Methods Summary
public java.lang.String	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 {@link #isBootClassPathSupported} method can be used to determine if the Java virtual machine supports this method. return the boot class path. throws java.lang.UnsupportedOperationException if the Java virtual machine does not support this operation. throws java.lang.SecurityException if a security manager exists and the caller does not have ManagementPermission("monitor").
public java.lang.String	getClassPath() Returns the Java class path that is used by the system class loader to search for class files. This method is equivalent to {@link System#getProperty 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. return the Java class path. throws java.lang.SecurityException if a security manager exists and its checkPropertiesAccess method doesn't allow access to this system property. see java.lang.SecurityManager#checkPropertyAccess(java.lang.String) see java.lang.System#getProperty
public java.util.List	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 is String[]. return a list of String objects; each element is an argument passed to the Java virtual machine. throws java.lang.SecurityException if a security manager exists and the caller does not have ManagementPermission("monitor").
public java.lang.String	getLibraryPath() Returns the Java library path. This method is equivalent to {@link System#getProperty 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. return the Java library path. throws java.lang.SecurityException if a security manager exists and its checkPropertiesAccess method doesn't allow access to this system property. see java.lang.SecurityManager#checkPropertyAccess(java.lang.String) see java.lang.System#getProperty
public java.lang.String	getManagementSpecVersion() Returns the version of the specification for the management interface implemented by the running Java virtual machine. return the version of the specification for the management interface implemented by the running Java virtual machine.
public java.lang.String	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. return the name representing the running Java virtual machine.
public java.lang.String	getSpecName() Returns the Java virtual machine specification name. This method is equivalent to {@link System#getProperty System.getProperty("java.vm.specification.name")}. return the Java virtual machine specification name. throws java.lang.SecurityException if a security manager exists and its checkPropertiesAccess method doesn't allow access to this system property. see java.lang.SecurityManager#checkPropertyAccess(java.lang.String) see java.lang.System#getProperty
public java.lang.String	getSpecVendor() Returns the Java virtual machine specification vendor. This method is equivalent to {@link System#getProperty System.getProperty("java.vm.specification.vendor")}. return the Java virtual machine specification vendor. throws java.lang.SecurityException if a security manager exists and its checkPropertiesAccess method doesn't allow access to this system property. see java.lang.SecurityManager#checkPropertyAccess(java.lang.String) see java.lang.System#getProperty
public java.lang.String	getSpecVersion() Returns the Java virtual machine specification version. This method is equivalent to {@link System#getProperty System.getProperty("java.vm.specification.version")}. return the Java virtual machine specification version. throws java.lang.SecurityException if a security manager exists and its checkPropertiesAccess method doesn't allow access to this system property. see java.lang.SecurityManager#checkPropertyAccess(java.lang.String) see java.lang.System#getProperty
public long	getStartTime() Returns the start time of the Java virtual machine in milliseconds. This method returns the approximate time when the Java virtual machine started. return start time of the Java virtual machine in milliseconds.
public java.util.Map	getSystemProperties() Returns a map of names and values of all system properties. This method calls {@link System#getProperties} to get all system properties. Properties whose name or value is not a String are omitted. MBeanServer access: The mapped type of Map is {@link javax.management.openmbean.TabularData TabularData} with two items in each row as follows: Item Name Item Type key String value String return a map of names and values of all system properties. throws java.lang.SecurityException if a security manager exists and its checkPropertiesAccess method doesn't allow access to the system properties.
public long	getUptime() Returns the uptime of the Java virtual machine in milliseconds. return uptime of the Java virtual machine in milliseconds.
public java.lang.String	getVmName() Returns the Java virtual machine implementation name. This method is equivalent to {@link System#getProperty System.getProperty("java.vm.name")}. return the Java virtual machine implementation name. throws java.lang.SecurityException if a security manager exists and its checkPropertiesAccess method doesn't allow access to this system property. see java.lang.SecurityManager#checkPropertyAccess(java.lang.String) see java.lang.System#getProperty
public java.lang.String	getVmVendor() Returns the Java virtual machine implementation vendor. This method is equivalent to {@link System#getProperty System.getProperty("java.vm.vendor")}. return the Java virtual machine implementation vendor. throws java.lang.SecurityException if a security manager exists and its checkPropertiesAccess method doesn't allow access to this system property. see java.lang.SecurityManager#checkPropertyAccess(java.lang.String) see java.lang.System#getProperty
public java.lang.String	getVmVersion() Returns the Java virtual machine implementation version. This method is equivalent to {@link System#getProperty System.getProperty("java.vm.version")}. return the Java virtual machine implementation version. throws java.lang.SecurityException if a security manager exists and its checkPropertiesAccess method doesn't allow access to this system property. see java.lang.SecurityManager#checkPropertyAccess(java.lang.String) see java.lang.System#getProperty
public boolean	isBootClassPathSupported() Tests if the Java virtual machine supports the boot class path mechanism used by the bootstrap class loader to search for class files. return true if the Java virtual machine supports the class path mechanism; false otherwise.
