Creating a Configuration Plug-in

To create a configuration plug-in:

1. Use the PTEM_CONFIG application package to create a plug-in. If you need to use a custom package, ensure that the custom package starts with PTEM_CONFIG.

2. Write the plug-in class. The new plug-in class must extend from the base class — PTEM_CONFIG:EMConfigurationPlugin.

   Override and implement the four base class methods:

   • getProperties - to provide plug-in properties and their details.

     For example:

     method getProperties
        /+ Returns Array of PTEM_CONFIG:PTEMVariableProperty +/
        /+ Extends/implements PTEM_CONFIG:EMConfigurationPlugin.getProperties +/
     
        Local array of PTEM_CONFIG:PTEMVariableProperty &propArray = Null;
     
     ---add the properties as shown below---------------
         &variableProperty = create PTEM_CONFIG:PTEMVariableProperty("property_name", "datatype", True/False (is required?), True/False(is password?), "default value", Message set number of property description, message number, "default message", Null);   &propArray.Push(&variableProperty);  ---------------------------------------------------------------------------------------------------- 
        Return &propArray;
     end-method;

     Add the following base class methods:

     • validateVariables - to validate the plug-in property values.

     • configureEnvironment - to configure the environment with the provided values.

     • validateConfigurations - to validate whether the values are correctly configured.

   • dependant_plugins - to provide the names of dependent plug-ins.

     For example:

     method dependant_plugins
        /+ Returns Array of String +/
        /+ Extends/implements PTEM_CONFIG:EMConfigurationPlugin.dependant_plugins +/
        Local array of string &dependant_array;
        &dependant_array = CreateArray(""); -----add the plugins as comma seprated values, that this plugin depends on for its execution
        Return &dependant_array;
     end-method;

   • getPluginHelpMessage - to provide a brief description of a plug-in.

     For example:

     method getPluginHelpMessage
        /+ Returns PTEM_CONFIG:PTEMHelpMessage +/
        /+ Extends/implements PTEM_CONFIG:EMConfigurationPlugin.getPluginHelpMessage +/
        Local PTEM_CONFIG:PTEMHelpMessage &tempMessage = Null;
        &tempMessage = create PTEM_CONFIG:PTEMHelpMessage(0, 0, "", Null);   ---- "add the message set number, message number and default message of the help message"
        Return &tempMessage;
     end-method;

   • isInternalPlugin - to differentiate between plug-ins that can be used internally by developers and externally by customers.

     Valid values are:

     • False - specifies that the plug-in can be used by customers, and the plug-in can be added in a template in PIA.

     • True - implies that the plug-in can be used only through command line and will not be available in PIA.

     For example:

     method isInternalPlugin
        /+ Returns Boolean +/
        /+ Extends/implements PTEM_CONFIG:EMConfigurationPlugin.isInternalPlugin +/
        Return False;
     end-method;

Note:

When you create a configuration plug-in an application package, the plug-in must be registered through the automated configuration management framework so that it can be included in a template for configuration through PIA. If a plug-in is not registered, it can be used only for execution through command line.
