Constructor Detail

SPARQLConstraint

public SPARQLConstraint(IValueExpression<? extends IV> x)

Construct a SPARQL constraint using the specified value expression. The value expression will be automatically wrapped inside an EBVBOp if it does not itself evaluate to a boolean.

SPARQLConstraint

public SPARQLConstraint(BOp[] args,
                Map<String,Object> anns)

Required shallow copy constructor.

SPARQLConstraint

public SPARQLConstraint(SPARQLConstraint<X> op)

Constructor required for com.bigdata.bop.BOpUtility#deepCopy(FilterNode).

Method Detail

get

public IValueExpression<? extends XSDBooleanIV> get(int i)

Description copied from interface: BOp

Return an argument to the operation.

Specified by:

get in interface BOp

Overrides:

get in class BOpBase

Parameters:

i - The argument index in [0:BOp.arity()-1].

Returns:

The argument.

accept

public boolean accept(IBindingSet bs)

Description copied from interface: IConstraint

Return true if the binding set satisfies the constraint.

Specified by:

accept in interface IConstraint

Overrides:

accept in class Constraint<X extends XSDBooleanIV>

Parameters:

bs - The binding set.

toShortString

public String toShortString()

Overridden to provide a little bit of information about the attached constraint.

Specified by:

toShortString in interface BOp

Overrides:

toShortString in class CoreBaseBOp
