Interface NativeMemoryCategory



  • public interface NativeMemoryCategory
    This class contains information about the different areas, or categories, in the JVM that are using native memory. Categories might include, for example, JIT, Threads, or Class Libraries. Categories have a hierarchy, for example, the JRE category contains the Class Libraries category, which in turn contains the VM Class Libraries category.
