Method Detail

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.

getRequirement

public INeedsMaterialization.Requirement getRequirement()

This bop can only work with materialized terms.

Specified by:

getRequirement in interface INeedsMaterialization
