All Implemented Interfaces:

BOp, IValueExpression<XSDBooleanIV>, IPropertySet, Serializable, Cloneable

public class AndBOp
extends XSDBooleanIVValueExpression

Imposes the constraint x AND y. Each operand of this operator must evaluate to a boolean. If the operand is not known to evaluate to a boolean, it is wrapped with an EBVBOp.

Method Detail

get

public XSDBooleanIVValueExpression get(int i)

Description copied from interface: BOp

Return an argument to the operation.

Specified by:

get in interface BOp

Overrides:

get in class IVValueExpression<XSDBooleanIV>

Parameters:

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

Returns:

The argument.

accept

public boolean accept(IBindingSet bs)

Follows semantics from SPARQL spec - "Testing Values".

see http://www.w3.org/TR/rdf-sparql-query/#tests section 11.2

Specified by:

accept in class XSDBooleanIVValueExpression

Parameters:

bs - The source solution.

Returns:

true iff the function accepts the solution.
