Interface GarbageCollectorMXBean
- MemoryManagerMXBean
- GarbageCollectorMXBeanImpl
Provides access to information about the garbage collectors
of the virtual machine. Garbage collectors are responsible
for removing unreferenced objects from memory. A garbage
collector is a type of memory manager, so this interface
is combined with that of generic memory managers. An instance
of this bean for each garbage collector is obtained by calling
ManagementFactory.getGarbageCollectorMXBeans().
long | getCollectionCount()- Returns the number of collections the garbage collector
represented by this bean has made.
|
long | getCollectionTime()- Returns the accumulated number of milliseconds this garbage
collector has spent freeing the memory used by unreferenced
objects.

getCollectionCount
public long getCollectionCount()
Returns the number of collections the garbage collector
represented by this bean has made. -1 is returned if the
collection count is undefined.
- the number of collections made, or -1 if this is
undefined.
getCollectionTime
public long getCollectionTime()
Returns the accumulated number of milliseconds this garbage
collector has spent freeing the memory used by unreferenced
objects. -1 is returned if the collection time is undefined.
Note that the accumulated time may not change, even when the
collection count increases, if the time taken is sufficiently
short; this depends on the resolution of the timer used.
- the accumulated number of milliseconds spent collecting,
or -1 if this is undefined.
