key - key with which the specified value is to be associated.

value - value to be associated with the specified key.

inc

public void inc(Object key,
                long quantity)

Parameters:

key - key for which the specified value must be incremented.

quantity - the quantity to increment

inc

public void inc(Object key)

Incremente the value associated with the specified key. If this key did not exist, it is created and the value is set to '1'.

Parameters:

key - key for which the specified value must be incremented.

getLong

public long getLong(Object key,
                    long defaultValue)

Returns the value to which this map maps the specified key. Returns defaultValue if the map contains no mapping for this key.

Parameters:

key - key whose associated value is to be returned.

defaultValue - value to return if the map contains no mapping for this key.
