Description copied from interface: EvaluationStrategy

Evaluates the tuple expression against the supplied triple source with the specified set of variable bindings as input.

Specified by:

evaluate in interface EvaluationStrategy

Overrides:

evaluate in class StrictEvaluationStrategy

Parameters:

expr - The Tuple Expression to evaluate

bindings - The variables bindings to use for evaluating the expression, if applicable.

Returns:

A closeable iterator over the variable binding sets that match the tuple expression.

Throws:

QueryEvaluationException
