cn.taketoday.expression使用的cn.taketoday.expression中的类

类	说明
AccessException	An AccessException is thrown by an accessor if it has an unexpected problem.
BeanResolver	A bean resolver can be registered with the evaluation context and will kick in for bean references: @myBeanName and &myBeanName 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.
EvaluationException	Represent an exception that occurs during expression evaluation.
Expression	An expression capable of evaluating itself against context objects.
ExpressionException	Super class for exceptions that can occur whilst processing expressions.
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.
MethodResolver	A method resolver attempts to locate a method and returns a command executor that can be used to invoke that method.
Operation	Supported operations that an OperatorOverloader can implement for any pair of operands.
OperatorOverloader	By default the mathematical operators Operation support simple types like numbers.
ParseException	Represent an exception that occurs during expression parsing.
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.
TypedValue	Encapsulates an object and a TypeDescriptor that describes it.
TypeLocator	Implementers of this interface are expected to be able to locate types.
