Member Data Documentation

◆ add_histogram_sample_callback

AddHistogramSampleCallback v8::Isolate::CreateParams::add_histogram_sample_callback = nullptr

Definition at line 315 of file v8-isolate.h.

◆ allow_atomics_wait

bool v8::Isolate::CreateParams::allow_atomics_wait = true

Whether calling Atomics.wait (a function that may block) is allowed in this isolate. This can also be configured via SetAllowAtomicsWait.

Definition at line 341 of file v8-isolate.h.

◆ array_buffer_allocator

ArrayBuffer::Allocator* v8::Isolate::CreateParams::array_buffer_allocator = nullptr

The ArrayBuffer::Allocator to use for allocating and freeing the backing store of ArrayBuffers.

If the shared_ptr version is used, the Isolate instance and every |BackingStore| allocated using this allocator hold a std::shared_ptr to the allocator, in order to facilitate lifetime management for the allocator instance.

Definition at line 326 of file v8-isolate.h.

◆ array_buffer_allocator_shared

std::shared_ptr<ArrayBuffer::Allocator> v8::Isolate::CreateParams::array_buffer_allocator_shared

Definition at line 327 of file v8-isolate.h.

◆ code_event_handler

JitCodeEventHandler v8::Isolate::CreateParams::code_event_handler = nullptr

Allows the host application to provide the address of a function that is notified each time code is added, moved or removed.

Definition at line 289 of file v8-isolate.h.

◆ constraints

ResourceConstraints v8::Isolate::CreateParams::constraints

ResourceConstraints to use for the new Isolate.

Definition at line 294 of file v8-isolate.h.

◆ counter_lookup_callback

CounterLookupCallback v8::Isolate::CreateParams::counter_lookup_callback = nullptr

Enables the host application to provide a mechanism for recording statistics counters.

Definition at line 306 of file v8-isolate.h.

◆ cpp_heap

CppHeap* v8::Isolate::CreateParams::cpp_heap = nullptr

A CppHeap used to construct the Isolate. V8 takes ownership of the CppHeap passed this way.

Definition at line 361 of file v8-isolate.h.

◆ create_histogram_callback

CreateHistogramCallback v8::Isolate::CreateParams::create_histogram_callback = nullptr

Enables the host application to provide a mechanism for recording histograms. The CreateHistogram function returns a histogram which will later be passed to the AddHistogramSample function.

Definition at line 314 of file v8-isolate.h.

◆ embedder_wrapper_object_index

int v8::Isolate::CreateParams::embedder_wrapper_object_index = -1

Definition at line 349 of file v8-isolate.h.

◆ embedder_wrapper_type_index

int v8::Isolate::CreateParams::embedder_wrapper_type_index = -1

The following parameters describe the offsets for addressing type info for wrapped API objects and are used by the fast C API (for details see v8-fast-api-calls.h).

Definition at line 348 of file v8-isolate.h.

◆ external_references

const intptr_t* v8::Isolate::CreateParams::external_references = nullptr

Specifies an optional nullptr-terminated array of raw addresses in the embedder that V8 can match against during serialization and use for deserialization. This array and its content must stay valid for the entire lifetime of the isolate.

Definition at line 335 of file v8-isolate.h.

◆ fatal_error_callback

FatalErrorCallback v8::Isolate::CreateParams::fatal_error_callback = nullptr

Callbacks to invoke in case of fatal or OOM errors.

Definition at line 354 of file v8-isolate.h.

◆ oom_error_callback

OOMErrorCallback v8::Isolate::CreateParams::oom_error_callback = nullptr

Definition at line 355 of file v8-isolate.h.

◆ snapshot_blob

const StartupData* v8::Isolate::CreateParams::snapshot_blob = nullptr

Explicitly specify a startup snapshot blob. The embedder owns the blob. The embedder must ensure that the snapshot is from a trusted source.

Definition at line 300 of file v8-isolate.h.
