enum Status |
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.
Returns the ith module specifier in this module. i must be < GetModuleRequestsLength() and >= 0.
Location GetModuleRequestLocation | ( | int | i | ) | const |
Returns the source location (line number and column number) of the ith module specifier's first occurrence in this module.
int GetModuleRequestsLength | ( | ) | const |
Returns the number of modules requested by 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, |
ResolveCallback | callback | ||
) |
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.)
