Using Global Variables

The available global variables for each type of script are described in the following sections:

• The global variables for the Script component and for component prologues and epilogues are described in Global Variables for Script, Prologue, and Epilogue.

• The global variables for model and component customization scripts are described in Customizing Models in the Isight User’s Guide.

The global variables behave identically in both the Jython and DynamicJava languages in that you call methods on these objects in the standard way. Methods may return objects that can be further processed.

For example, a component customization script has access to the DtComponent object for the component being customized, as a global variable component. In Jython, you could get a property of the component and change its value as follows:

prop = component.getProperty('script')
prop.getValueObj().setValue('# a new, empty script')

In this script, component is the name of the global variable that holds the DtComponent object.

In the script editor interface, global variables are always shown as underlined to make it clear that they are not standard script variables or parameters.

Do not assign a new value to a global variable. For example:

localDir = new File("foo/bar");   // Don't do this!
