readAsync()

virtual void IceGrid::AsyncFileIterator::readAsync ( std::int32_t size, std::function< void(bool returnValue, const ::Ice::StringSeq &lines)> response, std::function< void(std::exception_ptr)> exception, const Ice::Current & current )

pure virtual

Read lines from the log file.

Parameters

size	Specifies the maximum number of bytes to be received. The server will ensure that the returned message doesn't exceed the given size.
response	The response callback. It accepts: returnValue true if EOF is encountered. lines The lines read from the file. If there was nothing to read from the file since the last call to read, an empty sequence is returned. The last line of the sequence is always incomplete (and therefore no newline character should be added when writing the last line to the to the output device).
exception	The exception callback.
current	The Current object of the incoming request.

Exceptions

IceGrid::FileNotAvailableException

Thrown when the implementation failed to read from the file.
