allow_atomics_wait

bool allow_atomics_wait

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

array_buffer_allocator

ArrayBuffer::Allocator* array_buffer_allocator

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

code_event_handler

JitCodeEventHandler code_event_handler

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

constraints

ResourceConstraints constraints

ResourceConstraints to use for the new Isolate.

Definition at line 7222 of file v8.h.

counter_lookup_callback

CounterLookupCallback counter_lookup_callback

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

Definition at line 7234 of file v8.h.

Referenced by Isolate::CreateParams::CreateParams().

create_histogram_callback

CreateHistogramCallback create_histogram_callback

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.

entry_hook

FunctionEntryHook entry_hook

The optional entry_hook allows the host application to provide the address of a function that's invoked on entry to every V8-generated function. Note that entry_hook is invoked at the very start of each generated function. An entry_hook can only be provided in no-snapshot builds; in snapshot builds it must be nullptr.

external_references

const intptr_t* external_references

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.

only_terminate_in_safe_scope

bool only_terminate_in_safe_scope

Termination is postponed when there is no active SafeForTerminationScope.

Definition at line 7268 of file v8.h.

snapshot_blob

StartupData* snapshot_blob

Explicitly specify a startup snapshot blob. The embedder owns the blob.
