Description copied from interface: ClientInterceptor

Intercept ClientCall 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().

next.newCall() must not be called under a different Context other than the current Context. The outcome of such usage is undefined and may cause memory leak due to unbounded chain of Contexts.

Specified by:

interceptCall in interface ClientInterceptor

Parameters:

method - the remote method to be called.

callOptions - the runtime options to be applied to this call.

next - the channel which is being intercepted.

Returns:

the call object for the remote operation, never null.
