Methods

  Method Description
Gg839532.pubmethod(en-us,AX.60).gif assert Declares that the calling code can invoke an API that is protected by a permission. (Inherited from CodeAccessPermission.)
Gg839532.pubmethod(en-us,AX.60).gif cancelTimeOut Cancels a previous method call to the setTimeOut method. (Inherited from Object.)
Gg839532.pubmethod(en-us,AX.60).gif copy Creates and returns a copy of the current permission class object. (Overrides the copy Method.)
Gg839532.pubmethod(en-us,AX.60).gif demand Checks the call stack to determine whether the permission that is required to invoke an API has been granted to the calling code. (Inherited from CodeAccessPermission.)
Gg839532.pubmethod(en-us,AX.60).gif equal Determines whether the specified object is equal to the current one. (Inherited from Object.)
Gg839532.pubmethod(en-us,AX.60).gif getTimeOutTimerHandle Returns the timer handle for the object. (Inherited from Object.)
Gg839532.pubmethod(en-us,AX.60).gif handle Retrieves the handle of the class of the object. (Inherited from Object.)
Gg839532.pubmethod(en-us,AX.60).gif isSubsetOf Determines whether a current permission is a subset of the specified permission. (Overrides the isSubsetOf Method.)
Gg839532.pubmethod(en-us,AX.60).gif new Initializes a new instance of the ExecutePermission class. (Overrides the new Method.)
Gg839532.pubmethod(en-us,AX.60).gif notify Releases the hold on an object that has called the wait method on this object. (Inherited from Object.)
Gg839532.pubmethod(en-us,AX.60).gif notifyAll Releases a lock on the object that was issued by the wait method on this object. (Inherited from Object.)
Gg839532.pubmethod(en-us,AX.60).gif objectOnServer Determines whether the object is on a server. (Inherited from Object.)
Gg839532.pubmethod(en-us,AX.60).gif owner Returns the instance that owns the object. (Inherited from Object.)
Gg839532.pubmethod(en-us,AX.60).gif setTimeOut Sets up the scheduled execution of a specified method. (Inherited from Object.)
Gg839532.pubmethod(en-us,AX.60).gif toString Returns a string that represents the current object. (Inherited from Object.)
Gg839532.pubmethod(en-us,AX.60).gif usageCount Returns the current number of references, that is, the value of the reference counter, that the object has. (Inherited from Object.)
Gg839532.pubmethod(en-us,AX.60).gif wait Pauses a process. (Inherited from Object.)
Gg839532.pubmethod(en-us,AX.60).gif xml Returns an XML string that represents the current object. (Inherited from Object.)

Remarks

This class is designed to check permissions for specific APIs. For a list of all APIs that are protected by permissions, see Secured APIs.

Before the protected API is executed, you must call the assert method on the same tier (which is usually the server tier) that the corresponding CodeAccessPermission::demand method is called on. Call a method on the server tier from one of the following methods:

  • A server static method

  • A class instance method that is set to run on the server by using the RunOn class property

Examples

The following code example shows a new instance of the ExecutePermission class.

The assert method is called to declare that the code can then call the Thread.new method to create a new thread.

server static void main(Args args) 
{ 
    Thread _t; 
    ExecutePermission _perm; 
 
    _perm = new ExecutePermission(); 
    if (!_perm) 
    { 
        return; 
    } 
 
    _perm.assert(); 
 
    // Invoke the protected API. 
     _t = new Thread(); 
 
    // Call member methods. 
    if (_t) 
    { 
        _t.removeOnComplete(true); 
        _t.run(classnum(SysCodeProfiler), identifierstr(transferFile)); 
    } 
 
    // Optionally, call revertAssert() to limit scope of assert. 
    CodeAccessPermission::revertAssert(); 
}
