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.
AnnotatedArrayTyperepresents the potentially annotated use of an array type, whose component type may itself represent the annotated use of a type.Represents an annotated construct of the program currently running in this VM.
AnnotatedParameterizedTyperepresents the potentially annotated use of a parameterized type, whose type arguments may themselves represent annotated uses of types.
AnnotatedTyperepresents the potentially annotated use of a type in the program currently running in this VM.
AnnotatedTypeVariablerepresents the potentially annotated use of a type variable, whose declaration may have bounds which themselves represent annotated uses of types.
AnnotatedWildcardTyperepresents the potentially annotated use of a wildcard type argument, whose upper or lower bounds may themselves represent annotated uses of types.
GenericArrayTyperepresents 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.
InvocationHandleris 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
Collection<String>.Type is the common superinterface for all types in the Java programming language.TypeVariable is the common superinterface for type variables of kinds.WildcardType represents a wildcard type expression, such as
? extends Number, or
? super Integer.
AccessibleObjectclass is the base class for
Constructorobjects (known as reflected objects).The
Arrayclass provides static methods to dynamically create and access Java arrays.Constructor<T>
Constructorprovides information about, and access to, a single constructor for a class.A
Fieldprovides information about, and dynamic access to, a single field of a class or an interface.A
Methodprovides information about, and access to, a single method on a class or interface.The Modifier class provides
staticmethods and constants to decode class and member access modifiers.Information about method parameters.
Proxyprovides static methods for creating objects that act like instances of interfaces but allow for customized method invocation.A
RecordComponentprovides information about, and dynamic access to, a component of a record class.The Permission class for reflective operations.
ExceptionDescriptionThrown when Java language access checks cannot be suppressed.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 when
the java.lang.reflect packageattempts to read method parameters from a class file and determines that one or more parameters are malformed.Thrown by a method invocation on a proxy instance if its invocation handler's
invokemethod throws a checked exception (a
Throwablethat is not assignable to
Error) that is not assignable to any of the exception types declared in the
throwsclause of the method that was invoked on the proxy instance and dispatched to the invocation handler.
ErrorDescriptionThrown when a syntactically malformed signature attribute is encountered by a reflective method that needs to interpret the generic signature information for a class or interface, method or constructor.
