public boolean isVerbose()

Implements java.lang.management.ClassLoadingMXBean.isVerbose.

Doc from java.lang.management.ClassLoadingMXBean.isVerbose.

Tests if the verbose output for the class loading system is enabled.

setVerboseback to summary
public void setVerbose(boolean value)

Implements java.lang.management.ClassLoadingMXBean.setVerbose.

Doc from java.lang.management.ClassLoadingMXBean.setVerbose.

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.
