Overrides:

reset in class Map

getLongestMatch

protected java.lang.Object getLongestMatch(BitSet key_)

Description copied from class: Map

Returns the longest match.

Overrides:

getLongestMatch in class Map

Parameters:

key_ - the key to match.

Returns:

the entry with the key matching the argument with largest number of bits.

getExactMatch

protected java.lang.Object getExactMatch(MapKey key_)

Description copied from class: Map

Returns the exact match.

Overrides:

getExactMatch in class Map

Parameters:

key_ - the key to match.

Returns:

the entry with the key exactly matching the argument.

removeLongestMatch

protected java.lang.Object removeLongestMatch(BitSet key_)
