Interface Summary Interface Description AnnotatedArrayType AnnotatedArrayType
represents the potentially annotated use of an array type, whose component type may itself represent the annotated use of a type.AnnotatedElement Represents an annotated element of the program currently running in this VM.AnnotatedParameterizedType AnnotatedParameterizedType
represents the potentially annotated use of a parameterized type, whose type arguments may themselves represent annotated uses of types.AnnotatedType AnnotatedType
represents the potentially annotated use of a type in the program currently running in this VM.AnnotatedTypeVariable AnnotatedTypeVariable
represents the potentially annotated use of a type variable, whose declaration may have bounds which themselves represent annotated uses of types.AnnotatedWildcardType AnnotatedWildcardType
represents the potentially annotated use of a wildcard type argument, whose upper or lower bounds may themselves represent annotated uses of types.GenericArrayType GenericArrayType
represents an array type whose component type is either a parameterized type or a type variable.GenericDeclaration A common interface for all entities that declare type variables.InvocationHandler InvocationHandler
is the interface implemented by the invocation handler of a proxy instance.Member Member is an interface that reflects identifying information about a single member (a field or a method) or a constructor.ParameterizedType ParameterizedType represents a parameterized type such as Collection<String>.Type Type is the common superinterface for all types in the Java programming language.TypeVariable<D extends GenericDeclaration> TypeVariable is the common superinterface for type variables of kinds.WildcardType WildcardType represents a wildcard type expression, such as?
,? extends Number
, or? super Integer

Class Summary Class Description AccessibleObject The AccessibleObject class is the base class for Field, Method and Constructor objects.Array TheArray
class provides static methods to dynamically create and access Java arrays.Constructor<T> Constructor
provides information about, and access to, a single constructor for a class.Executable A shared superclass for the common functionality ofMethod
andConstructor
.Field AField
provides information about, and dynamic access to, a single field of a class or an interface.Method AMethod
provides information about, and access to, a single method on a class or interface.Modifier The Modifier class providesstatic
methods and constants to decode class and member access modifiers.Parameter Information about method parameters.Proxy 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.ReflectPermission The Permission class for reflective operations. -
Exception Summary Exception Description InvocationTargetException InvocationTargetException is a checked exception that wraps an exception thrown by an invoked method or constructor.MalformedParameterizedTypeException Thrown when a semantically malformed parameterized type is encountered by a reflective method that needs to instantiate it.MalformedParametersException Thrown whenthe java.lang.reflect package
attempts to read method parameters from a class file and determines that one or more parameters are malformed.UndeclaredThrowableException Thrown by a method invocation on a proxy instance if its invocation handler'sinvoke
method throws a checked exception (aThrowable
that is not assignable toRuntimeException
orError
) that is not assignable to any of the exception types declared in thethrows
clause of the method that was invoked on the proxy instance and dispatched to the invocation handler. -
Error Summary Error Description GenericSignatureFormatError 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.
Package java.lang.reflect Description
AccessibleObject
allows suppression of access checks if the necessary ReflectPermission
is available.
Array
provides static methods to dynamically create and access arrays.
Classes in this package, along with java.lang.Class
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.
