		std::function< void(bool)>	response,

Tests whether this object supports a specific Slice interface.

Parameters

typeId	The type ID of the Slice interface to test against.
response	The response callback. The Ice runtime calls this function from an Ice thread pool thread. If you set InitializationData::executor, the executor determines the thread that executes this function. It accepts: true if the target object implements the Slice interface specified by typeId or implements a derived interface, false otherwise.
ex	The exception callback. The Ice runtime calls this function from an Ice thread pool thread. If you set InitializationData::executor, the executor determines the thread that executes this function.
sent	The sent callback. The Ice runtime calls this function when the request is accepted by the transport. When the request is accepted synchronously, the Ice runtime calls this function from the current thread and passes true as argument. When the request is accepted asynchronously, the Ice runtime calls this function from an Ice thread pool thread and passes false as argument. If you set InitializationData::executor, the executor determines the thread that executes this function in the asynchronous case.
context	The request context.

Returns

A function that can be called to cancel the invocation locally.
