Constructor Detail

XSDBooleanIVValueExpression

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

Required shallow copy constructor.

XSDBooleanIVValueExpression

public XSDBooleanIVValueExpression(XSDBooleanIVValueExpression op)

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

Method Detail

wrap

protected static final XSDBooleanIVValueExpression wrap(IValueExpression<? extends IV> ve)

If the operand is not known to evaluate to a boolean, wrap it with an EBVBOp.

Returns:

An operand which is known to evaluate to an XSDBooleanIV.

areGlobalsRequired

protected boolean areGlobalsRequired()

None of the xsd:boolean IV value expressions require access to the ValueFactory or LexiconConfiguration.

Overrides:

areGlobalsRequired in class IVValueExpression<XSDBooleanIV>

get

public final XSDBooleanIV get(IBindingSet bs)

Delegates to accept(IBindingSet).

Parameters:

bs - The binding set.

Returns:

The as bound value of the constant, variable, or expression.

accept

protected abstract boolean accept(IBindingSet bs)

Implement this method.

Parameters:

bs - The source solution.

Returns:

true iff the function accepts the solution.
