// This is a test for the handling of multi-dimensional Arrays in MetaspaceClosure.

//
|
|
// We choose FieldAnnotations because they happen to be implemented as a multi-dimension
|
|
// Array (Annotations::_fields_annotations, which is of type Array<Array<unsigned char>*>*,
|
|
// and is handled by the template class PointerArrayRef<T> in metaspaceClosure.hpp).
|
|
//
|
|
// Specifically, we are testing the following C code, where _fields_annotations is non-NULL:
|
|
//
|
|
// void Annotations::metaspace_pointers_do(MetaspaceClosure* it) {
|
|
// ...
|
|
// it->push(&_fields_annotations);
|

|

// which will be matched with the function
|

//
|
|
// template <typename T> void MetaspaceClosure::push(Array<T*>** mpp, Writability w = _default)
