Examples of StandardEvaluationContext

org.springframework.expression.spel.support.StandardEvaluationContext
Provides a default EvaluationContext implementation.
To resolve properties/methods/fields this context uses a reflection mechanism. @author Andy Clement @author Juergen Hoeller @author Sam Brannen @since 3.0
