boolean isBoundary(Annotation contextAnnotation, int scopeOrientation) throws AnalysisEngineProcessException
For the left and right scopes, the context annotator will collect a number of annotations up to the maximum specified by the appropriate parameter unless it comes to the edge of the window annotation or a boundary condition is met as specified by this method. For example, you may specify that the scope is LEFT, the maximum left scope size is 10, the context annotation is a token of some sort, and the window annotation is a sentence. The context annotator will collect the annotations to the left of the focus annotation such that there will be no more than 10 context annotations, they will all be inside the sentence, and no context annotations will be collected to the left of a boundary condition as specified by this method.
contextAnnotation
- the context annotation that may or may not satisfy a boundary
conditionscopeOrientation
- the scope of the context annotator. The value will be the left
or right scope.AnnotatorProcessException

ContextHit analyzeContext(java.util.List<? extends Annotation> contextAnnotations, int scopeOrientation) throws AnalysisEngineProcessException
This method analyzes a list of context annotations to determine if there is a "context hit" - some event that we are looking for in the context.
contextAnnotations
- the annotations to be analyzedscopeOrientation
- the scope of the context annotator. The value will be the
left, right, middle, or "all" context.AnnotatorProcessException
