◆ enter() [2/2]

static <T extends AbstractContext> T javolution.context.AbstractContext.enter ( Class< T > custom )

staticinherited

Enters the scope of a custom context. This method raises a SecurityException if the permission to enter contexts of the specified class is not granted. For example, the following disallow entering any custom context. [code] SecurityContext ctx = SecurityContext.enter(); try { ctx.revoke(new SecurityContext.Permission(AbstractContext.class, "enter")); ... // Cannot enter any custom context. } finally { ctx.exit(); // Back to previous security settings. }[/code]

Parameters

custom the custom context to enter.

Exceptions

IllegalArgumentException	if the specified class default constructor cannot be instantiated.
SecurityException	if SecurityContext.Permission(custom, "enter") is not granted.
