Class MappingCharFilter

  • All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable, java.lang.Readable
    public class MappingCharFilter
extends BaseCharFilter
    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.
