org.wildfly.common.context.ContextPermission

All Implemented Interfaces:

Serializable, Guard

public final class ContextPermission
extends Permission

A permission object for operations on ContextManager instances.

This type of permission requires a name and an action. The name may be the name of a context manager, or the special * name which means the permission applies to all context managers.

The action may be one or more of the following (each action name being separated by a comma):

• get - allow getting the current context
• getPrivilegedSupplier - allow access to the ContextManager.getPrivilegedSupplier() method
• getGlobalDefault - allow access to the global default context
• setGlobalDefault - allow setting the global default instance
• setGlobalDefaultSupplier - allow setting the global default instance supplier
• getThreadDefault - allow access to the per-thread default context
• setThreadDefault - allow setting the per-thread default instance
• setThreadDefaultSupplier - allow setting the per-thread default instance supplier

Additionally, the special * action name is allowed which implies all of the above actions.

The newPermissionCollection() method returns an optimized container for context permissions.
