Method Details

putSingle

public void putSingle(K key,
 V value)

Associate key with the single value value. If other values are already associated with key then override them.

Parameters:

key - the key to associate value with

value - the value to add to the context

add

public void add(K key,
 V value)

Associate key with the single value value. If other values are already associated with key, then add value to them.

Parameters:

key - the key to associate value with

value - the value to add to the context

getFirst

public V getFirst(Object key)

Get the first value contained in the list of values associated with key.

Parameters:
