Method Detail

getInstance

public static EvaluationConfigurator getInstance()

Retrieves configurator singleton

Returns:

configurator singleton

getAvailableLanguages

public java.util.Set<java.lang.String> getAvailableLanguages()

Enumerates available evaluatable languages for opaque expressions Currently (as of v12.5) 2 languages are supported - "Binary" and "OCL2.0"

Returns:

set of the available languages (strings)

getEvaluatorForLanguage

public Evaluator getEvaluatorForLanguage(java.lang.String lang)

Retrieves the appropriate evaluator, which knows how to evaluate expressions of the given language

Parameters:

lang - one of the evaluatable languages

Returns:

evaluator object, suitable for expression evaluation or null if language is not evaluatable

registerBinaryImplementers

public void registerBinaryImplementers(java.lang.ClassLoader cl)

Method allows registering additional class loaders, to load classes, implementing binary expressions. This is especially necessary for expression implementations, coming from plugins (otherwise these implementation classes will not be found - since they are in a separate class loader - plugin class loader).

Parameters:

cl - class loader, supplying additional classes, implementing expressions

registerEvaluator

public void registerEvaluator(java.lang.String language,
                              Evaluator evaluator)

Registers evaluator for the specified language.

Parameters:

language - language identifier.

evaluator - an evaluator object.

unregisterEvaluator

public void unregisterEvaluator(java.lang.String language)

Unregisters evaluator for the specified language.

Parameters:

language - language identifier.
