Type
| Type | Scope | Definition |
|---|---|---|
| Internal | Graph | Defined in the graph in the Parameters section of the Outline panel |
| Parameter File | Global | A file that contains the parameters |
Special
- Today, value:
return date2str(today(), "YYYY-MM-dd");
Hierarchy
Hierarchy of graph parameter definitions:
- Parameter from external parameter file specified at the start of graph execution by -cfg option
- Parameter defined at the start of graph execution by -P option
- Parameter from external parameter file that is linked to the graph during the graph development
- Internal graph parameter
- Environment variable
How to
- Use a parameter in a transformation
$in.myParameter
- in CTL, get their value via
getParamValue("MyParameter")
- Pass a parameter in a runGraph component. JVM must be set to false.
test1.grf|"-P:my_param=my_value" "-P:another_param=value1"
test2.grf|"-P:my_param=my_value2" "-P:another_param=value2"
- Set a parameter programmatically from a Reformat component with in-line Java code.
// Get a value from a data flow
String parameterValue = ((CloverString) getInputRecord(0).getField("myParameterNameColumn").getValue()).toString();
// or
String parameterValue = GetVal.getString(source[0],"myParameterNameColumn");
/** Set the parameter to which it is stored, "myParameterName" in this case.*/
getGraph().getGraphProperties().setProperty("myParameterName", parameterValue );
Workspace.prm
The parameters are stored in the file Workspace.prm

You can define it by graph.
