Method Details

section

public boolean section(String name,
 Checkpoint.StateReader reader)
                throws IOException

Restores one model from the named section. Returns false when the section is absent (model keeps its current state — the caller decides whether that is a cold start or an error). Throws when the model does not consume the payload exactly: leftover bytes mean the writer and reader disagree about the format.

Throws:

IOException
