Modifier and Type	Method and Description
protected boolean	canChangeSchema() By default an object's schema can be changed (only applies to SchemaObjects).
CascadeAction	cascadeDelete(DBObject removed, T obj) Cascade deletes the given removed object.
protected CascadeAction	cascadePropertyChange(Difference objDiff, java.lang.String propName, java.lang.Object oldValue, java.lang.Object newValue, T obj) Process the given difference from a dependent object that is being updated.
protected boolean	checkSchemaDelete(DBObject removed, T obj) Checks whether the removed object is the Schema for the given SchemaObject.
protected boolean	checkSchemaRename(Difference objDiff, java.lang.String propName, T obj) Checks the given object objDiff and propertyName and if they represent a schema rename for the Schema of the given object then we update obj with the new schema and return true.

Method Detail

validateSchema

public void validateSchema(T original,
                  T updated)
                    throws ValidationException

Throws:

ValidationException

canChangeSchema

protected boolean canChangeSchema()

By default an object's schema can be changed (only applies to SchemaObjects).

cascadeDelete

public CascadeAction cascadeDelete(DBObject removed,
                          T obj)

Description copied from class: CascadeWorker

Cascade deletes the given removed object. Possible rreturn values are:

• NONE no action was required
• UPDATE obj has been updated appropriate
• DELETE obj should be deleted

Overrides:

cascadeDelete in class CascadeWorker<T extends SchemaObject>

Parameters:

removed - the object that we are cascading the delete of

obj - the object to cascade to

Returns:

the appropriate cascade action

checkSchemaDelete

protected boolean checkSchemaDelete(DBObject removed,
                        T obj)

Checks whether the removed object is the Schema for the given SchemaObject.

Parameters:

removed - the object being removed

obj - the SchemaObject that we're cascading to

Returns:

true if the object is in the removed schema (and should therefore be deleted).

cascadePropertyChange

protected CascadeAction cascadePropertyChange(Difference objDiff,
                                  java.lang.String propName,
                                  java.lang.Object oldValue,
                                  java.lang.Object newValue,
                                  T obj)

Description copied from class: CascadeWorker

Process the given difference from a dependent object that is being updated. This does not need to recurse into the given difference if it is a DBObject, that wil be done by the framework.

Overrides:

cascadePropertyChange in class CascadeWorker<T extends SchemaObject>

Parameters:

objDiff - the full difference for the updated object

propName - the name of the changed property we are cascading

oldValue - the old property value

newValue - the new property value

obj - the object to cascade the change to

Returns:

a CascadeAction appropriate to any change made or required. If UPDATE is returned any appropriate change should have been made to obj.

checkSchemaRename

protected boolean checkSchemaRename(Difference objDiff,
                        java.lang.String propName,
                        T obj)

Checks the given object objDiff and propertyName and if they represent a schema rename for the Schema of the given object then we update obj with the new schema and return true.

Parameters:

objDiff - the DBObject difference we're cascadding

propName - the property that has been changed

obj - the object to cascade the change to

Returns:

true if propName is "name" and objDiff contains the object's schema (and we therefore cascade the rename to obj).
