checkOwner

public boolean checkOwner(String authorizationId)
                   throws StandardException

Description copied from class: PermissionsDescriptor

This method checks if the passed authorization id is same as the owner of the object on which this permission is defined.

If the same user is the owner of the the object being accessed and the newly created object, then no need to keep this privilege dependency

Specified by:

checkOwner in class PermissionsDescriptor

Returns:

boolean If passed authorization id is owner of the table

Throws:

Returns:

String The name of this provider.

getClassType

public String getClassType()

Get the provider's type.

Returns:

char The provider's type.

getDependableFinder

public DependableFinder getDependableFinder()

Description copied from interface: Dependable

Get an object which can be written to disk and which, when read from disk, will find or reconstruct this in-memory Dependable.

Returns:

the stored form of this provider
