Interface Summary

Interface	Description
BeanResolver	A bean resolver can be registered with the evaluation context and will kick in for @myBeanName still expressions.
ConstructorExecutor	Executors are built by resolvers and can be cached by the infrastructure to repeat an operation quickly without going back to the resolvers.
ConstructorResolver	A constructor resolver attempts locate a constructor and returns a ConstructorExecutor that can be used to invoke that constructor.
EvaluationContext	Expressions are executed in an evaluation context.
Expression	An expression capable of evaluating itself against context objects.
ExpressionParser	Parses expression strings into compiled expressions that can be evaluated.
MethodExecutor	MethodExecutors are built by the resolvers and can be cached by the infrastructure to repeat an operation quickly without going back to the resolvers.
MethodFilter	MethodFilter instances allow SpEL users to fine tune the behaviour of the method resolution process.
MethodResolver	A method resolver attempts locate a method and returns a command executor that can be used to invoke that method.
OperatorOverloader	By default the mathematical operators Operation support simple types like numbers.
ParserContext	Input provided to an expression parser that can influence an expression parsing/compilation routine.
PropertyAccessor	A property accessor is able to read from (and possibly write to) an object's properties.
TypeComparator	Instances of a type comparator should be able to compare pairs of objects for equality.
TypeConverter	A type converter can convert values between different types encountered during expression evaluation.
TypeLocator	Implementers of this interface are expected to be able to locate types.

Class Summary

Class	Description
TypedValue	Encapsulates an object and a TypeDescriptor that describes it.

Enum Summary

Enum	Description
Operation	Supported operations that an OperatorOverloader can implement for any pair of operands.

Exception Summary

Exception	Description
AccessException	An AccessException is thrown by an accessor if it has an unexpected problem.
EvaluationException	Represent an exception that occurs during expression evaluation.
ExpressionException	Super class for exceptions that can occur whilst processing expressions.
ExpressionInvocationTargetException	This exception wraps (as cause) a checked exception thrown by some method that SpEL invokes.
ParseException	Represent an exception that occurs during expression parsing.
