C# Class Egothor.Stemmer.MultiTrie2

The MultiTrie is a Trie of Tries.

It stores words and their associated patch commands. The MultiTrie handles patch commands broken into their constituent parts, as a MultiTrie does, but the commands are delimited by the skip command.

Method	Description
Add ( string key, string cmd ) : void	Add an element to this structure consisting of the given key and patch command. This method will return without executing if the cmd parameter's length is 0.
Decompose ( string cmd ) : string[]	Break the given patch command into its constituent pieces. The pieces are delimited by NOOP commands.
GetFully ( string key ) : string	Return the element that is stored in a cell associated with the given key.
GetLastOnPath ( string key ) : string	Return the element that is stored as last on a path belonging to the given key.
MultiTrie2 ( IDataInput @is ) : Lucene.Net.Support	Constructor for the MultiTrie object.
MultiTrie2 ( bool forward ) : Lucene.Net.Support	Constructor for the MultiTrie2 object
Reduce ( Reduce by ) : Egothor.Stemmer.Trie	Remove empty rows from the given Trie and return the newly reduced Trie.
Store ( IDataOutput os ) : void	Write this data structure to the given output stream.
