Constructor & Destructor Documentation

SnapshotCreator ( intptr_t *  external_references = nullptr,
StartupData existing_blob = nullptr 
)

Create and enter an isolate, and set it up for serialization. The isolate is either created from scratch or from an existing snapshot. The caller keeps ownership of the argument snapshot.

Parameters
existing_blobexisting snapshot from which to create this one.
external_referencesa null-terminated array of external references that must be equivalent to CreateParams::external_references.
SnapshotCreator ( const SnapshotCreator )
delete

Member Function Documentation

size_t AddContext ( Local< Context context)

Add a context to be included in the snapshot blob.

Returns
the index of the context in the snapshot blob.
size_t AddTemplate ( Local< Template template_obj)

Add a template to be included in the snapshot blob.

Returns
the index of the template in the snapshot blob.
StartupData CreateBlob ( FunctionCodeHandling  function_code_handling)

Created a snapshot data blob. This must not be called from within a handle scope.

Parameters
function_code_handlingwhether to include compiled function code in the snapshot.
Returns
{ nullptr, 0 } on failure, and a startup snapshot on success. The caller acquires ownership of the data array in the return value.
Isolate* GetIsolate ( )
Returns
the isolate prepared by the snapshot creator.
void operator= ( const SnapshotCreator )
