Class ExtractionContextBlocker

java.lang.Object

org.apache.any23.filter.ExtractionContextBlocker

All Implemented Interfaces:

TripleHandler

public class ExtractionContextBlocker
extends Object
implements TripleHandler

A wrapper around a TripleHandler that can block and unblock calls to the handler, either for the entire document, or for individual ExtractionContexts. A document is initially blocked and must be explicitly unblocked. Contexts are initially unblocked and must be explicitly blocked. Unblocking a document unblocks all contexts as well. This class it thread-safe.
