All Implemented Interfaces:
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.

    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 this
    boolean
    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
    hashCode()
     
    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
    toString()

    • matches

      public boolean matches(Map<String,String> context)
      Returns true if all the dimension values in this have the same values in the given context.

    • 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.
