Member Data Documentation

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.
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.
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.
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.
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.
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.
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.
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.
