Class MultiTextSpan

java.lang.Object

org.apache.ctakes.dictionary.lookup2.textspan.MultiTextSpan

All Implemented Interfaces:

TextSpan

@Immutable
public final class MultiTextSpan
extends Object
implements TextSpan

A useful key for hash collections based upon start and end indices and missing internal spans. This is faster than using String as String.hashCode() iterates over the internal character array of a new string (new(..), .substring(..), .lowercase(..), ...).

There is a much better version of this in org.chboston.chip.nlp.annotation but this will do for now.
