LoadFromBag()

bool LoadFromBag	(	INodeMap *	pNodeMap,
		bool	Verify = true,
		GENICAM_NAMESPACE::gcstring_vector *	pErrorList = NULL
	)

Loads the features from the bag to the node tree

Parameters

pNodeMap	The node map to load into
Verify	If true, all streamable features are read back
pErrorList	If an error occurs during loading the error message is stored in the list and the loading continues

For Verify=true the list of names in the feature bag is replayed again. If a node is a selector it's value is set to the value from the feature bag If not the value is read from the camera and compared with the value from the feature bag.

StoreToBag()

int64_t StoreToBag	(	INodeMap *	pNodeMap,
		const int	MaxNumPersistSkriptEntries = -1,
		GENICAM_NAMESPACE::gcstring_vector *	pFeatureFilter = NULL
	)

Parameters

pNodeMap	The node map to persist
MaxNumPersistSkriptEntries	The max number of entries in the container; -1 means unlimited
pFeatureFilter	List of valid feature; all feature if NULL.

Returns

number of entries in the bag
