Comparable<Binding>
public class Binding extends Object implements Comparable<Binding>
An immutable binding of a set of dimensions to values. This binding is minimal in that it only includes dimensions which actually have values.- Author:

Method Summary
All Methods Static Methods Instance Methods Concrete Methods Modifier and Type Method Description int
compareTo(Binding other)
Implements a partial ordering where more specific bindings come before less specific ones, taking both the number of bindings and their positions into account (earlier dimensions take precedence over later ones).static Binding
createFrom(DimensionBinding dimensionBinding)
boolean
equals(Object o)
Returns whether the given binding has exactly the same values as thisboolean
generalizes(Binding other)
Returns whether this binding is a proper generalization of the given binding: Meaning it contains a proper subset of the given bindings.int

boolean
isNull()
Returns true only if this binding is null (contains no values for its dimensions (if any)boolean
matches(Map<String,String> context)
Returns true if all the dimension values in this have the same values in the given context.String

compareTo
public int compareTo(Binding other)
Implements a partial ordering where more specific bindings come before less specific ones, taking both the number of bindings and their positions into account (earlier dimensions take precedence over later ones).The order is not well defined for bindings in different dimensional spaces.
