public abstract class NumberExpressionBase extends java.lang.Object implements NumberExpression
NumberExpressionBase
contains convenience methods to generate bindings in a fluent style,
that are common to all NumberExpression subclasses.
NumberExpressionBase serves as a place for common code of specific NumberExpression subclasses for the specific number type.
