Interface Summary

Interface	Description
EvalFactoryNode
EvalFactoryNodeVisitor
EvalForgeNode	Superclass of all nodes in an evaluation tree representing an event pattern expression.
EvalNode
EvalNodeUtilFactoryFilter
EvalRootMatchRemover	Interface for a root pattern node for removing matches.
EvalRootState	Interface for a root state node accepting a callback to use to indicate pattern results.
EvalStateNodeVisitor	Interface for visiting each element in the evaluation node tree for an event expression (see Visitor pattern).
Evaluator	Interface for nodes in an expression evaluation state tree that are being informed by a child that the event expression fragments (subtrees) which the child represents has turned true (evaluateTrue method) or false (evaluateFalse).
MatchedEventConvertor	Converts from a map of prior matching events to a events per stream for resultion by expressions.
PatternCompileHook
PatternDeltaCompute
PatternFactoryService
PatternMatchCallback	Callback interface for anything that requires to be informed of matching events which would be stored in the MatchedEventMap structure passed to the implementation.
PatternObjectResolutionService	Factory service for resolving pattern objects such as guards and observers.
