getOrderedCodersback to summary
pack-priv Iterable<Coder> getOrderedCoders() throws IOException

Sorts Coders using bind pairs.

The first coder reads from the packed stream (we currently only support single input stream decoders), the second reads from the output of the first and so on.

public String toString()

Overrides java.lang.Object.toString.

Doc from java.lang.Object.toString.

Returns a string representation of the object.

Returns:String

a string representation of the object.
