Prototype

	procedure NhlUpdateData (
		dcomms [*] : graphic   
	)

Arguments

An array of ids of the DataComm classes to be updated.

Description

This procedure forces the DataComm instances to update their internal states to reflect any changes that have occurred in the DataItem instances that have been associated with the DataComm instances.

This procedure is really only useful when the items in dcomms have the resource dcDelayCompute set to True. When this is True, DataComm instances are not notified of changes to their data items. This procedure tells each object in dcomms to check for changes in its data. These data were added with the NhlAddData or added using create or setvalues.
