Description copied from interface: I_CmsPermissionHandler

Performs a non-blocking permission check on a resource.

This test will not throw an exception in case the required permissions are not available for the requested operation. Instead, it will return one of the following values:

• I_CmsPermissionHandler.PERM_ALLOWED
• I_CmsPermissionHandler.PERM_FILTERED
• I_CmsPermissionHandler.PERM_DENIED

Despite of the fact that the results of this method are cached, this method should be as fast as possible since it is called really often.

Specified by:

hasPermissions in interface I_CmsPermissionHandler

Parameters:

dbc - the current database context

resource - the resource on which permissions are required

requiredPermissions - the set of permissions required for the operation

checkLock - if true, a lock for the current user is required for all write operations, if false it's ok to write as long as the resource is not locked by another user

filter - the resource filter to use

Returns:

I_CmsPermissionHandler.PERM_ALLOWED if the user has sufficient permissions on the resource for the requested operation

Throws:

CmsException - in case of i/o errors (NOT because of insufficient permissions)
