public AbstractByteFloatMap copy()
clone() and casts the result.

This implementation first checks if the specified object is this map; if so it returns true. Then, it
checks if the specified object is a map whose size is identical to the size of this set; if not, it it returns
false. If so, it applies the iteration as described above.
equals in class Objectobj - object to be compared for equality with this map.
public int hashCode()
hashCode in class Objectpublic abstract boolean forEachKey(ByteProcedure procedure)
procedure - the procedure to be applied. Stops iteration if the procedure returns false, otherwise
continues.
public boolean forEachPair(ByteFloatProcedure procedure)
forEachKey(ByteProcedure).
procedure - the procedure to be applied. Stops iteration if the procedure returns false, otherwise
continues.
public abstract float get(byte key)
containsKey(byte) whether the given key has a value associated or not, i.e. whether there exists an association
for the given key or not.
key - the key to be searched for.
public ByteArrayList keys()
forEachKey(ByteProcedure). This method can be used to iterate over the keys of the receiver.
public void keys(ByteArrayList list)
forEachKey(ByteProcedure). This method can be used to iterate over the keys of the receiver.
list - the list to be filled, can have any size.public void keysSortedByValue(ByteArrayList keyList)
Example:
keys = (8,7,6), values = (1,2,2) --> keyList =
(8,6,7)
keyList - the list to be filled, can have any size.
public void pairsMatching(ByteFloatProcedure condition,
ByteArrayList keyList,
FloatArrayList valueList)
forEachKey(ByteProcedure).
Example:
IntIntProcedure condition = new IntIntProcedure() { // match even keys only
public boolean apply(int key, int value) { return key%2==0; }
}
keys = (8,7,6), values = (1,2,2) --> keyList = (6,8), valueList = (2,1)
condition - the condition to be matched. Takes the current key as first and the current value as second
argument.keyList - the list to be filled with keys, can have any size.valueList - the list to be filled with values, can have any size.
public void pairsSortedByKey(ByteArrayList keyList,
FloatArrayList valueList)
Example:
keys = (8,7,6), values = (1,2,2) --> keyList = (6,7,8), valueList = (2,2,1)

public void pairsSortedByValue(ByteArrayList keyList,
FloatArrayList valueList)
Example:
keys = (8,7,6), values = (1,2,2) --> keyList = (8,6,7),
valueList = (1,2,2)
keyList - the list to be filled with keys, can have any size.valueList - the list to be filled with values, can have any size.
