Method Detail

get

E get(IBindingSet bindingSet)

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.

Parameters:

bindingSet - The binding set.

Returns:

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

Throws:

IllegalArgumentException - if this is an IVariable and the bindingSet is null.
