Constructor & Destructor Documentation

◆ SnapshotCreator() [1/2]

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_blob	existing snapshot from which to create this one.
external_references	a null-terminated array of external references that must be equivalent to CreateParams::external_references.

◆ ~SnapshotCreator()

~SnapshotCreator ( )

◆ SnapshotCreator() [2/2]

SnapshotCreator ( const SnapshotCreator & )

delete

Member Function Documentation

◆ AddContext()

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.

◆ AddTemplate()

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.

◆ CreateBlob()

StartupData CreateBlob ( FunctionCodeHandling function_code_handling )

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

Parameters

function_code_handling whether 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.

◆ GetIsolate()

Isolate* GetIsolate ( )

Returns: the isolate prepared by the snapshot creator.

◆ operator=()

void operator= ( const SnapshotCreator & )
