Mark whether or not the underlying system table has been scanned. (If a table does not have any constraints then the size of its CDL will always be 0. We used these get/set methods to determine when we need to scan the table.

Parameters:

scanned - Whether or not the underlying system table has been scanned.

getScanned

public boolean getScanned()

Return whether or not the underlying system table has been scanned.

Returns:

Where or not the underlying system table has been scanned.

getUniqueTupleDescriptor

public E getUniqueTupleDescriptor(UUID uuid)

Get the UniqueTupleDescriptor that matches the input uuid.

Parameters:

uuid - The UUID for the object

Returns:

The matching UniqueTupleDescriptor.
