Method Detail

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 JdbcSnapshotGenerator

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

snapshotObject

protected DatabaseObject snapshotObject(DatabaseObject example,
                                        DatabaseSnapshot snapshot)
                                 throws DatabaseException

Specified by:

snapshotObject in class JdbcSnapshotGenerator

Throws:

DatabaseException

addTo

protected void addTo(DatabaseObject foundObject,
                     DatabaseSnapshot snapshot)
              throws DatabaseException

Specified by:

addTo in class JdbcSnapshotGenerator

Throws:

DatabaseException

listConstraints

protected List<CachedRow> listConstraints(Table table,
                                          DatabaseSnapshot snapshot,
                                          Schema schema)
                                   throws DatabaseException,
                                          SQLException

Throws:

DatabaseException

SQLException

listColumns

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

Throws:

DatabaseException

supportsBulkQuery

protected boolean supportsBulkQuery(Database database)

To support bulk query, the resultSet must include a CONSTRAINT_CONTAINER column for caching purposes
