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.

getNextTag

public TagLL getNextTag()

getPrevTag

public TagLL getPrevTag()

getStartOffset

public int getStartOffset()

getEndOffset

public int getEndOffset()

overlaps

public boolean overlaps(TagLL other)

toString

public String toString()

Overrides:
