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
.
