Detailed Description

IObjectManager Class Definition.

Interface for the ObjectManager family. An ObjectManager acts as a gateway between the actual database and the ManagedObject. It also provides subscribing services for the observers.

Member Function Documentation

virtual void* IObjectManager::findNode (  const char *    nodeID, void *    inRoot )  [pure virtual]

Returns the node with the specified ID searching from the specified root Parameters: nodeID  Name of the data node to look for inRoot  Root from which to start searching Implemented in ObjectManager.

virtual WDError IObjectManager::getAttribute (  void *    inNode, const char *    inAttribute, char *    outValue, int    inMaxLength )  [pure virtual]

Returns an attribute of the specified data node Parameters: inNode  The data node on which to perform the operation inAttribute  The attribute to get outValue  The value of the attribute inMaxLength  The size of the character buffer Implemented in ObjectManager.

virtual void* IObjectManager::getChild (  void *    inNode, int    inIndex )  [pure virtual]

Returns the child of the specified node at the specified index. Parameters: inNode  The data node whose child is requested inIndex  The index of the child requested Implemented in ObjectManager.

virtual int IObjectManager::getChildCount (  void *    inNode )  [pure virtual]

Returns the number of child associated with the data node Parameters: inNode  The data node on which to perform the operation Implemented in ObjectManager.

virtual int IObjectManager::getIndex (  void *    inNode )  [pure virtual]

Returns the index of the data node with regard to its parent Parameters: inNode  The data node on which to perform the operation Implemented in ObjectManager.

virtual void* IObjectManager::getParentNode (  void *    inNode )  [pure virtual]

Returns the parent of the specified data node Parameters: inNode  The data node whose parent is requested Implemented in ObjectManager.

virtual void* IObjectManager::getRoot (    )  [pure virtual]

Returns the root of the database Implemented in ObjectManager.

virtual void IObjectManager::getType (  void *    inNode, char *    outType, int    inMaxLength )  [pure virtual]

Returns the type of the specified data node Parameters: inNode  The data node whose type is requested outType  The type of the specified node inMaxLength  The size of the character buffer. Implemented in ObjectManager.

virtual void* IObjectManager::newChildNode (  const char *    inType, void *    inParent )  [pure virtual]

Creates a new node in the database Parameters: inType  Type of the node to create inParent  Parent of the node to create Implemented in ObjectManager.

virtual void IObjectManager::notifyChanged (  void *    inNode )  [pure virtual]

Notifies the observers that the data node has changed Parameters: inNode  The node that changed Implemented in ObjectManager.

virtual void IObjectManager::notifyChildAdded (  void *    inStartNode, void *    inChildNode )  [pure virtual]

Notifies the observers that a child was added to the node or to a child of the node Parameters: inStartNode  The first parent to be notified inChildNode  The child which changed Implemented in ObjectManager.

virtual void IObjectManager::notifyChildChanged (  void *    inStartNode, void *    inChildNode )  [pure virtual]

Notifies the observers that a child to the node or to a child of the node has changed Parameters: inStartNode  The first parent to be notified inChildNode  The child which changed Implemented in ObjectManager.

virtual void IObjectManager::registerObject (  void *    inObject )  [pure virtual]

Temporary hack - we need to have at least one ManagedObject of for each node loaded in memory all the time - and I don't feel like telling you why. Go ask Etienne instead... Implemented in ObjectManager.

virtual void IObjectManager::release (  IManagedObject *    inObject )  [pure virtual]

Removes an IManagedObject from the subscriber list Parameters: inObject  The object to remove the the subscribing list Implemented in ObjectManager.

virtual WDError IObjectManager::saveToFile (  const char *    inFileName )  [pure virtual]

Saves the database to a file Parameters: inFileName  Name of the file Note: If a file already exists with the same name, it will be overwritten Implemented in ObjectManager.

virtual WDError IObjectManager::setAttribute (  void *    inNode, const char *    inAttribute, const char *    inValue )  [pure virtual]

Sets an attribute of the specified data node Parameters: inNode  The data node on which to perform the operation inAttribute  The attribute to set inValue  The value at which the attribute should be set Implemented in ObjectManager.

virtual WDError IObjectManager::subscribe (  IManagedObject *    inObject, void *    inTargetNode )  [pure virtual]

Subscribes the observer to the data node Parameters: inObject  The data node inTargetNode  The observer Implemented in ObjectManager.
