JSObjectGetPropertyNamesCallback typedef

JSObjectGetPropertyNamesCallback = Void Function(JSContextRef ctx, JSObjectRef object, JSPropertyNameAccumulatorRef propertyNames)

The callback invoked when collecting the names of an object's properties. ctx The execution context to use. object The JSObject whose property names are being collected. propertyNames A JavaScript property name accumulator in which to accumulate the names of object's properties. @discussion If you named your function GetPropertyNames, you would declare it like this:

void GetPropertyNames(JSContextRef ctx, JSObjectRef object, JSPropertyNameAccumulatorRef propertyNames);

Property name accumulators are used by JSObjectCopyPropertyNames and JavaScript for...in loops.

Use JSPropertyNameAccumulatorAddName to add property names to accumulator. A class's getPropertyNames callback only needs to provide the names of properties that the class vends through a custom getProperty or setProperty callback. Other properties, including statically declared properties, properties vended by other classes, and properties belonging to object's prototype, are added independently.

typedef void (*JSObjectGetPropertyNamesCallback) (JSContextRef ctx, JSObjectRef object, JSPropertyNameAccumulatorRef propertyNames);
