Iterator Transformer Step

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().

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

Creating Iterators From Drag-and-Drop

As explained in the Message Trees Tab section, new rules and steps can be created by right-clicking the node in the message tree, by dragging a node into the filter/transformer table, or by dragging a node from the inbound tree and dropping it onto a node in the outbound tree. In all of these cases, you will be presented with a prompt asking whether you want to create an Iterator automatically. If Yes is chosen, the Iterator Wizard dialog is shown. In this wizard dialog you can select your iteration target (what to iterate on). If you have dragged from inbound to the outbound template, you will also have the option to select which part of the outbound (tmp) expression corresponds to the inbound (msg) target being iterated on. These options correspond directly to the drag-and-drop substitutions shown at the bottom of the dialog. You are essentially telling the wizard "where the i goes" Once you select OK, the Iterator and subsequent rule/step will be created. So far it is only iterating

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

Create a Rule Builder Rule or Mapper Step

When editing a filter, you can create a Rule Builder Filter Rule directly from the message tree. When editing a transformer, you can create a Mapper Transformer Step in the same way. Method 1 Right-click the node you wish to filter on or map, then select either Filter by Value or Map to Variable: A dialog may be shown asking whether you want to add the rule/step as part of an Iterator. For additional information, see Working With Iterators A Rule Builder or Mapper is automatically added to the table with the selected node populated appropriately. Method 2 Drag the node you wish to filter on or map from the tree into the table. The same steps follow as in Method 1. Parent topic: Message Trees 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

Create New Rules/Steps

As outlined in the Message Trees Tab section, new rules / steps can be generated easily from the inbound/outbound message trees. They can also be created manually. Select the Add New Rule/Step task to the left: A new rule/step is created and added to the table. To change the type of rule/step, double-click the cell in the Type column. To change the name, double-click the cell in the Name column. Some rule/step types have names auto-generated from the properties and so do not allow editing in the table. If you are creating a filter rule, you can change the operator of the rule by selecting the AND or OR button next to the name. Parent topic: Edit Filter / Transformer Views
