collectDescendantsOfTypeTo¶

inline fun <reified T : PsiElement, C : MutableCollection<T>> PsiElement.collectDescendantsOfTypeTo(
    to: C, 
    crossinline canGoInside: (PsiElement) -> Boolean, 
    noinline predicate: (T) -> Boolean = { true }
): C

Adds this element and all descendants of type T satisfying predicate to to in post-order. canGoInside controls traversal into children but does not prevent the current element from being added.
