jdk.lang.management.RuntimeMXBean — clojure-interop/java.lang.management 1.0.5

The management interface for the runtime system of the Java virtual machine.

A Java virtual machine has a single instance of the implementation class of this interface. This instance implementing this interface is an MXBean that can be obtained by calling the ManagementFactory.getRuntimeMXBean() method or from the platform MBeanServer method.

The ObjectName for uniquely identifying the MXBean for the runtime system within an MBeanServer is:

java.lang:type=Runtime

It can be obtained by calling the PlatformManagedObject.getObjectName() method.

This interface defines several convenient methods for accessing system properties about the Java virtual machine.

boot-class-path-supported? clj

(boot-class-path-supported? this)

Tests if the Java virtual machine supports the boot class path mechanism used by the bootstrap class loader to search for class files.

returns: true if the Java virtual machine supports the class path mechanism; false otherwise. - boolean

get-boot-class-path clj

(get-boot-class-path this)

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.

returns: the boot class path. - java.lang.String

throws: java.lang.UnsupportedOperationException - if the Java virtual machine does not support this operation.

get-class-path clj

(get-class-path this)

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.

returns: the Java class path. - java.lang.String

throws: java.lang.SecurityException - if a security manager exists and its checkPropertiesAccess method doesn't allow access to this system property.

get-input-arguments clj

(get-input-arguments this)

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[].

returns: a list of String objects; each element is an argument passed to the Java virtual machine. - java.util.List<java.lang.String>

throws: java.lang.SecurityException - if a security manager exists and the caller does not have ManagementPermission("monitor").

get-library-path clj

(get-library-path this)

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.

returns: the Java library path. - java.lang.String

throws: java.lang.SecurityException - if a security manager exists and its checkPropertiesAccess method doesn't allow access to this system property.

get-management-spec-version clj

(get-management-spec-version this)

Returns the version of the specification for the management interface implemented by the running Java virtual machine.

returns: the version of the specification for the management interface implemented by the running Java virtual machine. - java.lang.String

get-name clj

(get-name this)

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.

returns: the name representing the running Java virtual machine. - java.lang.String

get-spec-name clj

(get-spec-name this)

Returns the Java virtual machine specification name. This method is equivalent to System.getProperty("java.vm.specification.name").

returns: the Java virtual machine specification name. - java.lang.String

throws: java.lang.SecurityException - if a security manager exists and its checkPropertiesAccess method doesn't allow access to this system property.

get-spec-vendor clj

(get-spec-vendor this)

Returns the Java virtual machine specification vendor. This method is equivalent to System.getProperty("java.vm.specification.vendor").

returns: the Java virtual machine specification vendor. - java.lang.String

throws: java.lang.SecurityException - if a security manager exists and its checkPropertiesAccess method doesn't allow access to this system property.

get-spec-version clj

(get-spec-version this)

Returns the Java virtual machine specification version. This method is equivalent to System.getProperty("java.vm.specification.version").

returns: the Java virtual machine specification version. - java.lang.String

throws: java.lang.SecurityException - if a security manager exists and its checkPropertiesAccess method doesn't allow access to this system property.

get-start-time clj

(get-start-time this)

Returns the start time of the Java virtual machine in milliseconds. This method returns the approximate time when the Java virtual machine started.

returns: start time of the Java virtual machine in milliseconds. - long

get-system-properties clj

(get-system-properties this)

Returns a map of names and values of all system properties. This method calls 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<String,String> is TabularData with two items in each row as follows:

Item Name Item Type

key String

value String

returns: a map of names and values of all system properties. - java.util.Map<java.lang.String,java.lang.String>

throws: java.lang.SecurityException - if a security manager exists and its checkPropertiesAccess method doesn't allow access to the system properties.

get-uptime clj

(get-uptime this)

Returns the uptime of the Java virtual machine in milliseconds.

returns: uptime of the Java virtual machine in milliseconds. - long

get-vm-name clj

(get-vm-name this)

Returns the Java virtual machine implementation name. This method is equivalent to System.getProperty("java.vm.name").

returns: the Java virtual machine implementation name. - java.lang.String

throws: java.lang.SecurityException - if a security manager exists and its checkPropertiesAccess method doesn't allow access to this system property.

get-vm-vendor clj

(get-vm-vendor this)

Returns the Java virtual machine implementation vendor. This method is equivalent to System.getProperty("java.vm.vendor").

returns: the Java virtual machine implementation vendor. - java.lang.String

throws: java.lang.SecurityException - if a security manager exists and its checkPropertiesAccess method doesn't allow access to this system property.

get-vm-version clj

(get-vm-version this)

Returns the Java virtual machine implementation version. This method is equivalent to System.getProperty("java.vm.version").

returns: the Java virtual machine implementation version. - java.lang.String

throws: java.lang.SecurityException - if a security manager exists and its checkPropertiesAccess method doesn't allow access to this system property.
