Input/Output

Parameters

The CA Process Automation parameters to pass to the main method. Enter the parameters in the order that they are to be passed to the main method. Leave this field blank if no parameters are required.

Only simple CA Process Automation parameter types can be passed to the main method as follows:

• PAM Boolean is passed as a Boolean object.
• PAM Date is passed as a Date object.
• PAM Double is passed as a Double object
• PAM Integer is passed as an Integer object.
• PAM Long is passed as a Long object.
• PAM String is passed as a String object.
• PAM Object Reference is passed as a String object
• PAM JavaObject is deserialized and loaded into a Java object instance of its original class type, and then passed to the Java code.

Note: The operator (or operator category) must contain the path to the JAR file that contains the class definition of this object. Otherwise, the operator fails with the reason:

Class Not Found Error when deserializing object. Make sure the class jar is in the operator or module list of jars.

Complex CA Process Automation parameters types (indexed types, ValueMaps, and so on) cannot be passed to the Java code.

The main method can access the passed parameters through the args array of objects:

• args[0] corresponds to the first parameter in the list.
• args[1] corresponds to the second parameter in the list, and so on.

Output Variable Names

The names of the variables that are saved in the operator dataset at the end of execution of the main method. These variables must be defined in the scope of the main method. Leave this field blank if no output variables are to be saved in the operator dataset.

The output variables are saved as follows:

• Boolean object is saved as a PAM Boolean
• Date object is saved as a PAM Date
• Integer object is saved as a PAM Integer
• Number object is saved as PAM Long or Double object
• String object is saved as PAM string
• Character object is saved as PAM string
• An array of any of these listed objects is saved as an indexed CA Process Automation type. The type of the first object in the array of objects defines the CA Process Automation type.
• Undefined is saved as a CA Process Automation string with 'undefined’ as its value.
• Any other Java object not listed here is serialized and saved as a CA Process Automation JavaObject.

  Note: The Java object must be serializable (implements java.io.Serializable) to save it as a CA Process Automation JavaObject. Otherwise, the operator fails with the reason:

  Error when serializing object of class: x. Object is not serializable.
  

  Where x is the class name of the object.
