Pickler

class Pickler [T] extends AnyRef

An abstract class for writing and reading Scala objects to and from a legible representation. The presesentation follows the following grammar:

 Pickled = `true' | `false' | `null' | NumericLit | StringLit |
           Labelled | Pickled `,' Pickled
 Labelled = StringLit `(' Pickled? `)'

All ...Lit classes are as in JSON. @see scala.tools.nsc.io.Lexer

Subclasses of Pickler each can write and read individual classes of values.

Abstract Value Members

  1. def pickle (wr: Writer, x: T): Unit

    Writes value in pickled form

    Writes value in pickled form

    wr

  2. def unpickle (rd: Lexer): Unpickled[T]

    Reads value from pickled form.

    Reads value from pickled form.

    rd

    the lexer from which lexemes are read

    returns

    An UnpickleSuccess value if the current input corresponds to the kind of value that is unpickled by the current subclass of Pickler, an UnpickleFailure value otherwise.
