Detailed Description

An instance of the built-in Promise constructor (ES6 draft).

Member Enumeration Documentation

◆ PromiseState

enum v8::Promise::PromiseState

State of the promise. Each value corresponds to one of the possible values of the [[PromiseState]] field.

Enumerator
kPending 
kFulfilled 
kRejected 

Member Function Documentation

◆ Cast()

Promise * v8::Promise::Cast ( v8::Value *  value)
inlinestatic

◆ Catch() [1/2]

MaybeLocal< Promise > v8::Promise::Catch ( Local< Context >  context,
Local< Function >  handler 
)

◆ Catch() [2/2]

Local< Promise > v8::Promise::Catch ( Local< Function >  handler)

Register a resolution/rejection handler with a promise. The handler is given the respective resolution/rejection value as an argument. If the promise is already resolved/rejected, the handler is invoked at the end of turn.

◆ HasHandler()

bool v8::Promise::HasHandler ( )

Returns true if the promise has at least one derived promise, and therefore resolve/reject handlers (including default handler).

◆ Result()

Local< Value > v8::Promise::Result ( )

Returns the content of the [[PromiseResult]] field. The Promise must not be pending.

◆ State()

PromiseState v8::Promise::State ( )

Returns the value of the [[PromiseState]] field.

◆ Then() [1/2]

MaybeLocal< Promise > v8::Promise::Then ( Local< Context >  context,
Local< Function >  handler 
)

◆ Then() [2/2]

Local< Promise > v8::Promise::Then ( Local< Function >  handler)
