Detailed Description

Options specifying Heap properties (e.g. custom spaces) when initializing a heap through Heap::Create().

Definition at line 118 of file heap.h.

Member Function Documentation

◆ Default()

static HeapOptions Default ( )
inlinestatic

Creates reasonable defaults for instantiating a Heap.

Returns
the HeapOptions that can be passed to Heap::Create().

Definition at line 124 of file heap.h.

Field Documentation

◆ custom_spaces

std::vector<std::unique_ptr<CustomSpaceBase> > custom_spaces

Custom spaces added to heap are required to have indices forming a numbered sequence starting at 0, i.e., their kSpaceIndex must correspond to the index they reside in the vector.

Definition at line 131 of file heap.h.

◆ marking_support

Specifies which types of marking are supported by the heap.

Definition at line 146 of file heap.h.

◆ resource_constraints

ResourceConstraints resource_constraints

Resource constraints specifying various properties that the internal GC scheduler follows.

Definition at line 157 of file heap.h.

◆ stack_support

Specifies whether conservative stack scan is supported. When conservative stack scan is not supported, the collector may try to invoke garbage collections using non-nestable task, which are guaranteed to have no interesting stack, through the provided Platform. If such tasks are not supported by the Platform, the embedder must take care of invoking the GC through ForceGarbageCollectionSlow().

Definition at line 141 of file heap.h.

◆ sweeping_support

Specifies which types of sweeping are supported by the heap.

Definition at line 151 of file heap.h.
