Class NARKey

java.lang.Object
com.nt.udc.nar.NARKey
All Implemented Interfaces:
Serializable
public class NARKey extends Object implements Serializable
This class implements a simple NAR key. For the most part, this class should be used when the user needs to deal with a set of NAR's, but would like to access them via a key, rather than by searching (such as in a Hashtable-type Object).

      Parameters:
      value - Bytes, to be used as the hash code

    • NARKey

      public NARKey(NAR nar, int[] attrs) throws NullPointerException
      Creates a NAR Key from the given NAR, using the given attributes to build the key.
      Parameters:
      nar - NAR to build the key from.
      attrs - Attributes to use when building the key.
      Throws:
      NullPointerException

      public byte[] toBytes()
      Returns the byte array value for this key.

    • hashCode

      public int hashCode()
      Returns the hash code of this NARKey.
      Overrides:
      hashCode in class Object
      Returns:
      Hash code of this NARKey.

    • equals

      public boolean equals(Object o)

      equals in class Object
      Parameters:
      o - NARKey Object to compare.
      Returns:
      true, if keys are equal

    • toString

      public String toString()
      Converts this key to a String.
      Overrides:
      toString in class Object
      Returns:
      Key, in String format.
