In-Depth Information
Equivalent to
enumerate(threadsInGroup,true)
.
public int
activeGroupCount()
Like
activeCount
, but counts groups, instead of threads, in all
subgroups. "Active" means "existing." There is no concept of
an inactive group; the term "active" is used for consistency
with
activeCount
.
public int
enumerate(ThreadGroup[] groupsInGroup, boolean recurse)
Like the similar
enumerate
method for threads, but fills an array
of
ThreadGroup
references instead of
THRead
references.
public int
enumerate(ThreadGroup[] groupsInGroup)
Equivalent to
enumerate(groupsInGroup,true)
.
You can also use a
ThreadGroup
to manage threads in the group. Invoking
interrupt
on a group invokes the
interrupt
method on each thread in the
group, including threads in all subgroups. This method is the only way
to use a
ThreadGroup
to directly affect threadsthere used to be others but
they have been deprecated.
There are also two static methods in the
Thread
class to act on the cur-
rent thread's group. They are shorthands for invoking
currentThread
, in-
voking
getThreadGroup
on that thread, and then invoking the method on
that group.
public static int
activeCount()
Returns the number of active threads in the current thread's
ThreadGroup
.
public static int
enumerate(Thread[] threadsInGroup)
