Subject [jira] Updated: (HARMONY-3037) [classlib][nio]DatagramChannelImpl and SocketChannelImpl lack support for direct byte buffer
Date Mon, 29 Jan 2007 04:07:49 GMT

     [ https://issues.apache.org/jira/browse/HARMONY-3037?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Leo Li updated HARMONY-3037:
----------------------------

    Description: As spec says, "Given a direct byte buffer, the Java virtual machine will
make a best effort to perform native I/O operations directly upon it. That is, it will attempt
to avoid copying the buffer's content to (or from) an intermediate buffer before (or after)
each invocation of one of the underlying operating system's native I/O operation". However,
in Harmony nio, DatagramChannelImpl and SocketChannelImpl do not differentiate whether the
byte buffer is direct or not.  (was: As spec says, "Given a direct byte buffer, the Java virtual
machine will make a best effort to perform native I/O operations directly upon it. That is,
it will attempt to avoid copying the buffer's content to (or from) an intermediate buffer
before (or after) each invocation of one of the underlying operating system's native I/O operation".
However, in Harmony nio, DatagramChannelImpl does not differentiate whether the byte buffer
is direct or not.)
        Summary: [classlib][nio]DatagramChannelImpl  and SocketChannelImpl lack support for
direct byte buffer   (was: [classlib][nio]DatagramChannelImpl  and SocketChannelImpl lacks
support for direct byte buffer )
