Expand description

Select a GC plan for MMTk.

Variants§

§

NoGC

Allocation only without a collector. This is usually used for debugging. Similar to OpenJDK epsilon (https://openjdk.org/jeps/318).

§

SemiSpace

A semi-space collector, which divides the heap into two spaces and copies the live objects into the other space for every GC.

§

GenCopy

A generational collector that uses a copying nursery, and the semi-space policy as its mature space.

§

GenImmix

A generational collector that uses a copying nursery, and Immix as its mature space.

§

MarkSweep

A mark-sweep collector, which marks live objects and sweeps dead objects during GC.

§

PageProtect

A debugging collector that allocates memory at page granularity, and protects pages for dead objects to prevent future access.

§

Immix

A mark-region collector that allows an opportunistic defragmentation mechanism.

§

MarkCompact

A mark-compact collector that marks objects and performs Cheney-style copying.

§

StickyImmix

An Immix collector that uses a sticky mark bit to allow generational behaviors without a copying nursery.
