Method Detail

addScoreNodes

public void addScoreNodes(Object key,
                 ScoreNode[] nodes)

Adds scoreNodes to this map under the given key. If there already exists a mapping with the given key the scoreNodes are added to the existing mapping. The add operation works as follows:

• If the existing value for key is a ScoreNode[], then the value is turned into a List and the existing value as well as the new value are added to the List. Finally the List is uses as the new value for the mapping.
• If the existing value for key is a List the scoreNodes are simply added to the List.

Parameters:

key - the lookup key.

nodes - the score nodes.

getScoreNodes

public ScoreNode[][] getScoreNodes(Object key)

Returns an array of ScoreNode[] for the given key.

Parameters:

key - the key.

Returns:

an array of ScoreNode[] that match the given key or null if there is none.
