Field Documentation

◆ add_histogram_sample_callback

AddHistogramSampleCallback add_histogram_sample_callback = nullptr

Definition at line 244 of file v8-isolate.h.

◆ allow_atomics_wait

bool 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 270 of file v8-isolate.h.

◆ array_buffer_allocator

ArrayBuffer::Allocator* 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 255 of file v8-isolate.h.

◆ array_buffer_allocator_shared

std::shared_ptr<ArrayBuffer::Allocator> array_buffer_allocator_shared

Definition at line 256 of file v8-isolate.h.

◆ code_event_handler

JitCodeEventHandler 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 218 of file v8-isolate.h.

◆ constraints

ResourceConstraints constraints

ResourceConstraints to use for the new Isolate.

Definition at line 223 of file v8-isolate.h.

◆ counter_lookup_callback

CounterLookupCallback counter_lookup_callback = nullptr

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

Definition at line 235 of file v8-isolate.h.

◆ create_histogram_callback

CreateHistogramCallback 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 243 of file v8-isolate.h.

◆ embedder_wrapper_object_index

int embedder_wrapper_object_index = -1

Definition at line 283 of file v8-isolate.h.

◆ embedder_wrapper_type_index

int 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 282 of file v8-isolate.h.

◆ experimental_attach_to_shared_isolate

Isolate* experimental_attach_to_shared_isolate = nullptr

The following parameter is experimental and may change significantly. This is currently for internal testing.

Definition at line 295 of file v8-isolate.h.

◆ external_references

const intptr_t* 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 264 of file v8-isolate.h.

◆ fatal_error_callback

FatalErrorCallback fatal_error_callback = nullptr

Callbacks to invoke in case of fatal or OOM errors.

Definition at line 288 of file v8-isolate.h.

◆ only_terminate_in_safe_scope

bool only_terminate_in_safe_scope = false

Termination is postponed when there is no active SafeForTerminationScope.

Definition at line 275 of file v8-isolate.h.

◆ oom_error_callback

OOMErrorCallback oom_error_callback = nullptr

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

◆ snapshot_blob

StartupData* 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 229 of file v8-isolate.h.
