Detailed Description

Provides a node that serves as a data input into a node graph.

Constructor & Destructor Documentation

◆ GraphInputNode()

GraphModel::GraphInputNode::GraphInputNode ( GraphModel::GraphPtr  graph,
DataTypePtr  dataType 
)

Constructor

Parameters
graphThe graph that owns this node
dataTypeThe type of data represented by this node

Member Function Documentation

◆ GetDefaultValue()

AZStd::any GraphModel::GraphInputNode::GetDefaultValue ( ) const

Returns the value of the DefaultValue slot, which indicates the default value for this input. This is the value that will be used when this node's graph is used as a ModuleNode, but no data is connected to this graph input.

◆ PostLoadSetup()

void GraphModel::GraphInputNode::PostLoadSetup ( GraphPtr  graph,
NodeId  id 
)
overridevirtual

Initializion after the Node has been serialized in. This must be called whenever the default constructor is used. Sets the m_graph pointer and caches pointers to other GraphElements. It also ensures the loaded Slot data aligns with the defined SlotDefinitions.

Reimplemented from GraphModel::Node.
