readAsync() [1/2]

std::future< std::tuple< bool, ::Ice::StringSeq > > IceGrid::FileIteratorPrx::readAsync ( std::int32_t size, const Ice::Context & context = Ice::noExplicitContext ) const

nodiscard

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.
context	The request context.

Returns

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

• 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).
