value of expression

evaluate

public KnowledgeRecord evaluate(KnowledgeBase.CompiledExpression expression,
                                EvalSettings evalSettings)

Evaluates an expression. The returned KnowledgeRecord should either be freed (() KnowledgeRecord.free ()) or returned

Parameters:

expression - KaRL expression to evaluate (result of (String))

evalSettings - Settings for evaluating and printing

Returns:

value of expression

compile
