Description copied from class: StreamInput

Reads a NamedWriteable from the current stream, by first reading its name and then looking for the corresponding entry in the registry by name, so that the proper object can be read and returned. Default implementation throws UnsupportedOperationException as StreamInput doesn't hold a registry. Use FilterInputStream instead which wraps a stream and supports a NamedWriteableRegistry too.

Overrides:

readNamedWriteable in class StreamInput

Throws:

java.io.IOException
