Defining the components configuration in btt.xml file

Runtime components : Core components : Initialization manager : Tasks : Defining the components configuration in btt.xml file

The file btt.xml is the configuration file for all the UNICOM^® Digital Transformation Toolkit (UDTT™) components. Following is a sample of btt.xml configuration file:

<?xml version="1.0">
<btt.xml>
  <kColl id="components">
    <kColl id="componentA">
      <field id="initializer" value="mypackage.AInitializer" />
      <field id="attributeA" value+"valueA" />
    </kColl>
    <kColl id="componentB">
      <field id="initializer" value="mypackage.BInitializer" />
      <field id="attributeA" value="valueA" />
    </kColl>
  </kColl>
</btt.xml>

In one UDTT application, you can only have one btt.xml file. When you call InitManager.reset() method, the InitManager performs the following actions:

▪ parses the btt.xml file

▪ finds out the components tag

▪ gets the value of <field id="initializer"/> tag

▪ instantiates the Initializer for the component

▪ calls Initializer.initialize() method

Then the Initializer of the component will get initialized. The InitManager gets all the UDTT components initialized one by one.

Note If you remove the configuration for a component, the component will not be initialized. In this way, you can choose which components to use, and disable the other components.
