Create a Message Builder Step

When editing a transformer, you can create a Message Builder Transformer Step directly from the message tree. Method 1: Right-click the node you want to modify, then select Map to Message. A dialog may be shown asking whether you want to add the step as part of an Iterator. For additional information, see Working With Iterators. A Message Builder is automatically added to the table with the selected node populated appropriately. Method 2 Drag the node you wish to map from the inbound message tree, and drop it into the node you wish to map to in the outbound message tree. The same steps follow as in Method 1.

Transformer Tasks

The following context-specific tasks are available throughout the Edit Transformer View: Task Icon Task Name Description Add New Step Adds a new transformer step to the table. If an Iterator step or any step that is a child of an Iterator is currently selected, the new step is placed at the end of the children of the most immediate parent Iterator. Otherwise, the new step will be placed at the very end of the list at the bottom of the table. Delete Step Removes the currently selected step from the table. If an Iterator step is deleted, all of its children are also deleted. Assign To Iterator Adds the selected step to a new or existing Iterator. For additional information, see Working With Iterators. Remove From Iterator Removes the selected step from its current Iterator. For additional information: Working With Iterators Import Transformer Imports a transformer from an XML file. You can choose to completely replace the current transformer, or simply append the steps to the current tab

Rule/Step Table

The table in the top half of the Edit Filter / Transformer Views shows all the rules/steps you currently have configured. If you have Iterators, the elements are organized into a tree-table with the children underneath each Iterator. Column Description Enabled Determines whether the rule/step is currently enabled. When disabled, rules/steps are not executed at all, and act as if they were never there in the first place. For filters, this could change behavior as it follows the AND/OR order of operations. When all rules in a filter are disabled, the filter acts as if no rules exist, and is not executed at all. # This is the sequence number of the rule / step, starting at 0 for the first one. For child elements underneath an Iterator, this will be multiple numbers separated by a dash, to indicate the child index of each depth level. Name This is the name of the rule / step. If the type of rule / step allows user editing, you can double-click the cell to edit the name. For filter rules, y

Iterator Filter Rule

This is a special type of rule that allows you to decide whether to filter a message or not by iterating through an array or list of XML nodes. The child rules underneath the Iterator determine the accept/filter behavior of the overall rule. For additional information, see Working With Iterators. Item Name Description Iterate On The element to iterate on. This may be a list of E4X XML nodes, or a Java / JavaScript array. Index Variable The index variable to use for each iteration. Accept Message If Determines how to logically combine each iteration into the overall accept / filter behavior. At Least One: If the logical combination of the child rules returns true for at least one of the iterations, the overall Iterator behavior will be to accept the message. All: If the logical combination of the child rules returns true for all of the iterations, the overall Iterator behavior will be to accept the message. Break Early If this is enabled, the iterator loop will terminate as quickly as p

Iterator Transformer Step

This is a special type of step that allows you to perform extract / transform operations while iterating through an array or list of XML nodes. For additional information, see Working With Iterators . Item Name Description Iterate On The element to iterate on. This may be a list of E4X XML nodes, or a Java / JavaScript array. Index Variable The index variable to use for each iteration. Drag-and-Drop Substitutions When drag-and-dropping values into the children underneath this Iterator, the index variable (e.g. "[i]") will be injected after any of these prefixes. For example if your index variable is i and you have msg['PID'] in the Drag-and-Drop Substitutions table, when you drag the value msg['PID']['PID.3']['PID.3.1'].toString() from the Message Trees Tab into a child step, it will automatically be replaced with msg['PID'][i]['PID.3']['PID.3.1'].toString().
