Constructor Detail

EvlValidator

public EvlValidator()

Note when using this constructor, make sure to call initialise(URI, String, String, String) afterwards

EvlValidator

public EvlValidator(URI source,
            String modelName,
            String ePackageUri,
            String bundleId)

Method Detail

initialise

public void initialise(URI source,
              String modelName,
              String ePackageUri,
              String bundleId)

addDiagnosticianVariable

public void addDiagnosticianVariable(String name)

Indicates that the value of the entry of the Diagnostician context Map with the specified name should be published as a global variable in the EVL script. If the context map does not contain an entry with the specified name, the variable will be set to null.

Note: this map is received through the validate methods in this class.

Parameters:

packageUri - Namespace URI of the package
