protected int classLoaderDepth()

This utility method for security managers searches the execution stack for the cur 

rent thread to find the most recently invoked method whose execution has not yet

completed and whose class was created by a class loader ( 20.14). If such a

method is found, its distance from the top of the stack is returned as a nonnegative

integer; otherwise,

 1

 is returned.

20.17.8

protected boolean inClassLoader()

This utility method for security managers searches the execution stack for the cur 

rent thread to find the most recently invoked method whose execution has not yet

completed and whose class was created by a class loader ( 20.14). If such a

method is found,

true

 is returned; otherwise

false

 is returned.

20.17.9

public boolean getInCheck()

The value of the

inCheck

 field ( 20.17.1) is returned.

20.17.10

public void checkCreateClassLoader()

throws SecurityException

The general contract of this method is that it should throw a

SecurityException

if creation of a class loader is not permitted.

This method is invoked for the current security manager ( 20.18.4) by the

constructor for class

ClassLoader

 ( 20.14.1).

The

checkCreateClassLoader

 method defined by class

SecurityManager

always throws a

SecurityException

. A subclass must override this method if a

class loader creation operation is to be permitted with a security manager

installed.

20.17.11

public void checkAccess(Thread t)

throws SecurityException

The general contract of this method is that it should throw a

SecurityException

if an operation that would modify the thread

t

 is not permitted.

This method is invoked for the current security manager ( 20.18.4) by method

checkAccess

 ( 20.20.12) of class

Thread

.
