Contexts (SAP Library - SAP Exchange Infrastructure (BC-XI))

Contexts

When the instance for the source structure is parsed, a message mapping works internally by using queues.

This graphic is explained in the accompanying text

If no further elements are imported at a particular hierarchy level, a Context Change is inserted in the queue. Therefore, in the example above elements 2 and 3 belong to a context. By inserting and removing context (changes) you can use this internal representation for creating special structure mappings.

To delete all context changes of a queue, simply delete the relevant hierarchy level. Example: If you delete the context for the queue for the element <item>, the top node element <A> is ignored and a list is outputted. Also see: removeContexts

You can insert additional context changes independently of the values in a queue, for example after each value. In doing so, you insert a new hierarchy level. Also see: SplitByValue
