| enum Status |
|
static |
Creates a new SyntheticModule with the specified export names, where evaluation_steps will be executed upon module evaluation. export_names must not contain duplicates. module_name is used solely for logging/debugging and doesn't affect module behavior.
| V8_WARN_UNUSED_RESULT MaybeLocal<Value> Evaluate | ( | Local< Context > | context | ) |
Evaluates the module and its dependencies.
If status is kInstantiated, run the module's code. On success, set status to kEvaluated and return the completion value; on failure, set status to kErrored and propagate the thrown exception (which is then also available via |GetException|).
For a module in kErrored status, this returns the corresponding exception.
| int GetIdentityHash | ( | ) | const |
Returns the identity hash for this object.
Returns the namespace object of this module.
The module's status must be at least kInstantiated.
| Local<FixedArray> GetModuleRequests | ( | ) | const |
Returns the ModuleRequests for this module.
| Status GetStatus | ( | ) | const |
Returns the module's current status.
| Local<UnboundModuleScript> GetUnboundModuleScript | ( | ) |
Returns the corresponding context-unbound module script.
The module must be unevaluated, i.e. its status must not be kEvaluating, kEvaluated or kErrored.
| V8_WARN_UNUSED_RESULT Maybe<bool> InstantiateModule | ( | Local< Context > | context, |
| ResolveModuleCallback | callback | ||
| ) |
| bool IsGraphAsync | ( | ) | const |
Returns whether this module or any of its requested modules is async, i.e. contains top-level await.
The module's status must be at least kInstantiated.
| bool IsSourceTextModule | ( | ) | const |
Returns whether the module is a SourceTextModule.
| bool IsSyntheticModule | ( | ) | const |
Returns whether the module is a SyntheticModule.
| int ScriptId | ( | ) |
Returns the underlying script's id.
The module must be a SourceTextModule and must not have a kErrored status.
| V8_WARN_UNUSED_RESULT Maybe<bool> SetSyntheticModuleExport | ( | Isolate * | isolate, |
| Local< String > | export_name, | ||
| Local< Value > | export_value | ||
| ) |
Set this module's exported value for the name export_name to the specified export_value. This method must be called only on Modules created via CreateSyntheticModule. An error will be thrown if export_name is not one of the export_names that were passed in that CreateSyntheticModule call. Returns Just(true) on success, Nothing<bool>() if an error was thrown.
| Location SourceOffsetToLocation | ( | int | offset | ) | const |
For the given source text offset in this module, returns the corresponding Location with line and column numbers.
| V8_DEPRECATE_SOON | ( | "Use Module::GetModuleRequests() and FixedArray::Length()." | ) | const |
Returns the number of modules requested by this module.
| V8_DEPRECATE_SOON | ( | "Use Module::GetModuleRequests() and ModuleRequest::GetSpecifier()." | ) | const |
Returns the ith module specifier in this module. i must be < GetModuleRequestsLength() and >= 0.
| V8_DEPRECATE_SOON | ( | "Use | Module::GetModuleRequests(), |
| ModuleRequest::GetSourceOffset() | , | ||
| and " "Module::SourceOffsetToLocation()." | |||
| ) | const |
Returns the source location (line number and column number) of the ith module specifier's first occurrence in this module.
| V8_DEPRECATE_SOON | ( | "Use the version of InstantiateModule that takes a ResolveModuleCallback " "parameter" | ) |
Instantiates the module and its dependencies.
Returns an empty Maybe<bool> if an exception occurred during instantiation. (In the case where the callback throws an exception, that exception is propagated.)
| V8_DEPRECATED | ( | "Use the preceding SetSyntheticModuleExport with an Isolate | parameter, |
| " "instead of the one that follows. The former will throw a runtime " "error if called for an export that doesn 't exist(as per spec);" "the latter will crash with a failed CHECK()." | |||
| ) |
