Class JCasImpl

java.lang.Object

org.apache.uima.cas.AbstractCas_ImplBase

org.apache.uima.jcas.impl.JCasImpl

All Implemented Interfaces:

AbstractCas, JCas

public class JCasImpl
extends AbstractCas_ImplBase
implements AbstractCas, JCas

implements the supporting infrastructure for JCas model linked with a Cas. There is one logical instance of this instantiated per Cas or CasView. If you hold a reference to a CAS, to get a reference to the corresponding JCas, use the method getJCas(). Likewise, if you hold a reference to this object, you can get a reference to the corresponding CAS object using the method getCas().

There are variables here that hold references to constant, frequently needed Cas values, such as 0-length FSArrays, 0-length Strings, etc. These can be used to improve efficiency, since the same object can be shared and used for all instances because it is unchangeable. These objects are reset when the CAS is reset, and are initialized lazily, on first use.
