Method Detail

getBootClassPathback to summary
public String getBootClassPath()

Implements java.lang.management.RuntimeMXBean.getBootClassPath.

Doc from java.lang.management.RuntimeMXBean.getBootClassPath.

Returns the boot class path that is used by the bootstrap class loader to search for class files.

Multiple paths in the boot class path are separated by the path separator character of the platform on which the Java virtual machine is running.

A Java virtual machine implementation may not support the boot class path mechanism for the bootstrap class loader to search for class files. The isBootClassPathSupported method can be used to determine if the Java virtual machine supports this method.

getClassPathback to summary
public String getClassPath()

Implements java.lang.management.RuntimeMXBean.getClassPath.

Doc from java.lang.management.RuntimeMXBean.getClassPath.

Returns the Java class path that is used by the system class loader to search for class files. This method is equivalent to System.getProperty("java.class.path").

Multiple paths in the Java class path are separated by the path separator character of the platform of the Java virtual machine being monitored.

getInputArgumentsback to summary
public List<String> getInputArguments()

Implements java.lang.management.RuntimeMXBean.getInputArguments.

Doc from java.lang.management.RuntimeMXBean.getInputArguments.

Returns the input arguments passed to the Java virtual machine which does not include the arguments to the main method. This method returns an empty list if there is no input argument to the Java virtual machine.

Some Java virtual machine implementations may take input arguments from multiple different sources: for examples, arguments passed from the application that launches the Java virtual machine such as the 'java' command, environment variables, configuration files, etc.

Typically, not all command-line options to the 'java' command are passed to the Java virtual machine. Thus, the returned input arguments may not include all command-line options.

MBeanServer access:
The mapped type of List<String> is String[].

getLibraryPathback to summary
public String getLibraryPath()

Implements java.lang.management.RuntimeMXBean.getLibraryPath.

Doc from java.lang.management.RuntimeMXBean.getLibraryPath.

Returns the Java library path. This method is equivalent to System.getProperty("java.library.path").

Multiple paths in the Java library path are separated by the path separator character of the platform of the Java virtual machine being monitored.

public String getName()

Implements java.lang.management.RuntimeMXBean.getName.

Doc from java.lang.management.RuntimeMXBean.getName.

Returns the name representing the running Java virtual machine. The returned name string can be any arbitrary string and a Java virtual machine implementation can choose to embed platform-specific useful information in the returned name string. Each running virtual machine could have a different name.

getObjectNameback to summary
