Detailed Description

The delegate is used in Isolate::MeasureMemory API.

It specifies the contexts that need to be measured and gets called when the measurement is completed to report the results.

Both MeasurementComplete() callbacks will be invoked on completion. Each implementation of this class should hence implement only one of them, and leave the other empty.

Member Function Documentation

Default()

std::unique_ptr< MeasureMemoryDelegate > v8::MeasureMemoryDelegate::Default ( Isolate * isolate, Local< Context > context, Local< Promise::Resolver > promise_resolver, MeasureMemoryMode mode )

static

Returns a default delegate that resolves the given promise when the memory measurement completes.

Parameters

isolate	the current isolate
context	the current context
promise_resolver	the promise resolver that is given the result of the memory measurement.
mode	the detail level of the result.
