  • Method Details

    • getName

      String getName()
      Gets the name of the binding (e.g. the variable name).
      Returns:
      The name of the binding.

    • getValue

      Returns:
      The value of the binding, never null.

    • equals

      boolean equals(Object o)
      Compares a binding object to another object.
      Overrides:
      equals in class Object
      Parameters:
      o - The object to compare this binding to.
      Returns:
      true if the other object is an instance of Binding and both their names and values are equal, false otherwise.

    • hashCode

      int hashCode()
      The hash code of a binding is defined as the bit-wise XOR of the hash codes of its name and value: 
       name.hashCode() ˆ value.hashCode()
      .
      Overrides:
      hashCode in class Object
      Returns:
      A hash code for the binding.
