Detailed Description

The ITemplate graph node interface.

A template node stores the Resource::IGraphNode object it was created from, in order to be able to create Graph::IInstance nodes later on, which may directly source their sub-graph from the already existing graph by referencing this template. It is often cumbersome to always have to create an extra graph resource object within a package when it is desired to create multiple instances of a sub-graph. Using nodes implementing this interface, instantiation may also occur like this:

<Template id="myTemplate>
  <Namespace id="{namespaceId}">
     ... put your nodes here ...
  </Namespace>
</Template>
 
<Instance templateId="myTemplate" namespaceId="nmSpc1"/>
<Instance templateId="myTemplate" namespaceId="nmSpc2"/>
<Instance templateId="myTemplate" namespaceId="nmSpc3"/>

Member Function Documentation

GetNodeInterface() [1/2]

virtual INode* Murl::Graph::ITemplate::GetNodeInterface ( )

pure virtual

Get the mutable Graph::INode interface.

This method returns a mutable pointer to the node's Graph::INode interface, to be able to query or modify common node properties such as active state, visibility or ID.

Returns

The mutable Graph::INode interface, or null if not available

GetNodeInterface() [2/2]

virtual const INode* Murl::Graph::ITemplate::GetNodeInterface ( ) const

pure virtual

Get the constant Graph::INode interface.

This method returns a constant pointer to the node's Graph::INode interface, to be able to query common node properties such as active state, visibility or ID.

Returns

The constant Graph::INode interface, or null if not available

SetResourceGraphNode()

virtual Bool Murl::Graph::ITemplate::SetResourceGraphNode ( const Resource::IGraphNode *  node )

pure virtual

Set the resource graph node from which to create template instances.

Parameters

node	The resource graph node.

Returns

true if successful.

GetResourceGraphNode()

virtual const Resource::IGraphNode* Murl::Graph::ITemplate::GetResourceGraphNode ( ) const

pure virtual

Get the resource graph node from which to create template instances.

Returns

The resource graph node.

GetUserParameters()

virtual const IAttributes* Murl::Graph::ITemplate::GetUserParameters ( ) const

pure virtual

Get the set of user-defined template parameters, if any are present.

Returns

The set of parameters, or null if no user-defined parameters are present.
