry
See Also:: Comparison of iteration options in the library

forEachWhile

boolean forEachWhile(@Nonnull
                     LongBytePredicate predicate)

Checks the given predicate on each entry in this map until all entries have been processed or the predicate returns false for some entry, or throws an Exception. Exceptions thrown by the predicate are relayed to the caller.

The entries will be processed in the same order as the entry set iterator unless that order is unspecified in which case implementations may use an order which differs from the entry set iterator.

If the map is empty, this method returns true immediately.

Parameters:: predicate - the predicate to be checked for each entry
Returns:: true if the predicate returned true for all entries of the map, false if it returned false for the entry
See Also:: Comparison of iteration options in the library

cursor

@Nonnull
LongByteCursor cursor()

Returns a new cursor over the entries of this map. It's order is always correspond to the entry set iterator order.

Basic cursor usage idiom is:

for (LongByteCursor cur = map.cursor(); cur.moveNext();) {
     // Work with cur.key() and cur.value()
     // Call cur.remove() to remove the current entry
 }

Returns:: a new cursor over the entries of this map
See Also:: Comparison of iteration options in the library

keySet

@Nonnull
LongSet keySet()

Description copied from interface: java.util.Map

Returns a Set view of the keys contained in this map. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an iteration over the set is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Set.remove, removeAll, retainAll, and clear operations. It does not support the add or addAll operations.

Specified by:: keySet in interface Map<Long,Byte>

Returns:: a set view of the keys contained in this map

values

@Nonnull
ByteCollection values()

Description copied from interface: java.util.Map

Returns a Collection view of the values contained in this map. The collection is backed by the map, so changes to the map are reflected in the collection, and vice-versa. If the map is modified while an iteration over the collection is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The collection supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Collection.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.

Specified by:: values in interface Map<Long,Byte>

Returns:: a collection view of the values contained in this map

entrySet

@Nonnull
ObjSet<Map.Entry<Long,Byte>> entrySet()

Description copied from interface: java.util.Map

Returns a Set view of the mappings contained in this map. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an iteration over the set is in progress (except through the iterator's own remove operation, or through the setValue operation on a map entry returned by the iterator) the results of the iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Set.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.

Specified by:: entrySet in interface Map<Long,Byte>

Returns:: a set view of the mappings contained in this map

put

@Deprecated
Byte put(Long key,
                    Byte value)

Deprecated. Use specialization put(long, byte) instead

Associates the specified value with the specified key in this map (optional operation). If the map previously contained a mapping for the key, the old value is replaced by the specified value. (A map m is said to contain a mapping for a key k if and only if m.containsKey(k) would return true.)

Specified by:: put in interface Map<Long,Byte>

Parameters:: key - key with which the specified value is to be associated; value - value to be associated with the specified key

put

byte put(long key,
         byte value)

Parameters:: key - key with which the specified value is to be associated; value - value to be associated with the specified key
Returns:: the previous value associated with key, or default value if there was no mapping for key. (A default value return can also indicate that the map previously associated default value with key.)

putIfAbsent

@Nullable
@Deprecated
Byte putIfAbsent(Long key,
                                     Byte value)

Deprecated. Use specialization putIfAbsent(long, byte) instead

Parameters:: key - key with which the specified value is to be associated; value - value to be associated with the specified key
Returns:: the previous value associated with the specified key, or null if there was no mapping for the key. (A null return can also indicate that the map previously associated null with the key, if the implementation supports null values.)
Throws:: UnsupportedOperationException - if the put operation is not supported by this map; ClassCastException - if the key or value is of an inappropriate type for this map; NullPointerException - if the specified key or value is null; IllegalArgumentException - if some property of the specified key or value prevents it from being stored in this map

putIfAbsent

byte putIfAbsent(long key,
                 byte value)

If the specified key is not already associated with a value, associates it with the given value and returns default value, else returns the current value.

Parameters:: key - key with which the specified value is to be associated; value - value to be associated with the specified key
Returns:: the previous value associated with the specified key, or default value if there was no mapping for the key. (A default value return can also indicate that the map previously associated default value with the key, if the implementation supports such values.)

             @Nonnull
             LongByteToByteFunction remappingFunction)

Attempts to compute a mapping for the specified key and its current mapped value (or default value if there is no current mapping).

                     @Nonnull
                     LongToByteFunction mappingFunction)

If the specified key is not already associated with a value, attempts to compute its value using the given mapping function and enters it into this map . The most common usage is to construct a new object serving as an initial mapped value or memoized result.

If the function itself throws an (unchecked) exception, the exception is rethrown, and no mapping is recorded.

Parameters:: key - key with which the specified value is to be associated; mappingFunction - the function to compute a value

If the specified key is not already associated with a value, associates it with the given value, otherwise, replaces the value with the results of the given remapping function. This method may be of use when combining multiple mapped values for a key.

If the remappingFunction itself throws an (unchecked) exception, the exception is rethrown, and the current mapping is left unchanged.

Parameters:: key - key with which the specified value is to be associated; value - the value to use if absent; remappingFunction - the function to recompute a value if present
Returns:: the new value associated with the specified key

remove

@Nullable
@Deprecated
Byte remove(Object key)

Deprecated. Use specialization remove(long) instead

Removes the mapping for a key from this map if it is present (optional operation). More formally, if this map contains a mapping from key k to value v such that (key==null ? k==null : key.equals(k)), that mapping is removed. (The map can contain at most one such mapping.)

Returns the value to which this map previously associated the key, or null if the map contained no mapping for the key.

If this map permits null values, then a return value of null does not necessarily indicate that the map contained no mapping for the key; it's also possible that the map explicitly mapped the key to null.

The map will not contain a mapping for the specified key once the call returns.

Specified by:: remove in interface Map<Long,Byte>

Parameters:: key - key whose mapping is to be removed from the map
Returns:: the previous value associated with key, or null if there was no mapping for key.

byte remove(long key)

Removes the mapping for a key from this map if it is present (optional operation).

Returns the value to which this map previously associated the key, or default value if the map contained no mapping for the key.

A return value of default value does not necessarily indicate that the map contained no mapping for the key; it's also possible that the map explicitly mapped the key to default value.

The map will not contain a mapping for the specified key once the call returns.

Parameters:: key - key whose mapping is to be removed from the map
Returns:: the previous value associated with key, or default value if there was no mapping for key
Throws:: UnsupportedOperationException - if the remove operation is not supported by this map
