Method Detail

get

public Boolean get(IBindingSet s)

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 BooleanValueExpression

Specified by:

get in interface IValueExpression<Boolean>

Parameters:

s - The binding set.

Returns:

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