Interface CompatibilitySpace

All Known Implementing Classes:
LockSpace

public interface CompatibilitySpace

This interface must be implemented by objects returned from LockFactory.createCompatibilitySpace().

A CompatibilitySpace can have an owner (for instance a transaction). Currently, the owner is used by the virtual lock table to find out which transaction a lock belongs to. Some parts of the code also use the owner as a group object which guarantees that the lock is released on a commit or an abort. The owner has no special meaning to the lock manager and can be any object, including null.
