Class SelectiveFoldingFilter

  • All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable
    public final class SelectiveFoldingFilter
extends org.apache.lucene.analysis.TokenFilter
    A Lucene filter based on ASCIIFoldingFilter, but that allows the caller to provide a white list for selective folding filter. Entries in the white list are ignored during the filtering. This is useful for languages that require certain characters to be ignored.
