• put

  public abstract void put(String name,
         Object val)

  Put the value of the named Object field into the persistent field.

  Parameters:

  name - the name of the serializable field

  val - the value to assign to the field (which may be null)

  Throws:

  IllegalArgumentException - if name does not match the name of a serializable field for the class whose fields are being written, or if the type of the named field is not a reference type

• write

  @Deprecated
  public abstract void write(ObjectOutput out)
                      throws IOException

  Deprecated. This method does not write the values contained by this PutField object in a proper format, and may result in corruption of the serialization stream. The correct way to write PutField data is by calling the ObjectOutputStream.writeFields() method.
  Write the data and fields to the specified ObjectOutput stream, which must be the same stream that produced this PutField object.

  Parameters:

  out - the stream to write the data and fields to

  Throws:

  IOException - if I/O errors occur while writing to the underlying stream

  IllegalArgumentException - if the specified stream is not the same stream that produced this PutField object
