Specifying the Node Type (Developing OTDs for Communication Adapters)

Developing OTDs for Communication Adapters

Specifying the Node Type

Click on the nodeType properties field to activate the field for editing. Click the arrow button to display the selection menu. Descriptions of the property options are listed in the table.

Node Type Property Options
Option	Description	Element	Field	Internal
array	Array is a delimited structure. If repeated, occurrences are separated by the repeat delimiter. The last occurrence may be terminated by a normal delimiter.	Yes	Yes	simple or group
delim	Delim (delimited) structure. If repeated, occurrences are separated by a normal delimiter.	Yes	Yes	simple or group
fixed	Fixed indicates a fixed length, which is specified by non-negative integer (or zero to indicate end of parent node data).	Yes	Yes	simple or group
group	Group provides organizational grouping for purposes such as repetition. Applies only to elements.	Yes	No	group
trans	Trans (transient) appears only in an internal tree as a scratch pad field. It does not appear in external data representation, and can only have trans nodeTypes as children.	Yes	Yes	choice, simple, or group

Note –

If you move an OTD node, you must reset the nodeType for that node.

Node Management

The OTD Editor allows you to:

Add nodes and elements to an OTD.
Delete nodes and elements from an OTD.

When a node is deleted, both the node and its associated children (data elements) are deleted.
Prune nodes in an OTD.

When a node is pruned, only its associated children (data elements) are deleted, while the node itself is preserved. Pruning can only be performed on nodes.

These commands are accessed from the node context menu.
