Detailed Description

template<class ClassType>
class Jerryscript::ContextList< ClassType >

Manages a list of contexts.

Member Typedef Documentation

Callback

template<class ClassType >

using Jerryscript::ContextList< ClassType >::Callback = Delegate<void(ClassType& ctx)>

Member Function Documentation

foreach()

template<class ClassType >

void Jerryscript::ContextList< ClassType >::foreach ( Callback  callback )

inline

Invoke callback once for each context via task queue.

When calling into contexts we can do this:

JS::ContextList<MyContext> contexts;
...
String str = F("Some text");
int value = 12;
for(auto& ctx: contexts) {
  ctx.customNotify(str, value);
}

However, with many containers system responsiveness may be adversely affected. Instead, separate the calls out like this:

contexts.foreach([=](auto& ctx){
  ctx.customNotify(str, value);
});

Note that all parameters are captured by copy (using [=]) as, for example, str will be destroyed when it goes out of scope.
