```
    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.
