Developing OTDs for Application Adapters

Non-Root Methods

Every leaf node in a COBOL Copybook OTD represents an elementary item in the Copybook source. For every given leaf node, the OTD provides “getter” and “setter” methods of which the return type and input types depend on the data type and usage type specified in the copybook for the elementary item to which the node corresponds.

For a given non-repeating leaf node named Datum, the following method forms are provided, where T is determined from the follow table.

For repeating leaf nodes, these two alternative methods are provided:

where i is expected to be a value from 0, representing the ordinal of the desired repetition instance, and where T is determined as previously described.
