Member Data Documentation

OnNodeAdded

XnStatus(*) XnNodeNotifications::OnNodeAdded(void *pCookie, const XnChar *strNodeName, XnProductionNodeType type, XnCodecID compression)

Notifies the object that a production node was added

Parameters

pCookie	[in] A cookie that was received with this interface.
strNodeName	[in] The instance name of the added node.

OnNodeGeneralPropChanged

XnStatus(*) XnNodeNotifications::OnNodeGeneralPropChanged(void *pCookie, const XnChar *strNodeName, const XnChar *strPropName, XnUInt32 nBufferSize, const void *pBuffer)

Notifies the object that a general type property has changed.

Parameters

pCookie	[in] A cookie that was received with this interface.
strNodeName	[in] The name of the node whose property changed.
strPropName	[in] The name of the property that changed.
nBufferSize	[in] The size of the buffer that holds the new value.
pBuffer	[in] The buffer that holds the new value of the property.

OnNodeIntPropChanged

XnStatus(*) XnNodeNotifications::OnNodeIntPropChanged(void *pCookie, const XnChar *strNodeName, const XnChar *strPropName, XnUInt64 nValue)

Notifies the object that an integer type property has changed.

Parameters

pCookie	[in] A cookie that was received with this interface.
strNodeName	[in] The name of the node whose property changed.
strPropName	[in] The name of the property that changed.
nValue	[in] The new value of the property.

OnNodeNewData

XnStatus(*) XnNodeNotifications::OnNodeNewData(void *pCookie, const XnChar *strNodeName, XnUInt64 nTimeStamp, XnUInt32 nFrame, const void *pData, XnUInt32 nSize)

Notifies the object that it has received new data.

Parameters

pCookie	[in] A cookie that was received with this interface.
strNodeName	[in] The name of the node whose property changed.
strName	[in] The name of the property that changed.
nBufferSize	[in] The size of the buffer that holds the new value.
pBuffer	[in] The buffer that holds the new value of the property.

OnNodeRealPropChanged

XnStatus(*) XnNodeNotifications::OnNodeRealPropChanged(void *pCookie, const XnChar *strNodeName, const XnChar *strPropName, XnDouble dValue)

Notifies the object that a real type property has changed.

Parameters

pCookie	[in] A cookie that was received with this interface.
strNodeName	[in] The name of the node whose property changed.
strPropName	[in] The name of the property that changed.
dValue	[in] The new value of the property.

OnNodeRemoved

XnStatus(*) XnNodeNotifications::OnNodeRemoved(void *pCookie, const XnChar *strNodeName)

Notifies the object that a production node has been removed

Parameters

pCookie	[in] A cookie that was received with this interface.
strNodeName	[in] The instance name of the removed node.

OnNodeStateReady

XnStatus(*) XnNodeNotifications::OnNodeStateReady(void *pCookie, const XnChar *strNodeName)

Notifies the object that a node has finished sending all the initial 'property changed' notifications.

Parameters

pCookie	[in] A cookie that was received with this interface.
strNodeName	[in] The name of the node whose state is ready.

OnNodeStringPropChanged

XnStatus(*) XnNodeNotifications::OnNodeStringPropChanged(void *pCookie, const XnChar *strNodeName, const XnChar *strPropName, const XnChar *strValue)

Notifies the object that a string type property has changed.

Parameters

pCookie	[in] A cookie that was received with this interface.
strNodeName	[in] The name of the node whose property changed.
strPropName	[in] The name of the property that changed.
strValue	[in] The new value of the property.
