    • Method Detail

      • getTotalLoadedClassCount

        long getTotalLoadedClassCount()
        Returns the total number of classes that have been loaded since the Java virtual machine has started execution.
        Returns:
        the total number of classes loaded.
      • getLoadedClassCount

        int getLoadedClassCount()
        Returns the number of classes that are currently loaded in the Java virtual machine.
        Returns:
        the number of currently loaded classes.
      • getUnloadedClassCount

        long getUnloadedClassCount()
        Returns the total number of classes unloaded since the Java virtual machine has started execution.
        Returns:
        the total number of unloaded classes.
      • isVerbose

        boolean isVerbose()
        Tests if the verbose output for the class loading system is enabled.
        Returns:
        true if the verbose output for the class loading system is enabled; false otherwise.
      • setVerbose

        void setVerbose​(boolean value)
        Enables or disables the verbose output for the class loading system. The verbose output information and the output stream to which the verbose information is emitted are implementation dependent. Typically, a Java virtual machine implementation prints a message each time a class file is loaded.

        This method can be called by multiple threads concurrently. Each invocation of this method enables or disables the verbose output globally.

        Parameters:
        value - true to enable the verbose output; false to disable.
        Throws:
        SecurityException - if a security manager exists and the caller does not have ManagementPermission("control").
