Method Detail

getVersion

public double getVersion()

Description copied from interface: StorageManager

Returns the version of this factory implementation. The factory uses this number to verify whether it can handle storage configuration files that list version requirements.

Specified by:

getVersion in interface StorageManager

Overrides:

getVersion in class DatabaseStorageManager

tablesInheritFields

protected boolean tablesInheritFields()

Description copied from class: DatabaseStorageManager

Returns whether tables inherit fields form parent tables. this determines whether fields that are inherited in mmbase builders are redefined in the database tables.

Overrides:

tablesInheritFields in class DatabaseStorageManager

create

public void create(MMObjectNode node,
                   MMObjectBuilder builder)
            throws StorageException

Adds a node to the passed builder and all its parent builders.

Overrides:

create in class DatabaseStorageManager

Parameters:

node - The node to insert. The node already needs to have a (new) number assigned

builder - the builder to store the node

Throws:

StorageException - if an error occurred during creation

change

public void change(MMObjectNode node,
                   MMObjectBuilder builder)
            throws StorageException

Changes a node in the passed builder and all its parent builders

Overrides:

change in class DatabaseStorageManager

Parameters:

node - The node to change

builder - the builder to change the node in

Throws:

StorageException - if an error occurred during change

delete

public void delete(MMObjectNode node,
                   MMObjectBuilder builder)
            throws StorageException

Deletes a node in the passed builder and all its parent builders.

Overrides:

delete in class DatabaseStorageManager

Parameters:

node - The node to delete

builder - the builder to delete the node in
