Method Detail

put

boolean put(String s,
          V v)

Put and entry into the Trie

Parameters:

s - The key for the entry

v - The value of the entry

Returns:

True if the Trie had capacity to add the field.

put

boolean put(V v)

Put a value as both a key and a value.

Parameters:

v - The value and key

Returns:

True if the Trie had capacity to add the field.

remove

V remove(String s)

get

V get(String s)

Get and exact match from a String key

Parameters:

s - The key

get

V get(String s,
    int offset,
    int len)
