Field Documentation

AddHistogramSampleCallback add_histogram_sample_callback

Definition at line 6290 of file v8.h.

ArrayBuffer::Allocator* array_buffer_allocator

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

Definition at line 6296 of file v8.h.

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.

Definition at line 6264 of file v8.h.

ResourceConstraints constraints

ResourceConstraints to use for the new Isolate.

Definition at line 6269 of file v8.h.

CounterLookupCallback counter_lookup_callback

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

Definition at line 6281 of file v8.h.

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.

Definition at line 6289 of file v8.h.

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. Furthermore, if an entry_hook is given, V8 will not use a snapshot, including custom snapshots.

Definition at line 6258 of file v8.h.

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.

Definition at line 6304 of file v8.h.

StartupData* snapshot_blob

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