Package org.springframework.integration.expression

Provides classes supporting SpEL expressions.

Interface Summary

Interface	Description
ExpressionEvalMap.EvaluationCallback	Implementations of this interface can be provided to build 'on demand ExpressionEvalMap.get(Object) logic' for ExpressionEvalMap.
ExpressionEvalMap.ExpressionEvalMapComponentsBuilder
ExpressionEvalMap.ExpressionEvalMapFinalBuilder
ExpressionSource	Strategy interface for retrieving Expressions.

Class Summary

Class	Description
ControlBusMethodFilter	SpEL MethodFilter to restrict method invocations to: Pausable or Lifecycle components get, set and shutdown methods of CustomizableThreadCreator methods with ManagedAttribute and ManagedOperation annotations This class isn't designed for target applications and typically is used from ExpressionControlBusFactoryBean.
DynamicExpression	An implementation of Expression that delegates to an ExpressionSource for resolving the actual Expression instance per-invocation at runtime.
ExpressionEvalMap	An immutable AbstractMap implementation that wraps a Map<String, Object>, where values must be instances of String or Expression, and evaluates an expression for the provided key from the underlying original Map.
ExpressionEvalMap.ComponentsEvaluationCallback	The ExpressionEvalMap.EvaluationCallback implementation which evaluates an expression using the provided context, root and returnType variables.
ExpressionEvalMap.ExpressionEvalMapBuilder	The builder class to instantiate ExpressionEvalMap.
ExpressionUtils	Utility class with static methods for helping with evaluation of SpEL expressions.
FunctionExpression<S>	An Expression that simply invokes Function.apply(Object) on its provided Function.
ReloadableResourceBundleExpressionSource	ExpressionSource implementation that accesses resource bundles using specified basenames.
SpelPropertyAccessorRegistrar	Utility class that keeps track of a Set of SpEL PropertyAccessors in order to register them with the "integrationEvaluationContext" upon initialization.
SupplierExpression<T>	An Expression that simply invokes Supplier.get() on its provided Supplier.
ValueExpression<V>	A very simple hardcoded implementation of the Expression interface that represents an immutable value.
