Provides classes and interfaces for obtaining reflective
information about classes and objects. Reflection allows
programmatic access to information about the fields, methods and
constructors of loaded classes, and the use of reflected fields,
methods, and constructors to operate on their underlying
counterparts, within security restrictions.
AccessibleObject allows suppression of access checks if
ReflectPermission is available.
Array provides static methods to dynamically create and
Classes in this package, along with
accommodate applications such as debuggers, interpreters, object
inspectors, class browsers, and services such as Object
Serialization and JavaBeans that need access to either the public
members of a target object (based on its runtime class) or the
members declared by a given class.
||Represents an annotated element of the program currently running in this
GenericArrayType represents an array type whose component
type is either a parameterized type or a type variable.
||A common interface for all entities that declare type variables.
InvocationHandler is the interface implemented by
the invocation handler of a proxy instance.
||Member is an interface that reflects identifying information about
a single member (a field or a method) or a constructor.
||ParameterizedType represents a parameterized type such as
||Type is the common superinterface for all types in the Java
||WildcardType represents a wildcard type expression, such as
? extends Number, or
? super Integer.
||The AccessibleObject class is the base class for Field, Method and
Array class provides static methods to dynamically create and
access Java arrays.
Constructor provides information about, and access to, a single
constructor for a class.
||A shared superclass for the common functionality of
Field provides information about, and dynamic access to, a
single field of a class or an interface.
Method provides information about, and access to, a single method
on a class or interface.
||The Modifier class provides
static methods and
constants to decode class and member access modifiers.
Proxy provides static methods for creating dynamic proxy
classes and instances, and it is also the superclass of all
dynamic proxy classes created by those methods.
||Legacy security code; do not use.
||InvocationTargetException is a checked exception that wraps
an exception thrown by an invoked method or constructor.
||Thrown when a semantically malformed parameterized type is
encountered by a reflective method that needs to instantiate it.
||Thrown by a method invocation on a proxy instance if its invocation
invoke method throws a
checked exception (a
Throwable that is not assignable
is not assignable to any of the exception types declared in the
throws clause of the method that was invoked on the
proxy instance and dispatched to the invocation handler.
||Thrown when a syntactically malformed signature attribute is
encountered by a reflective method that needs to interpret the
generic signature information for a type, method or constructor.
