Constructor Detail

DictionaryDatabase

protected DictionaryDatabase(java.lang.String connStore,
                             java.lang.String connName,
                             java.sql.Connection conn)

Method Detail

newQueryWrapper

protected final QueryWrapper newQueryWrapper(java.lang.String query,
                                             java.lang.Object... params)

newQueryWrapper

protected QueryWrapper newQueryWrapper(java.lang.String query,
                                       java.util.List params)

getDictionaryQueries

protected abstract DictionaryQueries getDictionaryQueries()

isSupportedType

protected boolean isSupportedType(java.lang.String type)

supportsTimestamps

public boolean supportsTimestamps(java.lang.String objectType)

Returns true if this database supports timestamping. By default this will return true if either the by ID or by name (for tables) timestamp queries are non-null. Override if appropraite.

Overrides:

supportsTimestamps in class AbstractDBObjectProvider

getListQueries

protected QueryWrapper[] getListQueries(DBObjectCriteria<? extends SystemObject> criteria)

Retruns a number of query wrapper objects that will list the given object types in the given schema.

Ideally this method would only return one query wrapper as that will most probably be more efficient in getting the data. However where a Database implementation is unable to UNION the list queries together it can return multiple wrappers.

createID

public final DBObjectID createID(Schema schema,
                                 java.lang.String name,
                                 java.lang.String type,
                                 java.lang.Object id)

listObjectsImpl

protected <T extends SystemObject> java.util.Collection<T> listObjectsImpl(DBObjectCriteria<T> criteria)
                                                                throws DBException

Description copied from class: AbstractDBObjectProvider

Internal listObjects implementation. All listObjects methods call through to this.

Specified by:

listObjectsImpl in class AbstractDBObjectProvider

Throws:

DBException

                                                               java.lang.String[] typeList)
