java.lang.Class< T > Class Reference

Detailed Description

This class must be implemented by the VM vendor.

The documented natives must be implemented to support other provided class implementations in this package. An instance of class Class is the in-image representation of a Java class. There are three basic types of Classes

Classes representing object types (classes or interfaces)

These are Classes which represent the class of a simple instance as found in the class hierarchy. The name of one of these Classes is simply the fully qualified class name of the class or interface that it represents. Its signature is the letter "L", followed by its name, followed by a semi-colon (";").

Classes representing base types

These Classes represent the standard Java base types. Although it is not possible to create new instances of these Classes, they are still useful for providing reflection information, and as the component type of array classes. There is one of these Classes for each base type, and their signatures are:

B representing the byte base type
S representing the short base type
I representing the int base type
J representing the long base type
F representing the float base type
D representing the double base type
C representing the char base type
Z representing the boolean base type
V representing void function return values

The name of a Class representing a base type is the keyword which is used to represent the type in Java source code (i.e. "int" for the int base type.

Classes representing array classes

These are Classes which represent the classes of Java arrays. There is one such Class for all array instances of a given arity (number of dimensions) and leaf component type. In this case, the name of the class is one or more left square brackets (one per dimension in the array) followed by the signature ofP the class representing the leaf component type, which can be either an object type or a base type. The signature of a Class representing an array type is the same as its name.

Member Function Documentation

static final Class [] java.lang.Class< T >.getStackClasses	(	int	maxDepth,
		boolean	stopAtPrivileged
	)			`[static, package]`

This must be provided by the VM vendor, as it is used by other provided class implementations in this package.

This method is used by SecurityManager.classDepth(), and getClassContext() which use the parameters (-1, false) and SecurityManager.classLoaderDepth(), currentClassLoader(), and currentLoadedClass() which use the parameters (-1, true). Walk the stack and answer an array containing the maxDepth most recent classes on the stack of the calling thread. Starting with the caller of the caller of getStackClasses(), return an array of not more than maxDepth Classes representing the classes of running methods on the stack (including native methods). Frames representing the VM implementation of java.lang.reflect are not included in the list. If stopAtPrivileged is true, the walk will terminate at any frame running one of the following methods:



java/security/AccessController.doPrivileged(Ljava/security/PrivilegedAction;)Ljava/lang/Object; 

java/security/AccessController.doPrivileged(Ljava/security/PrivilegedExceptionAction;)Ljava/lang/Object; 

java/security/AccessController.doPrivileged(Ljava/security/PrivilegedAction;Ljava/security/AccessControlContext;)Ljava/lang/Object; 

java/security/AccessController.doPrivileged(Ljava/security/PrivilegedExceptionAction;Ljava/security/AccessControlContext;)Ljava/lang/Object;

If one of the doPrivileged methods is found, the walk terminate and that frame is NOT included in the returned array. Notes:

This method operates on the defining classes of methods on stack. NOT the classes of receivers.
The item at index zero in the result array describes the caller of the caller of this method.

Parameters:

	maxDepth	maximum depth to walk the stack, -1 for the entire stack
	stopAtPrivileged	stop at privileged classes

Returns:: the array of the most recent classes on the stack
