ice_invokeAsync() [1/4]

std::future< std::tuple< bool, std::vector< std::byte > > > Ice::ObjectPrx::ice_invokeAsync ( std::string_view operation, Ice::OperationMode mode, const std::vector< std::byte > & inParams, const Ice::Context & context = Ice::noExplicitContext ) const

nodiscard

Invokes an operation asynchronously.

Parameters

operation	The name of the operation to invoke.
mode	The operation mode (normal or idempotent).
inParams	An encapsulation containing the encoded in-parameters for the operation. You can pass an empty byte sequence when the operation takes no in-parameters; the Ice runtime then marshals an empty encapsulation.
context	The request context.

Returns

A future that becomes available when the invocation completes. This future holds:

• returnValue true if the operation completed successfully, false if it completed with a user exception.
• outParams An encapsulation containing the encoded result.

Remarks

When this proxy is a oneway, datagram, or batch proxy, the future completes with returnValue true and an empty outParams as soon as the request is accepted by the transport or added to the batch.
