Writing an Array Parameter to a File

You can map the elements of an array parameter to selected rows in the text file.

Before you begin: You must specify the file to write and display its content in the Parse tab of the Text Parser Editor before you map a parameter to a selected section of the file.

  1. Display the content of the file to parse, as described in Specifying the File to Parse.
  2. From the display area on the left side of the Text Parser Editor, select the text to associate with the parameter.

    Tips: You can create a marker indicating the relative position of the mapping in the text file, as described in Defining a Marker. You can also click , , and to help you locate the text to select.

    A context toolbar with several options appears.
  3. To map the parameter's value to the selected text, do one of the following:
    ActionInstructions
    Map to a new parameter immediately From the context toolbar, select .
    Map to an existing parameter immediatelyFrom the parameter list, select an array parameter. From the list of icons at the center of the dialog box, select .
    Map to a new or existing parameter and configure the parse

    1. From the context toolbar or the list of icons in the center of the dialog box, select .

    2. In the dialog box that appears, type the parameter name, which can be new or existing.

    3. Select 1D Array or 2D Array from the Map with list, and configure the options described in Configuring a Write Operation.

    Note: You can map a parameter to multiple locations in the file. The parser writes the same parameter value to each of the specified locations.

    If you choose to map immediately, Optimization Process Composer maps values to as many consecutive rows as possible, as long as each row contains at least as many values as you originally selected, regardless of their type. It creates an array parameter of the appropriate type and dimension if it does not already exist.
  4. Optional: If desired, select to insert the contents of a selected file in front of the line containing the selected text. You can use this option to improve the performance of the Text Parser adapter by restricting the parsing operation to only portions of the file that are changing.

    You can enter the name of the file to insert or select the name of a file from a local directory. The file must be present in the working directory when the Text Parser adapter runs.

    The text in the Actions area describes the file that will be inserted and the line number of the insertion point.
  5. Optional: If desired, you can delete parameters or mappings using any of the following methods:
    1. Select a parameter and click from above the parameter list to remove the parameter along with its mapping.
    2. Click anywhere within the highlighted text related to the mapping. From the context toolbar that appears, click to remove only the mapping.
    3. Select a parameter and click from the icon list in the center of the dialog box to remove only the mapping.
  6. Click Ok to save your changes and to close the Text Parser Editor.
