Struct mmtk::plan::generational::barrier::GenObjectBarrierSemantics

pub struct GenObjectBarrierSemantics<VM: VMBinding, P: GenerationalPlanExt<VM> + PlanTraceObject<VM>> {
    mmtk: &'static MMTK<VM>,
    plan: &'static P,
    modbuf: VectorQueue<ObjectReference>,
    region_modbuf: VectorQueue<VM::VMMemorySlice>,
}

Fields

mmtk: &'static MMTK<VM>

MMTk instance

plan: &'static P

Generational plan

modbuf: VectorQueue<ObjectReference>

Object modbuf. Contains a list of objects that may contain pointers to the nursery space.

region_modbuf: VectorQueue<VM::VMMemorySlice>

Array-copy modbuf. Contains a list of sub-arrays or array slices that may contain pointers to the nursery space.

Implementations

impl<VM: VMBinding, P: GenerationalPlanExt<VM> + PlanTraceObject<VM>> GenObjectBarrierSemantics<VM, P>

pub fn new(mmtk: &'static MMTK<VM>, plan: &'static P) -> Self

fn flush_modbuf(&mut self)

fn flush_region_modbuf(&mut self)

Trait Implementations

impl<VM: VMBinding, P: GenerationalPlanExt<VM> + PlanTraceObject<VM>> BarrierSemantics for GenObjectBarrierSemantics<VM, P>

type VM = VM

fn flush(&mut self)

Flush thread-local buffers or remembered sets. Normally this is called by the slow-path implementation whenever the thread-local buffers are full. This will also be called externally by the VM, when the thread is being destroyed.

fn object_reference_write_slow( &mut self, src: ObjectReference, _slot: VM::VMSlot, _target: Option<ObjectReference> )

Slow-path call for object field write operations.

fn memory_region_copy_slow( &mut self, _src: VM::VMMemorySlice, dst: VM::VMMemorySlice )

Slow-path call for mempry slice copy operations. For example, array-copy operations.

fn object_probable_write_slow(&mut self, obj: ObjectReference)

Object will probably be modified
