IfBOp

public IfBOp(IValueExpression<? extends IV> conditional,
     IValueExpression<? extends IV> expression1,
     IValueExpression<? extends IV> expression2)

IfBOp

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

Required shallow copy constructor.

IfBOp

public IfBOp(IfBOp op)

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

Method Detail

areGlobalsRequired

protected boolean areGlobalsRequired()

Description copied from class: IVValueExpression

Returns true unless overridden, meaning the GlobalAnnotations are required for this value expression (certain boolean value expressions do not require them). Global annotations allow the method getValueFactory and getLexiconConfiguration to work.

Overrides:

areGlobalsRequired in class IVValueExpression<IV>

get

public IV get(IBindingSet bs)

Description copied from interface: IValueExpression

Return the as bound value of the variable, constant, or expression. The as bound value of an IConstant is the contant's value. The as bound value of an IVariable is the bound value in the given IBindingSet -or- null if the variable is not bound in the IBindingSet.

Specified by:

get in interface IValueExpression<IV>

Parameters:

bs - The binding set.

Returns:

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