getRequestMetadata(URI uri, Executor executor, RequestMetadataCallback callback)

public void getRequestMetadata(URI uri, Executor executor, RequestMetadataCallback callback)

Get the current request metadata without blocking.

This should be called by the transport layer on each request, and the data should be populated in headers or other context. The implementation can either call the callback inline or asynchronously. Either way it should never block in this method. The executor is provided for tasks that may block.

The default implementation will just call #getRequestMetadata(URI) then the callback from the given executor.

The convention for handling binary data is for the key in the returned map to end with "-bin" and for the corresponding values to be base64 encoded.
