  • Method Details

    • getInstance

      public static Pair.Externalizer getInstance()
      Get the single instance. Though multiple instances can be created using the public constructor, only a single instance need be used in practice since this class maintains no internal state.
      Returns:
      the instance

    • writeExternal

      public void writeExternal(Object subject, ObjectOutput output) throws IOException
      Write the external representation of an object. The object's class and the externalizer's class will already have been written.
      Specified by:
      writeExternal in interface Externalizer
      Parameters:
      subject - the object to externalize
      output - the output
      Throws:
      IOException - if an error occurs

    • createExternal

      public Object createExternal(Class<?> subjectType, ObjectInput input) throws IOException, ClassNotFoundException
      Create an instance of a type. The object may then be initialized from input, or that may be deferred to the readExternal() method. Instances may simply delegate the task to the given Creator. Note that this method is called only on the leaf class, so externalizers for non-final classes that initialize the instance from the stream need to be aware of this.
      Specified by:
      createExternal in interface Externalizer
      Parameters:
      subjectType - the type of object to create
      input - the input
      Returns:
      the new instance
      Throws:
      IOException - if an error occurs
      ClassNotFoundException - if a class could not be found during read

    • writeExternal

      public void writeExternal(ObjectOutput out)
      Specified by:
      writeExternal in interface Externalizable

    • readExternal

      public void readExternal(ObjectInput in)
      Specified by:
      readExternal in interface Externalizable

    • readResolve

      protected Object readResolve()
      Resolve the object to the single externalizer instance.
      Returns:
      the instance
