impeller::ReactorGLES::Worker Class Referenceabstract

A delegate implemented by a thread on which an OpenGL context is current. There may be multiple workers for the reactor to perform reactions on. In that case, it is the workers responsibility to ensure that all of them use either the same OpenGL context or multiple OpenGL contexts in the same sharegroup. More...

## Detailed Description

## Member Function Documentation

## ◆ CanReactorReactOnCurrentThreadNow()

virtual bool impeller::ReactorGLES::Worker::CanReactorReactOnCurrentThreadNow | ( | const ReactorGLES & | reactor | ) | const
| pure virtual

Determines the ability of the worker to service a reaction on the current thread. The OpenGL context must be current on the thread if the worker says it is able to service a reaction.

Parameters

  [in] | reactor | The reactor

Returns
  If the worker is able to service a reaction. The reactor assumes the context is already current if true.

Implemented in impeller::interop::ReactorWorkerGLES, impeller::testing::MockWorker, impeller::testing::MockWorker, and impeller::PlaygroundImplGLES::ReactorWorker.
