Method Detail

getRequirement

public INeedsMaterialization.Requirement getRequirement()

This is a Requirement#SOMETIMES because it can operate on inline IVs without materialization but requires materialization of non-inline IVs.

Specified by:

getRequirement in interface INeedsMaterialization

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.
