Description copied from interface: ClientInterceptor

Intercept Call creation by the next Channel.

Many variations of interception are possible. Complex implementations may return a wrapper around the result of next.newCall(), whereas a simpler implementation may just modify the header metadata prior to returning the result of next.newCall().

Specified by:

interceptCall in interface ClientInterceptor

Parameters:

method - the remote method to be called.

next - the channel which is being intercepted.

Returns:

the call object for the remote operation, never null.
