Interface DataDictionary

public interface DataDictionary

The DataDictionary interface is used with the data dictionary to get descriptors for binding and compilation. Some descriptors (such as table and column descriptors) are added to and deleted from the data dictionary by other modules (like the object store). Other descriptors are added and deleted by the language module itself (e.g. the language module adds and deletes views, because views are too high-level for modules like the object store to know about).

Version:: 0.1

                 throws org.apache.derby.iapi.error.StandardException

Inform this DataDictionary that we are about to start reading it. This means using the various get methods in the DataDictionary. Generally, this is done during query compilation.

doneReading

public void doneReading(int mode,
                        org.apache.derby.iapi.sql.conn.LanguageConnectionContext lcc)
                 throws org.apache.derby.iapi.error.StandardException

Inform this DataDictionary that we have finished reading it. This typically happens at the end of compilation.

startWriting

public void startWriting(org.apache.derby.iapi.sql.conn.LanguageConnectionContext lcc)
                  throws org.apache.derby.iapi.error.StandardException

Inform this DataDictionary that we are about to start writing to it. This means using the various add and drop methods in the DataDictionary. Generally, this is done during execution of DDL.
