This patch, already applied to upstream classpath, adds another type of
Value for JDWP. Since regular Object values and Array values have
different tags, this patch adds the
classpath/gnu/classpath/jdwp/value/ArrayValue class to handle Array
values for JDWP. This also adds checks in natVMFrame.cc to use these
new Values when getting and setting array objects.
ChangeLog
2007-04-09 Kyle Galloway <kgallowa@redhat.com>
* classpath/gnu/classpath/jdwp/value/ArrayValue.java: New file.
* classpath/lib/gnu/classpath/jdwp/value/ArrayValue.class: New file.
* gnu/classpath/jdwp/ArrayValue.h: New file.
* gnu/classpath/jdwp/natVMFrame.cc (getValue): Add array case.
(setValue): Ditto.
Questions/comments/concerns?
Thanks,
Kyle
