Detect end of stream with onNewData #462

Closed emendo-web closed 11 months ago

emendo-web commented 1 year ago

Hello,

Thank you for this package.

From what I could see of this package how can I know that my data has all arrived before processing it?

With the onNewData method I receive data substitution

Would there be a solution to know when all the bytes received?

InputStream returned -1 if reading data is complete

Or is the only solution to detect a delimiter character and close the stream when found ?

Thanks, Cyril
