Parameters in Mapplets

You can bind a mapplet parameter to a parameter in a data object or in a transformation that is in the mapplet.

When you define a mapplet parameter, you can bind the mapplet parameter to a specific transformation parameter. The mapplet parameter value overrides the default parameter value in the transformation. When you bind a mapplet parameter to a transformation parameter, the parameters must be the same type. The mapplet parameter name does not have to be the same as the transformation parameter name. You can bind a mapplet parameter to more than one transformation parameter.

Use one of the following methods to define mapplet parameters:

Define mapplet parameters on the Parameters tab of the mapplet Properties view: On the mapplet
Parameters
tab, you can manually enter each parameter name, parameter attributes, and default value. After you define a parameter, you can view and access the parameter in the Outline view.
Add mapplet parameters from transformation parameters: After you add a transformation to a mapplet, you can create the mapplet parameter directly from the transformation
Parameters
tab.
