Examples of org.apache.derby.catalog.DependableFinder

org.apache.derby.catalog.DependableFinder
A DependableFinder is an object that can find an in-memory Dependable, given the Dependable's ID.
The DependableFinder is able to write itself to disk and, once read back into memory, locate the in-memory Dependable that it represents.
DependableFinder objects are stored in SYS.SYSDEPENDS to record dependencies between database objects.
