Method insertsSafety

src/main/java/gate/corpora/DocumentImpl.java:901–944

This method verifies if aSourceAnnotation can ve inserted safety into the aTargetAnnotSet. Safety means that it doesn't violate the crossed over contition with any annotation from the aTargetAnnotSet. @param aTargetAnnotSet the annotation set to include the aSourceAnnotation @param aSource

(AnnotationSet aTargetAnnotSet,
          Annotation aSourceAnnotation)

   * @return true if the annotation inserts safety, or false otherwise.
