IContextNode::GetType method
Retrieves the type of the IContextNode object.
Syntax
HRESULT GetType(
[out] GUID *pContextNodeType
);
Parameters
-
pContextNodeType [out]
-
The type of the IContextNode object.
Return value
For a description of the return values, see Classes and Interfaces - Ink Analysis.
Remarks
Types of nodes are described in the Context Node Types constants.
Examples
The following example shows a helper method that retrieves information about a specified node, its pContextNode parameter. This helper method returns information from the following methods.
- IContextNode::GetId
- IContextNode::GetType
- IContextNode::GetLocation
- IContextNode::GetParentNode
// Helper method for collecting information about a context node.
HRESULT CMyClass::GetNodeInformation(
IContextNode *pContextNode,
GUID *pNodeIdentifier,
GUID *pContextNodeType,
IAnalysisRegion **ppAnalysisRegion,
IContextNode **ppParentNode,
IContextNodes **ppSubNodes)
{
// Get the identifier of the context node.
HRESULT hr = pContextNode->GetId(pNodeIdentifier);
if (FAILED(hr))
{
return hr;
}
// Get the type identifier for the context node.
hr = pContextNode->GetType(pContextNodeType);
if (FAILED(hr))
{
return hr;
}
// Get the location of the context node.
hr = pContextNode->GetLocation(ppAnalysisRegion);
if (FAILED(hr))
{
return hr;
}
// Get the parent node of the context node.
hr = pContextNode->GetParentNode(ppParentNode);
if (FAILED(hr))
{
if ((*ppAnalysisRegion) != NULL)
{
(*ppAnalysisRegion)->Release();
(*ppAnalysisRegion) = NULL;
}
return hr;
}
// Get the subnodes of the context node.
hr = pContextNode->GetSubNodes(ppSubNodes);
if (FAILED(hr))
{
if (*ppAnalysisRegion)
{
(*ppAnalysisRegion)->Release();
(*ppAnalysisRegion) = NULL;
}
if (*ppParentNode)
{
(*ppParentNode)->Release();
(*ppParentNode) = NULL;
}
return hr;
}
return hr;
}
