Transition objects
There are three tags in the configuration file of transition objects:
▪ <appearance> tag
▪ <properties> tag
▪ <property> tag
An example of a configuration file for a transition object is provided here:
<transition xmlns="http://btt.ibm.com/TransitionSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://btt.ibm.com/TransitionSchema TransitionSchema.xsd ">
<appearance lineColor="0,0,0" lineWidth="1" lineStyle="Solid" arrowTypeStyle="SolidArrow" font="Arial-regular-10" fontColor="0,0,0" />
<properties>
<property name="Event" hidden="false" required="true" defaultValue="" editRule="EventTransitionBeta"/>
<property name="Input Data Format" required="false" description="%InputFormat" editRule="MapperFormat"/>
<property name="Output Data Format" required="false" description="%OutputFormat" editRule="MapperFormat"/>
<property name="Skip Validation" defaultValue="false" description="%TransValidated" editRule="Boolean"/>
<property name="id" defaultValue="" hidden="true" required="false" />
</properties>
</transition>
The <appearance> tag defines how a transition object is displayed in the Palette view in Rational Application Developer and in the editing area of the Processor editor.
