Method Detail

put

public void put(Object key,
                double value)

Associates the specified value with the specified key in this map. If the map previously contained a mapping for this key, the old value is replaced.

Parameters:

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,
                double quantity)

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.

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.

getDouble

public double getDouble(Object key,
                        double 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.

Returns:

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