Description
The DataItem class is used as a building block for all the
objects that describe data to the HLU library. There are no actual data
description resources or anything in this class accessible to the application
programmer. This class is the basis for all the classes that do describe
data. It understands how to communicate with the DataComm
class so that the actual data description objects can share that functionality.
Support functions
Some of the support functions for the
DataComm class
are intended to be used with DataItem class objects.
Additionally, the DataItem class defines the following
function:
-
NhlIsDataItem
-
This function just determines if a given object id identifies a
DataItem class object.
