C# 클래스 Lucene.Net.Analysis.CharFilter

Subclasses of CharFilter can be chained to filter a Reader They can be used as java.io.Reader with additional offset correction. Tokenizers will automatically use #correctOffset if a CharFilter subclass is used.

this class is abstract: at a minimum you must implement #read(char[], int, int), transforming the input in some way from #input, and #correct(int) to adjust the offsets to match the originals.

You can optionally provide more efficient implementations of additional methods like #read(), #read(char[]), #read(java.nio.CharBuffer), but this is not required.

For examples and integration with Analyzer, see the Lucene.Net.Analysis Analysis package documentation.

메소드	설명
Close ( ) : void	Closes the underlying input stream. NOTE: The default implementation closes the input Reader, so be sure to call `super.close()` when overriding this method.
CorrectOffset ( int currentOff ) : int	Chains the corrected offset through the input CharFilter(s).
Mark ( int readAheadLimit ) : void	Marks the present position in the stream. Subsequent calls to reset() will attempt to reposition the stream to this point. Not all character-input streams support the mark() operation. LUCENENET specific. Moved here from the Java Reader class so it can be overridden to provide reader buffering.
Ready ( ) : bool	Tells whether this stream is ready to be read. True if the next read() is guaranteed not to block for input, false otherwise. Note that returning false does not guarantee that the next read will block. LUCENENET specific. Moved here from the Java Reader class so it can be overridden to provide reader buffering.
Reset ( ) : void	LUCENENET specific. Moved here from the Java Reader class so it can be overridden to provide reader buffering.
Skip ( int n ) : long	Skips characters. This method will block until some characters are available, an I/O error occurs, or the end of the stream is reached. LUCENENET specific. Moved here from the Java Reader class so it can be overridden to provide reader buffering.
