Detailed Description

The oaChangeRec classes support visitor design pattern interfaces. A visitor design pattern interface uses a dual dispatch technique. Each concrete node in the data structure has an accept method, which provides access to a visitor. The accept method sends a message to the visitor that includes the node's class. The visitor can then execute its behavior for that element.

The oaChangeRecVisitor class is capable of visiting concrete oaChangeRec nodes. A derived visitor must implement a derived interface that accesses the derived change records and provides specific behaviors.

When a change set is exported in the OpenAccess change management system (CMS), the export process uses an oaChangeRecVisitor to traverse the change records in the change set. After visiting a specific change record, the visitor exports the contents in the change record to the external format, which now represents the change.

Member Function Documentation

void oaChangeRecVisitor::endHier (  oaHierChangeRec *    node )  [pure virtual]

A change record visitor is notified when the traversal will begin to ascend out of a hierarchical change record. The endHier function allows the caller to control whether or not to ascend. Parameters: node  A pointer to a concrete node in a hierarchical change record.

oaBoolean oaChangeRecVisitor::startHier (  oaHierChangeRec *    node )  [pure virtual]

A change record visitor is notified when the traversal will begin to descend into a hierarchical change record. The startHier function allows the caller to control whether or not to descend. Parameters: node  A pointer to a concrete node of type hierarchical change record.

void oaChangeRecVisitor::visit (  oaConvertObjectChangeRec *    node )  [pure virtual]

This function provides access to a concrete node in a change record that describes the type conversion an object. Parameters: node  A pointer to a concrete node in a change record that describes the type conversion of an object.

void oaChangeRecVisitor::visit (  oaDestroyObjectChangeRec *    node )  [pure virtual]

This function provides access to an oaDestroyObjectChangeRec node. Parameters: node  A pointer to a concrete node of type change record that describes the destruction of an object.

void oaChangeRecVisitor::visit (  oaCreateObjectChangeRec *    node )  [pure virtual]

This function provides access to an oaCreateObjectChangeRec node. Parameters: node  A pointer to a concrete node of type change record that describes the creation of an object.

virtual void oaChangeRecVisitor::visit (  oaDestroy2DTableRelationshipChangeRec *    node )  [pure virtual]

void oaChangeRecVisitor::visit (  oaDestroy1toNRelationshipChangeRec *    node )  [pure virtual]

This function provides access to an oaDestroy1toNRelationshipChangeRec node. Parameters: node  A pointer to a concrete node of type change record that describes the operation of destroying a 1-to-n relationship.

void oaChangeRecVisitor::visit (  oaDestroy1to1RelationshipChangeRec *    node )  [pure virtual]

This function provides access to an oaDestroy1to1RelationshipChangeRec node. Parameters: node  A pointer to a concrete node of type change record that describes the operation of destroying a 1-to-1 relationship.

virtual void oaChangeRecVisitor::visit (  oaCreate2DTableRelationshipChangeRec *    node )  [pure virtual]

virtual void oaChangeRecVisitor::visit (  oaCreate1toNRelationshipChangeRec *    node )  [pure virtual]

void oaChangeRecVisitor::visit (  oaCreate1to1RelationshipChangeRec *    node )  [pure virtual]

This function provides access to an oaCreate1to1RelationshipChangeRec node. Parameters: node  A pointer to a concrete node of type change record that describes the operation of creating a 1-to-1 relationship.

void oaChangeRecVisitor::visit (  oaUnsetAttributeChangeRec *    node )  [pure virtual]

This function provides access to an oaUnsetAttributeChangeRec node. Parameters: node  A pointer to a concrete node of type change record that describes the operation of unsetting the value of an attribute.

void oaChangeRecVisitor::visit (  oaSetAttributeChangeRec *    node )  [pure virtual]

This function provides access to an oaSetAttributeChangeRec node. Parameters: node  A pointer to a concrete node of type change record that describes the operation of setting the value of an attribute.

void oaChangeRecVisitor::visit (  oaTransientMarkerChangeRec *    node )  [pure virtual]

This function provides access to an oaTransientMarkerChangeRec node. Parameters: node  A pointer to a concrete node of type transient marker change record.

void oaChangeRecVisitor::visit (  oaExportMarkerChangeRec *    node )  [pure virtual]

This function provides access to an oaExportMarkerChangeRec node. Parameters: node  A pointer to a concrete node of type export marker change record.

void oaChangeRecVisitor::visit (  oaHierChangeRec *    node )  [pure virtual]

This function provides access to an oaHierChangeRec node. Parameters: node  A pointer to a concrete node of type hierarchical change record.
