Class TagLL

java.lang.Object
org.apache.solr.handler.tagger.TagLL
public class TagLL extends Object
This is a Tag -- a startOffset, endOffset and value.

A Tag starts without a value in an "advancing" state. advance(org.apache.lucene.util.BytesRef, int) is called with subsequent words and then eventually it won't advance any more, and value is set (could be null).

A Tag is also a doubly-linked-list (hence the LL in the name). All tags share a reference to the head via a 1-element array, which is potentially modified if any of the linked-list methods are called. Tags in the list should have equal or increasing start offsets.

  • Method Details

    • removeLL

      public void removeLL()
      Removes this tag from the chain, connecting prevTag and nextTag. Does not modify "this" object's pointers, so the caller can refer to nextTag after removing it.
