Interface PortableReader

All Known Implementing Classes:

DefaultPortableReader, MorphingPortableReader

public interface PortableReader

Provides a mean of reading portable fields from a binary in form of java primitives arrays of java primitives , nested portable fields and array of portable fields.

PortableReader read method family support nested paths. For example body.brain.iq is a valid nested path.
