getBootClassPath
public String getBootClassPath()
Returns the boot classpath used by the virtual machine. This
value follows the standard path syntax used by the underlying
operating system (e.g. directories separated by ':' on UNIX
or ';' on Windows).
Supplying this value is optional. Users should check the
return value of
isBootClassPathSupported() prior to
calling this method.
- getBootClassPath in interface RuntimeMXBean
- the boot classpath of the virtual machine, if supported.
getClassPath
public String getClassPath()
Returns the classpath used by the system classloader. This
is equivalent to obtaining the
java.class.path
property via
System.getProperty(String). This value
follows the standard path syntax used by the underlying operating
system (e.g. directories separated by ':' on UNIX or ';' on
Windows).
- getClassPath in interface RuntimeMXBean
- the classpath used by the system class loader.
SecurityException - if a security manager exists which
prevents access to the classpath
property.
getInputArguments
public List<E> getInputArguments()
Returns a list of the arguments given to the virtual machine,
excluding those that apply to the main() method
of the class file being executed. These may not just be those
specified at the command line, but may also include arguments
from environment variables, configuration files, etc. All
command line arguments may not reach the virtual machine, so
these are not included in this list.
- getInputArguments in interface RuntimeMXBean
- a list of arguments passed to the virtual machine.
SecurityException - if a security manager exists and
denies ManagementPermission("monitor").
getLibraryPath
public String getLibraryPath()
Returns the library path. This is equivalent to obtaining the
java.library.path property via
System.getProperty(String). This value follows the
standard path syntax used by the underlying operating
system (e.g. directories separated by ':' on UNIX or ';' on
Windows).
- getLibraryPath in interface RuntimeMXBean
SecurityException - if a security manager exists which
prevents access to the library path
property.
getName
public String getName()
Returns the name of this virtual machine. The content
of this property is left up to the developer of the
virtual machine. It may include a number of system
attributes and may differ between instances of the
same virtual machine (for example, it might include
the process identifier or the host name of the machine
on which it is running). The intention is that this
name refers to the precise entity that the other data
supplied by this bean refers to, rather than the VM
in general.
- getName in interface RuntimeMXBean
- the name of this virtual machine.
getStartTime
public long getStartTime()
Returns the approximate start time of the virtual machine
in milliseconds.
- getStartTime in interface RuntimeMXBean
- the start time of the virtual machine.
getUptime
public long getUptime()
Returns the uptime of the virtual machine in milliseconds.
- getUptime in interface RuntimeMXBean
- the uptime of the virtual machine.
