Instance Method

enumerateChildObjects(of:root:using:stopPointer:)

Executes the specified block using each object in this object's child hierarchy.

Declaration

func enumerateChildObjects(of objectClass: AnyClass, root: MDLObject, using block: @escaping (MDLObject, UnsafeMutablePointer<ObjCBool>) -> Void, stopPointer: UnsafeMutablePointer<ObjCBool>)

Parameters

objectClass

A Model I/O class representing a type of child objects to evaluate. For example, pass the MDLMesh class to evaluate all 3D objects stored in the asset. Pass the MDLObject class to evaluate all child objects regardless of type.

root

The root object at which to begin traversing the child object hierarchy.

block

The block to apply to child objects. This block takes two parameters: the object to be evaluated by the block, and a stop pointer that you can set to true to stop further evaluation of the object hierarchy.

stopPointer

Set this pointer's value to true during enumeration to stop further enumeration of the object hierarchy.
