trait ObjectOutput extends SequentialOutput

Represents an abstract sink for serialization of string-to-value mappings. Any ObjectOutput instance must be assumed to be stateful and used in strictly sequential manner. After all key-value pairs have been written, finish() must be called to explicitly mark that the object is complete.

ObjectOutput MUST preserve information about the order in which fields are written. ObjectInput is required to read fields in exactly the same order as ObjectOutput writes them.

Abstract Value Members

  1. abstract def finish(): Unit

    Indicates that all elements or fields in this SequentialOutput have been written.

    Indicates that all elements or fields in this SequentialOutput have been written. This method MUST always be called after list/object writing has been finished.

  3. abstract def writeField(key: String): Output

    Returns an Output representing value mapped to given string key.

    Returns an Output representing value mapped to given string key. This Output instance must be fully used before calling writeField next time. That means, one can NOT simultaneously use multiple instances of Output returned by subsequent calls to this method.
