Method Detail

getTokens

public List getTokens()

Get the tokens in the internal List.

WARNING: Adding tokens to this list requires the reset() method to be called in order for them to be made available. Also, this Tokenizer does nothing to protect against ConcurrentModificationExceptions in the case of adds happening while TokenStream.next(org.apache.lucene.analysis.Token) is being called.

Returns:

A List of Tokens

next

public Token next()
           throws IOException

Returns the next token out of the list of cached tokens

Overrides:

next in class TokenStream

Returns:

The next Token in the Sink.

Throws:

IOException

add

public void add(Token t)

Override this method to cache only certain tokens, or new tokens based on the old tokens.

Parameters:

t - The Token to add to the sink

close

public void close()
           throws IOException

Description copied from class: Tokenizer

By default, closes the input Reader.

Overrides:

close in class Tokenizer

Throws:

IOException

reset

public void reset()
           throws IOException

Reset the internal data structures to the start at the front of the list of tokens. Should be called if tokens were added to the list after an invocation of TokenStream.next(Token)

Overrides:

reset in class TokenStream

Throws:

IOException
