C# Class Lucene.Net.Analysis.CharFilters.MappingCharFilter

Simplistic CharFilter that applies the mappings contained in a NormalizeCharMap to the character stream, and correcting the resulting changes to the offsets. Matching is greedy (longest pattern matching at a given point wins). Replacement is allowed to be the empty string.

Private Methods

Method	Description
GetBufferedReader ( TextReader reader ) : BufferedCharFilter	LUCENENET: Copied this method from the WordlistLoader class - this class requires readers with a Reset() method (which .NET readers don't support). So, we use the BufferedCharFilter (which is similar to Java BufferedReader) as a wrapper for whatever reader the user passes (unless it is already a BufferedCharFilter).
