GrpcCall

The method invoked by this call.

A map containing request metadata. This is initially empty; it can be assigned to any other map of metadata before the call is executed. It is an error to set this value after the call is executed.

A map containing response metadata. This is null until the call has executed, at which point it will be non-null if the call completed successfully. It may also be non-null in failure cases if the failure was not a problem of connectivity. For example, if the gRPC call fails with an HTTP 503 error, response metadata will be present.

Configures how long the call can take to complete before it is automatically canceled.

Attempts to cancel the call. This function is safe to call concurrently with execution. When canceled, execution fails with an immediate IOException rather than waiting to complete normally.

Create a new, identical gRPC call to this one which can be enqueued or executed even if this call has already been.

Enqueues this call for asynchronous execution. The callback will be invoked on the client's dispatcher thread when the call completes.

Invokes the call immediately and suspends until its response is received.

Invokes the call immediately and blocks until its response is received.

True if cancel was called.

Returns true if execute, executeBlocking, or enqueue was called. It is an error to execute or enqueue a call more than once.
