Method Detail

clone

public java.lang.Object clone()

Overrides:

clone in class java.lang.Object

getCatalogNumber

public abstract int getCatalogNumber()

setGrantee

public void setGrantee(java.lang.String grantee)

getGrantee

public final java.lang.String getGrantee()

getGrantor

public final java.lang.String getGrantor()

getUUID

public UUID getUUID()

Gets the UUID of the table.

Returns:

The UUID of the table.

setUUID

public void setUUID(UUID oid)

Sets the UUID of the table

Parameters:

oid - The UUID of the table to be set in the descriptor

checkOwner

public abstract boolean checkOwner(java.lang.String authorizationId)
                            throws StandardException

This method checks if the passed authorization id is same as the owner of the object on which this permission is defined. This method gets called by create view/constraint/trigger to see if this permission needs to be saved in dependency system for the view/constraint/trigger. 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

Returns:

boolean If passed authorization id is owner of the table

Throws:

StandardException

getObjectID

public UUID getObjectID()

Get the provider's UUID

Specified by:

getObjectID in interface Dependable

Returns:

The provider's UUID

isPersistent

public boolean isPersistent()

Is this provider persistent? A stored dependency will be required if both the dependent and provider are persistent.

Specified by:

isPersistent in interface Dependable

Overrides:

isPersistent in class TupleDescriptor

Returns:

boolean Whether or not this provider is persistent.
