Method Details

getPriority

public int getPriority(Class<? extends DatabaseObject> objectType,
 Database database)

Description copied from interface: SnapshotGenerator

Inquire if this SnapshotGenerator is capable of snapshotting objects of type objectType (e.g. Table, Index, View etc.) in the DBMS database (e.g. Oracle, Postgres, HyperSQL etc.) A return priority of > 0 will be interpreted as capable. The highest priority for an objectType-database combination wins.

Specified by:

getPriority in interface SnapshotGenerator

Overrides:

getPriority in class UniqueConstraintSnapshotGenerator

Parameters:

objectType - The object type we are asked to snapshot

database - The DBMS for which the snapshotting should be done

Returns:

An integer of PRIORITY_... constants indicating our capability and willingness to snapshot

replaces

public Class<? extends SnapshotGenerator>[] replaces()

Description copied from interface: SnapshotGenerator

Returns classes (and superclasses) that this SnapshotGenerator replaces. Return null or empty array to not affect the SnapshotGeneratorChain.

Specified by:

replaces in interface SnapshotGenerator

Overrides:

replaces in class JdbcSnapshotGenerator

 DatabaseSnapshot snapshot,
 Schema schema)
                                   throws DatabaseException,
SQLException

Overrides:

listConstraints in class UniqueConstraintSnapshotGenerator

Throws:

SQLException

listColumns

protected List<Map<String,?>> listColumns(UniqueConstraint example,
 Database database,
 DatabaseSnapshot snapshot)
                                   throws DatabaseException

Overrides:

listColumns in class UniqueConstraintSnapshotGenerator

Throws:

DatabaseException
