created.null

indicate that the data entry should not be written.java.io.IOException
void close() throws java.io.IOException
NonClosingDataEntryWriter
can avoid closing
a branch prematurely.
For cycles, implementations must perform any custom behavior, then
delegate close()
invocations, and only finally clean up. It is
possible that delegates call createOutputStream(DataEntry)
while close()
is in progress.close
