Constructor Detail

TableSequenceDefinition

public TableSequenceDefinition(Sequence sequence,
                               boolean deleteSchema)

INTERNAL: Should be a sequence defining table sequence in the db: either TableSequence DefaultSequence (only if case platform.getDefaultSequence() is a TableSequence).

Method Detail

buildCreationWriter

public java.io.Writer buildCreationWriter(org.eclipse.persistence.internal.sessions.AbstractSession session,
                                          java.io.Writer writer)
                                   throws ValidationException

INTERNAL: Return the SQL required to insert the sequence row into the sequence table. Assume that the sequence table exists.

Specified by:

buildCreationWriter in class DatabaseObjectDefinition

Throws:

ValidationException

buildDeletionWriter

public java.io.Writer buildDeletionWriter(org.eclipse.persistence.internal.sessions.AbstractSession session,
                                          java.io.Writer writer)
                                   throws ValidationException

INTERNAL: Return the SQL to delete the row from the sequence table. If we're dealing with create creation, then delegate to the table so that is dropped outright since we will delete the schema.

Specified by:

buildDeletionWriter in class DatabaseObjectDefinition

Throws:

ValidationException

checkIfExist

public boolean checkIfExist(org.eclipse.persistence.internal.sessions.AbstractSession session)
                     throws DatabaseException

INTERAL: Execute the SQL required to insert the sequence row into the sequence table. Assume that the sequence table exists.

Specified by:

checkIfExist in class SequenceDefinition

Throws:

DatabaseException

dropDatabaseSchema

public void dropDatabaseSchema(org.eclipse.persistence.internal.sessions.AbstractSession session,
                               java.io.Writer writer)
                        throws EclipseLinkException

INTERNAL: Execute the DDL to drop the database schema for this object. Does nothing at this level, subclasses that support this must override this method.

Overrides:

dropDatabaseSchema in class DatabaseObjectDefinition

Throws:

EclipseLinkException

See Also:

TableDefinition

dropDatabaseSchemaOnDatabase

public void dropDatabaseSchemaOnDatabase(org.eclipse.persistence.internal.sessions.AbstractSession session)
                                  throws EclipseLinkException

INTERNAL: Execute the DDL to drop the database schema for this object. Does nothing at this level, subclasses that support this must override this method.

Overrides:

dropDatabaseSchemaOnDatabase in class DatabaseObjectDefinition

Throws:

EclipseLinkException

Execute any statements required before the deletion of the object

Overrides:

preDropObject in class DatabaseObjectDefinition

Parameters:
