From class java.lang.Object

Object	clone() Creates and returns a copy of this object.
boolean	equals(Object obj) Indicates whether some other object is "equal to" this one.
void	finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
final Class<?>	getClass() Returns the runtime class of this `Object`.
int	hashCode() Returns a hash code value for the object.
final void	notify() Wakes up a single thread that is waiting on this object's monitor.
final void	notifyAll() Wakes up all threads that are waiting on this object's monitor.
String	toString() Returns a string representation of the object.
final void	wait() Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
final void	wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
final void	wait(long timeout) Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.

abstract boolean	isCollected() Determines if this object has been garbage collected in the target VM.
abstract ThreadReference	owningThread() Returns an `ThreadReference` for the thread, if any, which currently owns this object's monitor.
abstract ReferenceType	referenceType() Gets the `ReferenceType` that mirrors the type of this object.
abstract List<ObjectReference>	referringObjects(long maxReferrers) Returns objects that directly reference this object.
abstract void	setValue(Field field, Value value) Sets the value of a given instance or static field in this object.

Public Methods

public String name ()

Returns the name of this thread group.

Returns

the string containing the thread group name.

public ThreadGroupReference parent ()

Returns the parent of this thread group.

Returns

a ThreadGroupReference mirroring the parent of this thread group in the target VM, or null if this is a top-level thread group.

public void resume ()

Resumes all threads in this thread group. Each thread in this group and in all of its subgroups will be resumed as described in resume().

public void suspend ()

Suspends all threads in this thread group. Each thread in this group and in all of its subgroups will be suspended as described in suspend(). This is not guaranteed to be an atomic operation; if the target VM is not interrupted at the time this method is called, it is possible that new threads will be created between the time that threads are enumerated and all of them have been suspended.

public List<ThreadGroupReference> threadGroups ()

Returns a List containing each active ThreadGroupReference in this thread group. Only the active thread groups in this immediate thread group (and not its subgroups) are returned. See java.lang.ThreadGroup for information about 'active' ThreadGroups.

Returns

a List of ThreadGroupReference objects mirroring the active thread groups from this thread group in the target VM.

public List<ThreadReference> threads ()

Returns a List containing a ThreadReference for each live thread in this thread group. Only the live threads in this immediate thread group (and not its subgroups) are returned. A thread is alive if it has been started and has not yet been stopped.

Returns

a List of ThreadReference objects mirroring the live threads from this thread group in the target VM.

public String toString ()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
