Everywhere including examples, external interop APIs, bindings generators
code and in other valuable places. A couple of `interface{}` usages are
intentionally left in the CHANGELOG.md, documentation and tests.

// InvokeAndPackIteratorResults creates a script containing System.Contract.Call
|
|
// of the specified contract with the specified arguments. It assumes that the
|
|
// specified operation will return iterator. The script traverses the resulting
|
|
// iterator, packs all its values into array and pushes the resulting array on
|
|
// stack. Constructed script is invoked via `invokescript` JSON-RPC API using
|
|
// the provided signers. The result of the script invocation contains single array
|
|
// stackitem on stack if invocation HALTed. InvokeAndPackIteratorResults can be
|
|
// used to interact with JSON-RPC server where iterator sessions are disabled to
|
|
// retrieve iterator values via single `invokescript` JSON-RPC call. It returns
|
|
// maxIteratorResultItems items at max which is set to
|
|
// config.DefaultMaxIteratorResultItems by default.

//
|
|
// Deprecated: please use more convenient and powerful invoker.Invoker interface with
|
|
// CallAndExpandIterator method. This method will be removed in future versions.
