Method Detail

getBOSToken

public CToken getBOSToken()

Gets a unique beginning-of-string CToken. The CToken returned by this method is freshly cloned and not an alias of any other CToken

Returns:

A beginning-of-string CToken

getEOSToken

public CToken getEOSToken()

Gets a unique end-of-string CToken. The CToken returned by this method is freshly cloned and not an alias of any other CToken

Returns:

An end-of-string CToken

getUnknownToken

public CToken getUnknownToken()

Gets a unique unknown-morpheme CToken. The CToken returned by this method is freshly cloned and not an alias of any other CToken

Returns:

A unknown-morpheme CToken

getCost

public int getCost(Node lNode2,
                   Node lNode,
                   Node rNode)

Retrieves the cost between three Nodes from the connection cost matrix

Parameters:

lNode2 - The first Node

lNode - The second Node

rNode - The third Node

Returns:

The connection cost

commonPrefixSearch

public CToken[] commonPrefixSearch(CharIterator iterator)

Searches for possible morphemes starting at the current position of a CharIterator. The iterator is advanced by the length of the longest matching morpheme

Parameters:

iterator - The iterator to search from

Returns:

The possible morphemes found
