示例1: ArrayLength
void
MsaaIdGenerator::ReleaseContentProcessIDFor(dom::ContentParentId aIPCContentProcessID)
{
MOZ_ASSERT(XRE_IsParentProcess() && NS_IsMainThread());
if (!sContentParentIdMap) {
// Since Content IDs are generated lazily, ContentParent might attempt
// to release an ID that was never allocated to begin with.
return;
}
Maybe<uint32_t> mapping = sContentParentIdMap->GetAndRemove(aIPCContentProcessID);
if (!mapping) {
// Since Content IDs are generated lazily, ContentParent might attempt
// to release an ID that was never allocated to begin with.
return;
}
uint32_t index = mapping.ref() / kBitsPerElement;
MOZ_ASSERT(index < ArrayLength(sContentProcessIdBitmap));
uint64_t mask = 1ULL << (mapping.ref() % kBitsPerElement);
MOZ_ASSERT(sContentProcessIdBitmap[index] & mask);
sContentProcessIdBitmap[index] &= ~mask;
