com.bigdata.bop.BOpBase

com.bigdata.bop.PipelineOp

com.bigdata.bop.paths.ZeroLengthPathOp

All Implemented Interfaces:

BOp, IPropertySet, Serializable, Cloneable

Deprecated.

Does not work. Leads to cardinality problems and can be removed. Zero Length Paths are integrated into the ALP node / ArbitraryLengthPathOp now.

public class ZeroLengthPathOp
extends PipelineOp

An attempt to solve the zero length path problem with its own operator.

Deprecated.

Deep copy constructor.

Parameters:

op -

public ZeroLengthPathOp(BOp[] args,
                Map<String,Object> annotations)

Deprecated.

Shallow copy constructor.

Parameters:

args -

Method Detail

eval

public FutureTask<Void> eval(BOpContext<IBindingSet> context)

Deprecated.

Description copied from class: PipelineOp

Return a FutureTask which computes the operator against the evaluation context. The caller is responsible for executing the FutureTask (this gives them the ability to hook the completion of the computation).

Specified by:

eval in class PipelineOp

Parameters:

context - The evaluation context.

Returns:

The FutureTask which will compute the operator's evaluation.
