Parameter is an well-established functionality in SystemWeaver that enables Architects to parameterize configurable views (i.e., graph, grid, chart and report) so that a certain view can work for different items. In addition to being able to use Parameters with items, it is also possible to use it with string, integer and boolean data types. This article provides examples of how to use Parameters with these types.


Prerequisites


You must use the optional "as" attribute in the Parameter definition to indicate "String", "Boolean", or "Integer". If as is not defined, it will default to "Item".


Only parameters of type Item are added to contexts. Other parameter values are only available through variables.


Example Parameter Configurations

For Type String

<Parameters>
    <Parameter caption="Section" name="p1" as="String" >
      <Values>
        <ForEach select="['One', 'Two', 'Three']">
          <AddValue/>
        </ForEach>
      </Values>
    </Parameter>
  </Parameters> 

For Type Boolean

 <Parameters>
    <Parameter caption="Section" name="p1" as="Boolean" >
      <Values>
        <ForEach select="[true, false]">
          <AddValue/>
        </ForEach>
      </Values>
    </Parameter>
  </Parameters>

For Type Integer

 <Parameters>
    <Parameter caption="Section" name="p1" as="Integer" >
      <Values>
        <ForEach select="[1, 2, 3]">
          <AddValue/>
        </ForEach>
      </Values>
    </Parameter>
  </Parameters>


Example Use Case for String Data Type

Below is a use case for a String data type for parameter. The use case is to provide end users with different views of Unallocated design (functions design), where the user can choose to see:

  • Detailed function design (with function boundary), or
  • Overall components design (without function boundary), or 
  • Simplified functions design (only connection between functions)

It is possible to use more than one parameter of different types, but for the simplicity of this example we are just using one parameter of type String.
