    canPickle

    The predicate that indicates whether a given value can be pickled by instances of this class.

Abstract Value Members

  1. 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

    Pickler
  2. 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 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.

Concrete Value Members

  1. def asClass[U <: T](c: Class[U]): CondPickler[T]

    A conditional pickler handling values of some Scala class.

    A conditional pickler handling values of some Scala class. It adds the class name as a label to the representation of the current pickler and

    c

    the class of values handled by this pickler.

  3. def cond(p: (Any) => Boolean): CondPickler[T]

    A conditional pickler obtained from the current pickler.

    A conditional pickler obtained from the current pickler.

    p

    the condition to test to find out whether pickler can handle some Scala value.

  4. def labelled(label: String): Pickler[T]

    A pickler that adds a label to the current pickler, using the representation label ( <current pickler> )

    A pickler that adds a label to the current pickler, using the representation label ( <current pickler> )

    label

    the string to be added as a label.

    Pickler
  5. def tryPickle(wr: Writer, x: Any): Boolean

    Pickles given value x if possible, as indicated by canPickle(x).

  6. def wrapped[U](in: (T) => U)(out: (U) => T): Pickler[U]

    A pickler obtained from the current pickler by a pair of transformer functions

    A pickler obtained from the current pickler by a pair of transformer functions

    in

    the function that maps values handled by the current pickler to values handled by the wrapped pickler.

    out

    the function that maps values handled by the wrapped pickler to values handled by the current pickler.

    Pickler
  7. def |[V >: T, U <: V](that: => CondPickler[U]): CondPickler[V]

    A pickler obtained from this pickler and an alternative pickler.

    A pickler obtained from this pickler and an alternative pickler. To pickle a value, this pickler is tried first. If it cannot handle the object (as indicated by its canPickle test), then the alternative pickler is tried. To unpickle a value, this unpickler is tried first. If it cannot read the input (as indicated by a UnpickleFailure result), then the alternative pickler is tried.

    V

    The handled type of the returned pickler.

    U

    The handled type of the alternative pickler.

    that

    The alternative pickler.

  8. def ~[U](that: => Pickler[U]): Pickler[~[T, U]]

    A pickler representing a ~-pair of values as two consecutive pickled strings, separated by a comma.

    A pickler representing a ~-pair of values as two consecutive pickled strings, separated by a comma.

    that

    the second pickler which together with the current pickler makes up the pair this ~ that to be pickled.
