Caster

A caster takes the untyped value returned by the PB reflection APIs and provides a typesafe value. It is also responsible for determining whether a path adhere's to the desired stated type in the ProtoAccessor factory methods.

A: type of GeneratedMessage from which data should be extracted.
B: type of data to be extracted from A.

Abstract Value Members

abstract def cast(hasField: Boolean, value: Any): B

Cast the untyped value returned by the PB reflection API and give it a proper type.
Cast the untyped value returned by the PB reflection API and give it a proper type.
hasField
whether the field was present in the PB instance (true) or it is a default value (false).
value
the value to cast.
returns
a typed version of value.
abstract def error(path: String, fds: ::[FieldDescriptor])(implicit ops: ProtoOps[A]): Option[String]

Determine if there is an error in creating a ProtoAccessor.
Determine if there is an error in creating a ProtoAccessor. If there is an error, an error message will be returned.
path
raw string-based path representation
fds
FieldDescriptor-based path representation
ops
possible used for type checking.
returns
an error message in a Some if there was an error; otherwise, None.
