class |
CachingTokenFilter
This class can be used if the token attributes of a TokenStream
are intended to be consumed more than once.
|
class |
FilteringTokenFilter
Abstract base class for TokenFilters that may remove tokens.
|
class |
GraphTokenFilter
An abstract TokenFilter that exposes its input stream as a graph
Call
GraphTokenFilter.incrementBaseToken() to move the root of the graph to the next
position in the TokenStream, GraphTokenFilter.incrementGraphToken() to move along
the current graph, and GraphTokenFilter.incrementGraph() to reset to the next graph
based at the current root. |
class |
LowerCaseFilter
Normalizes token text to lower case.
|
class |
StopFilter
Removes stop words from a token stream.
|
class |
TokenFilter
A TokenFilter is a TokenStream whose input is another TokenStream.
|
class |
Tokenizer
A Tokenizer is a TokenStream whose input is a Reader.
