public boolean containsKey(char key)

public AbstractCharObjectMap<T> 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(CharProcedure procedure)
procedure - the procedure to be applied. Stops iteration if the procedure returns false, otherwise
continues.
public boolean forEachPair(CharObjectProcedure<T> procedure)
forEachKey(CharProcedure).
procedure - the procedure to be applied. Stops iteration if the procedure returns false, otherwise
continues.
public abstract T get(char key)
containsKey(char) 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 CharArrayList keys()
forEachKey(CharProcedure). This method can be used to iterate over the keys of the receiver.
public void keys(CharArrayList list)
forEachKey(CharProcedure). 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(CharArrayList 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(CharObjectProcedure<T> condition,
CharArrayList keyList,
List<T> valueList)
forEachKey(CharProcedure).
Example:
CharObjectProcedure condition = new CharObjectProcedure() { // match even keys only
public boolean apply(char key, Object 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(CharArrayList keyList,
List<T> valueList)
Example:
keys = (8,7,6), values = (1,2,2) --> keyList = (6,7,8), valueList = (2,2,1)
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 pairsSortedByValue(CharArrayList keyList,
List<T> 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.
public abstract boolean put(char key,
T value)
key - the key the value shall be associated with.value - the value to be associated.
