ClassDescriptionAn AccessException is thrown by an accessor if it has an unexpected problem.A bean resolver can be registered with the evaluation context and will kick in for bean references:
@myBeanName
and&myBeanName
expressions.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.A property accessor is able to read from (and possibly write to) an object's properties.Encapsulates an object and aTypeDescriptor
that describes it. -

expressions.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 to locate a constructor and returns a ConstructorExecutor that can be used to invoke that constructor.Expressions are executed in an evaluation context.Represent an exception that occurs during expression evaluation.An expression capable of evaluating itself against context objects.Superclass for exceptions that can occur whilst processing expressions.MethodExecutors are built by the resolvers and can be cached by the infrastructure to repeat an operation quickly without going back to the resolvers.A method resolver attempts to locate a method and returns a command executor that can be used to invoke that method.Supported operations that anOperatorOverloader
can implement for any pair of operands.By default the mathematical operatorsOperation
support simple types like numbers.Represent an exception that occurs during expression parsing.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.Encapsulates an object and aTypeDescriptor
that describes it.Implementers of this interface are expected to be able to locate types. -
