Interface BinaryReader

public interface BinaryReader

Reader for binary objects used in Binarylizable implementations. Useful for the cases when user wants a fine-grained control over serialization.

Note that Ignite never writes full strings for field or type names. Instead, for performance reasons, Ignite writes integer hash codes for type and field names. It has been tested that hash code conflicts for the type names or the field names within the same type are virtually non-existent and, to gain performance, it is safe to work with hash codes. For the cases when hash codes for different types or fields actually do collide, Ignite provides BinaryIdMapper which allows to override the automatically generated hash code IDs for the type and field names.
