Member Function Documentation

◆ Evaluate()

V8_WARN_UNUSED_RESULT MaybeLocal<Value> Evaluate ( Local< Context context)


Returns the completion value. TODO(neis): Be more precise or say nothing.

◆ GetException()

Local<Value> GetException ( ) const

For a module in kErrored status, this returns the corresponding exception.

◆ GetIdentityHash()

int GetIdentityHash ( ) const

Returns the identity hash for this object.

◆ GetModuleNamespace()

Local<Value> GetModuleNamespace ( )

Returns the namespace object of this module. The module's status must be kEvaluated.

◆ GetModuleRequest()

Local<String> GetModuleRequest ( int  i) const

Returns the ith module specifier in this module. i must be < GetModuleRequestsLength() and >= 0.

◆ GetModuleRequestLocation()

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.

◆ GetModuleRequestsLength()

int GetModuleRequestsLength ( ) const

Returns the number of modules requested by this module.

◆ GetStatus()

Status GetStatus ( ) const

Returns the module's current status.

◆ InstantiateModule()

V8_WARN_UNUSED_RESULT Maybe<bool> InstantiateModule ( Local< Context context,
ResolveCallback  callback 


V8_DEPRECATED ( "Use Maybe<bool> version"  ,
bool   InstantiateLocal< Context > context, ResolveCallback callback 


Returns an empty Maybe<bool> if an exception occurred during instantiation. (In the case where the callback throws an exception, that exception is propagated.)
