A bean resolver can be registered with the evaluation context and will kick in for bean references:
Executors are built by resolvers and can be cached by the infrastructure to repeat an operation quickly without going back to the resolvers.
A constructor resolver attempts locate a constructor and returns a ConstructorExecutor that can be used to invoke that constructor.
Expressions are executed in an evaluation context.
An expression capable of evaluating itself against context objects.
Parses expression strings into compiled expressions that can be evaluated.
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 instances allow SpEL users to fine tune the behaviour of the method resolution process.
A method resolver attempts locate a method and returns a command executor that can be used to invoke that method.
By default the mathematical operators
Input provided to an expression parser that can influence an expression parsing/compilation routine.
A property accessor is able to read from (and possibly write to) an object's properties.
Instances of a type comparator should be able to compare pairs of objects for equality.
A type converter can convert values between different types encountered during expression evaluation.
Implementers of this interface are expected to be able to locate types.
Encapsulates an object and a
Supported operations that an
An AccessException is thrown by an accessor if it has an unexpected problem.
Represent an exception that occurs during expression evaluation.
Super class for exceptions that can occur whilst processing expressions.
This exception wraps (as cause) a checked exception thrown by some method that SpEL invokes.
Represent an exception that occurs during expression parsing.
