Examples of org.apache.uima.cas.CAS.reset()

org.apache.uima.cas.CAS.reset()
Reset the CAS, emptying it of all content. Feature structures and iterators will no longer be valid. Note: this method may only be called from an application. Calling it from an annotator will trigger a runtime exception. @throws CASRuntimeException When called out of sequence. @see org.apache.uima.cas.admin.CASMgr
