Member Function Documentation

Evaluate()

V8_WARN_UNUSED_RESULT MaybeLocal<Value> Evaluate

(

Local< Context >

context

)

ModuleEvaluation

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()

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

ModuleDeclarationInstantiation

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