Examples of org.eclipse.jdt.debug.eval.IAstEvaluationEngine

org.eclipse.jdt.debug.eval.IAstEvaluationEngine
An evaluation engine that performs evaluations by interpreting abstract syntax trees. An AST evaluation engine is capable of creating compiled expressions that can be evaluated multiple times in a given runtime context. @since 2.0 @noimplement This interface is not intended to be implemented by clients. @noextend This interface is not intended to be extended by clients.
