| gcp::Operation::Operation | ( | Document * | pDoc, | |
| unsigned long | ID | |||
| ) |
| pDoc | a document. | |
| ID | a unique operation ID for the document and the session. |
| void gcp::Operation::Add | ( | unsigned | type = 0 |
) | [protected] |
| type | a number indicationg the role of the stored objects. |
Adds the stored objects to the document owning the operation.
| virtual void gcp::Operation::AddNode | ( | xmlNodePtr | node, | |
| unsigned | type = 0 | |||
| ) | [virtual] |
| node | an xml node related to the changes. | |
| type | a number indicationg the role of the stored objects. |
Adds the node to the document owning the operation. This might be used when Objects are not available such as when editing text.
| virtual void gcp::Operation::AddObject | ( | gcu::Object * | pObject, | |
| unsigned | type = 0 | |||
| ) | [virtual] |
| pObject | an Object affected by the changes. | |
| type | a number indicationg the role of the stored objects. |
Adds an object to the operation. Typically, modifying an object whould need code like:
Object *obj;
// Initialize the object pointer so that it points to a valid object
...
Document *doc = obj->GetDocument ();
Operation *op = doc->GetNewOperation (GCP_MODIFY_OPERATION);
op->AddObject (obj, 0);
// Modify the object
...
op->AddObject (obj, 1);
doc->FinishOperation ();
| void gcp::Operation::Delete | ( | unsigned | type = 0 |
) | [protected] |
| type | a number indicationg the role of the stored objects. |
Deletes the stored objects to the document owning the operation.
| virtual void gcp::Operation::Redo | ( | ) | [pure virtual] |
Redo the changes represented by this operation.
Implemented in gcp::AddOperation, gcp::DeleteOperation, and gcp::ModifyOperation.
| virtual void gcp::Operation::Undo | ( | ) | [pure virtual] |
Undo the changes represented by this operation.
Implemented in gcp::AddOperation, gcp::DeleteOperation, and gcp::ModifyOperation.
xmlNodePtr* gcp::Operation::m_Nodes [protected] |
The xml nodes storing the changes.
