Clarification needed: Should JsonWriter write methods close the underlying writer/stream

[glassfishrobot]

Hi,

I'm evaluating Johnzon [1] as JSON-P implementation. My concern is that Johnzon's JsonWriter implementation closes the writer/stream after invocation of any of the write*() methods: [2]. The javadoc does not explicitly mention that the stream/writer has to be closed, but says that the write* methods are one-time use only, which might be interpreted that they close the stream/writer.

Please clarify if it's ok for the write* methods to close the underlying stream/writer.

Kind regards, Svetlin

@m0mus Commented You are right, JSON-P specification only requires that write* methods called only once for a writer instance. It doesn't require closing the stream though, so it's up to implementations.

JSON-P RI doesn't close the stream. It flushes it on each write and throws an exception if another write attempt happens.
