Examples of VMReply

com.sun.cldchi.tools.memoryprofiler.jdwp.VMReply
The VMReply declares interface between transport layer and data providing layer of the memory profiler. It allows reading integet and string values from the packet sent by the VM. The instances of this interface are provided by VMConnection. @see com.sun.cldchi.tools.memoryprofiler.jdwp.VMConnection
