IExpressionEvaluator

Property Documentation

virtual IExpressionEvaluatorService CSF.Zpt.Tales.SimpleEvaluatorSelector.EvaluatorRegistry

getprotected

Gets the expression evaluator registry instance.

This is lazily initialised, because instances of SimpleEvaluatorSelector might be initialised by types which are registered with the individual evaluators. Thus, in order to avoid a scenario in which we are referencing the default registry before it has finished constructing, we ensure that we don't touch it until we need it.

The evaluator registry.
