abstract class Pickler[T] extends AnyRef
An abstract class for writing and reading Scala objects to and from a legible representation. The representation 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.
- T
the type of values handled by this pickler. These Picklers build on the work of Andrew Kennedy. They are most closely inspired by Iulian Dragos' picklers for Scala to XML. See: https://code.google.com/p/gdata-scala-client/wiki/DevelopersGuide

Abstract Value Members
- abstract def pickle(wr: Writer, x: T): Unit
Writes value in pickled form
Writes value in pickled form
- wr
the writer to which pickled form is written
- x
the value to write
- abstract 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
UnpickleSuccessvalue if the current input corresponds to the kind of value that is unpickled by the current subclass ofPickler, anUnpickleFailurevalue otherwise.
- Exceptions thrown
Lexer.MalformedInputif input is invalid, or if anUnpickle
