Graph Parameter Editor

Detailed List of Available Operations
Properties of Graph Parameters
Graph Parameter Type Editor

Graph parameters are managed by Graph parameters editor. Main purpose of this editor is to create, edit and remove internal graph parameters, link and unlink external parameter files and edit particular graph parameters inside parameter files.

Graph parameter editor is available via Outline view. Just double-click on Graph parameters section.

Example of a Graph parameters editor

Figure 37.3. Example of a Graph parameters editor

Both internal and external graph parameters are managed by this editor at once. Internal parameters are on top-level of tree and external parameter files are represented by sub-trees (for example workspace.prm in the figure above).

Order of graph parameters defines usage priority. In case of parameters name collision, the parameter above the other has higher priority. The order of graph parameters can be changed using drag and drop or move actions available on left-side toolbar.

In case of some error being detected in graph parameters setting, yellow exclamation mark icon is shown over affected graph parameters and an error message is displayed in tooltip on corrupted graph parameter.

Detailed List of Available Operations

  • Adding a new graph parameter use

    To add a new parameter to the end of the list use in-line editing of Add new parameter cell at the end of each parameter section. To insert a new graph parameter above current position use Plus button on the left side.

  • Removing a graph parameter

    Use Minus button or Delete key to remove selected parameters. Multi-selection is supported. If you would like to remove unused graph parameters, use Cleanup Unused Elements.

  • Name and value editing

    Edit name and value of graph parameter directly in parameters viewer.

  • Changing the order of parameters

    Use left-side toolbar (Move top, Move up, Move down, Move bottom) or Drag&Drop to move selected graph parameter. Order of parameter files can be changed as well. Multi-selection is supported.

  • Creating a new parameter file

    Create new parameter file using button New parameter file.

  • Linking an existing parameter file

    Link existing parameter file using button Link parameter file

  • Filtering parameters

    Parameters filtering is based on substring of parameter name and value.

Dialog supports commonly used operations known from graph editor:

  • Copy (Ctrl+C), Cut (Ctrl+X) and Paste (Ctrl+V) operation on selected graph parameters.

  • Undo (Ctrl+Z) and Redo (Ctrl+Y) operations.

Properties of Graph Parameters

  • Name

    Identifier of the parameter.

  • Value

    Value of the parameter. The Value field can use different editors to edit the value. The editors are set up using property Editor type.

  • Secure

    The parameter is considered as a Secure parameter. See Secure Graph Parameters

  • Description

    Description is user defined text for a graph parameter or for a graph parameter file. Contrary to the label the description can be several paragraphs long.

  • Public

    Public parameters serve for configuration of subgraphs. See Configuring Subgraphs.

  • Required

    This field is available in public parameters only. If a parameter of a subgraph is marked as required and the subgraph as is used as a component, the corresponding attribute of the subgraph component is mandatory and user has to set it up.

  • Label

    Label is a short description of the field appearing as an attribute name in a subgraph component. This field is available in public parameters only.

  • Value Hint

    This value is displayed in the value column in the properties of subgraphs component. The value helps user of subgraph to decide which value should be filled in to the user-defined graph attribute. The field is available in public parameters only.

  • Category

    Category of component attributes in which is parameter displayed: Basic or Advanced. Basic is default category. This field is available in public parameters.

  • Editor Type

    The public parameters can use type of editor corresponding to the field of the component using the parameter. You can use for example File URL Editor or Transform Editor. This field is available for all parameters.

    The editor type is primarily used for public parameters when setting them in parent graph (when configuring a subgraph).

Component Binding

Component binding serves to bind the parameter to an attribute of existing component of subgraph. You can for example set up parameter Transform in Reformat component using public graph parameters.

Content of lists of components available in Component binding depends on components available in subgraph.

Edit Parameter Value

Edit Parameter Value serves to set up parameter value. The value of the parameter can be converted to the CTL2 code using Convert to dynamic button.

Edit Parameter Value

Figure 37.6. Edit Parameter Value

If the Convert to dynamic button is used, the editor is changed.

Edit Parameter CTL2 Value

The Edit Parameter CTL2 Value dialog serves to place a CTL2 code as a parameter value.

Edit Parameter Value

Multiline String Editor

Multiline string parameter type lets you use a multiline string as a parameter value. If the parameter value is in xml or json format, its syntax can be checked.

Use Validation configuration property to switch on xml or json syntax validation.
