Constructor Detail

ExactlyOneExpression

public ExactlyOneExpression(TermCompositorType expression)

Parameters:

expression - a term compositor representing an ExactlyOne expression

Method Detail

interpret

protected TermType[] interpret(TermType[] terms,
                               InterpreterContext context)
                        throws InterpreterException

template method that implements a specific interpretation strategy. The strategy interprets a set of terms and returns a result, i.e. the selected term in an ExactlyOne statement.

Specified by:

interpret in class AbstractExpression

Parameters:

terms - the terms to interpret

context - the interpreter context

Returns:

the strategy result, i.e. a filtered term list

Throws:

InterpreterException - indicates an error during the term interpretation
