```
    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.

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

    value - value to be associated with the specified key

    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.

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

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

```
    Adds the given value addition to the value associated with the specified key, or the given initialValue if this map contains no mapping for the key, and associates the resulting value with the key.
    This version of addValue(byte, double) method is useful if you want to accumulate values from the different initial value, than the default value of this map.

    key - the key to which value add the given value
    
    addition - the value addition

void replaceAll(@Nonnull
                ByteDoubleToDoubleFunction function)
```
    Replaces each entry's value with the result of invoking the given function on that entry, in the order entries are returned by an entry set iterator, until all entries have been processed or the function throws an exception.
    
    Parameters:
    
    function - the function to apply to each entry
    
    Throws:
    
    UnsupportedOperationException - if the set operation is not supported by this map's entry set iterator
    
    IllegalArgumentException - if some property of a replacement value prevents it from being stored in this map (optional restriction)
  - remove

    Deprecated. Use specialization remove(byte) instead
    
    Specified by:
    
    remove in interface Map<Byte,Double>
  - remove
```
double remove(byte 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
  - remove

```
    Deprecated. Use specialization remove(byte, double) instead
    
    Removes the entry for the specified key only if it is currently mapped to the specified value.
    
    Specified by:
    
    remove in interface Map<Byte,Double>
    
    Parameters:
    
    key - key with which the specified value is associated
    
    value - value expected to be associated with the specified key
    
    Returns:
    
    true if the value was removed
    
    Throws:
    
    NullPointerException - if the specified key or value is null
    
    UnsupportedOperationException - if the remove operation is not supported by this map
  - remove
```
boolean remove(byte key,
               double value)
```
    Removes the entry for the specified key only if it is currently mapped to the specified value.
    
    Parameters:
    
    key - key with which the specified value is associated
    
    value - value expected to be associated with the specified key
    
    Returns:
    
    true if the value was removed
    
    Throws:
    
    UnsupportedOperationException - if the remove operation is not supported by this map
  - removeIf
```
boolean removeIf(@Nonnull
                 ByteDoublePredicate filter)
```
    Removes all of the entries of this collection that satisfy the given predicate. Errors or runtime exceptions thrown during iteration or by the predicate are relayed to the caller.
    
    Parameters:
    
    filter - a predicate which returns true for elements to be removed
    
    Returns:
    
    true if any elements were removed
    
    Throws:
    
    NullPointerException - if the specified filter is null
    
    UnsupportedOperationException - if elements cannot be removed from this collection. Implementations may throw this exception if a matching element cannot be removed or if, in general, removal is not supported.
