Method Detail

providerOpened

void providerOpened(DBObjectProvider provider)

Notifies the listener that the provider has been opened or initialised.

providerReloaded

void providerReloaded(DBObjectProvider provider)

Notifies the listener that the provider has been reloaded or restarted.

providerClosed

void providerClosed(DBObjectProvider provider)

Notifies the listener that the provider has been closed or disconnected.

providerDeleted

void providerDeleted(DBObjectProvider provider)

Notifies the listener that the provider has been deleted. This is different to closed because this means the definition for this provider no longer exists.

schemaAdded

void schemaAdded(DBObjectProvider provider,
                 Schema schema)

Notifies the listener that a Schema has been added to the provider.

schemaRemoved

void schemaRemoved(DBObjectProvider provider,
                   Schema schema)

Notifies the listener that a Schema has been removed from the provider.

See Also:

Schema

schemaUpdated

void schemaUpdated(DBObjectProvider provider,
                   DBObjectChange change)

Notifies the listener that a Schema has been updated. This is for properties of the actual schema - not for changes to any objects contained within the schema (Tables, Views etc). To listen for such changes use a SchemaObjectListener and attach to the appropriate SchemaObject.

schemaObjectsAdded

void schemaObjectsAdded(DBObjectProvider provider,
                        Schema schema,
                        SchemaObject[] objs)

Notifies the listener that SchemaObjects have been added to the provider.

See Also:

SchemaObject

schemaObjectsRemoved

void schemaObjectsRemoved(DBObjectProvider provider,
                          Schema schema,
                          SchemaObject[] objs)

Notifies the listener that the given SchemaObjects have been removed from the provider. Note that if an object is moved from one schema to another then a schemaObjectsRemoved followed by a schemaObjectsAdded event is fired. When the removed event is fired the schema set on the SchemaObjects will not match the schema passed into this method, and therefore the listener can identify that those objects are being moved to another schema, rather than deleted.

Parameters:

provider - the provider the event is happening within

schema - the schema the objects are being removed from

objs - the objects being removed. if the schema on any of these objects is different to the schema parameter, that object is being moved to the different schema (rather than deleted).
