Method Detail

keyEquivalence

@Nonnull
Equivalence<K> keyEquivalence()

Returns the equivalence strategy for keys in this map. All methods in the Map interface which defined in terms of Object.equals(Object) equality of key objects (almost all methods, actually), are supposed to use this equivalence instead.

Returns:

the equivalence strategy for keys in this map

See Also:

HashObjShortMapFactory.withKeyEquivalence(com.koloboke.collect.Equivalence<? super K>)

defaultValue

short 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:

ObjShortMapFactory.withDefaultValue(short)

containsValue

@Deprecated
boolean containsValue(Object value)

Deprecated. Use specialization containsValue(short) instead

Specified by:

containsValue in interface Map<K,Short>

containsValue

boolean containsValue(short 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 ObjShortMap interface.

Parameters:

value - the short 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
Short get(Object key)

Deprecated. Use specialization getShort(Object) instead

Specified by:

get in interface Map<K,Short>

getShort

short getShort(Object key)

Returns the value to which the specified key is mapped, or default value 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 keyEquivalence() == null ? (key==null ? k==null : key.equals(k)) : keyEquivalence().nullableEquivalent(k, key), then this method returns v; otherwise it returns default value. (There can be at most one such mapping.)

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

Throws:

ClassCastException - if the key is of an inappropriate type for this map (optional restriction)

NullPointerException - if the specified key is null and this map does not permit null keys (optional restriction)

getOrDefault

@Deprecated
Short getOrDefault(Object key,
                                Short defaultValue)

Deprecated. Use specialization getOrDefault(Object, short) instead

Specified by:

getOrDefault in interface Map<K,Short>

getOrDefault

short getOrDefault(Object key,
                   short 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

Throws:

ClassCastException - if the key is of an inappropriate type for this map (optional restriction)

NullPointerException - if the specified key is null and this map does not permit null keys (optional restriction)

forEach

@Deprecated
void forEach(@Nonnull
                          BiConsumer<? super K,? super Short> action)

Deprecated. Use specialization forEach(ObjShortConsumer) instead

Specified by:

forEach in interface Map<K,Short>

forEach

void forEach(@Nonnull
             ObjShortConsumer<? super K> 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
                     ObjShortPredicate<? super K> 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
ObjShortCursor<K> 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 (ObjShortCursor<K> cur = map.cursor(); cur.moveNext();) {
     // Work with cur.key() and cur.value()
     // Call cur.remove() to remove the current entry
 }

Returns:

More formally, if this map contains a mapping from a key k to a value v such that keyEquivalence() == null ? (key==null ? k==null : key.equals(k)) : keyEquivalence().nullableEquivalent(k, key), 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 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.
