[cp-patches] [Patch] java.nio.channels.Channels improved

[Michael Koch]

Hi list,


I commited the attached patch to implement optimized handling of file
channels in java.nio.channels.Channels. The default implementation
returns a FileInputStream with newInputStream() and a FileOutputStream
for newOutputStream() for FileChannel objects given to them. It uses
reflection to instantiate the needed stream objects in this case. VMs
can overwrite this easily, e.g. GCJ will do this much more easily using
CNI without the need for reflection. The functionality was proved by
new mauve testcases.

        * java/nio/channels/Channels.java
        (newInputStream(ReadableByteChannel)):
        Call VMChannels.newInputStream(ReadableByteChannel).
        (newOutputStream(WritableByteChannel):
        Call VMChannels.newOutputStream(WritableByteChannel).
        (newInputStream(FileChannelImpl)): Removed.
        (newOutputStream(FileChannelImpl)): Likewise.
        * vm/reference/java/nio/channels/VMChannels.java: New file.
        * native/jni/java-nio/Makefile.am:
        * native/jni/java-nio/java_nio_channels_Channels.c,
