StandardEvaluationContext

extends Object
implements EvaluationContext

Class Overview

Provides a default EvaluationContext implementation.

To resolve properties/methods/fields this context uses a reflection mechanism.

public Object lookupVariable (String name)

Look up a named variable within this evaluation context.

Parameters
name variable to lookup
Returns
  • the value of the variable

public void registerFunction (String name, Method method)

public void registerMethodFilter (Class<?> type, MethodFilter filter)

Register a MethodFilter which will be called during method resolution for the specified type. The MethodFilter may remove methods and/or sort the methods which will then be used by SpEL as the candidates to look through for a match.

Parameters
type the type for which the filter should be called
filter a MethodFilter, or NULL to deregister a filter for the type
