// nsIStringEnumerator/nsIUTF8StringEnumerator implementations
//
// Currently all implementations support both interfaces. The
// constructors below provide the most common interface for the given
// type (i.e. nsIStringEnumerator for char16_t* strings, and so
// forth) but any resulting enumerators can be queried to the other
// type. Internally, the enumerators will hold onto the type that was
// passed in and do conversion if GetNext() for the other type of
// string is called.
// There are a few different types of enumerators:
//
// These enumerators hold a pointer to the array. Be careful
// because modifying the array may confuse the iterator, especially if
// you insert or remove elements in the middle of the array.
//
// The non-adopting enumerator requires that the array sticks around
// at least as long as the enumerator does. These are for constant
// string arrays that the enumerator does not own, this could be used
// in VERY specialized cases such as when the provider KNOWS that the
// string enumerator will be consumed immediately, or will at least
// outlast the array.
// For example:
//
// nsTArray<nsCString> array;
// array.AppendCString("abc");
// array.AppendCString("def");
// NS_NewStringEnumerator(&enumerator, &array, true);
//
// // call some internal method which iterates the enumerator
// InternalMethod(enumerator);
// NS_RELEASE(enumerator);
//

NS_NewStringEnumerator(nsIStringEnumerator** aResult,
const nsTArray<nsString>* aArray);
// Adopting string enumerators assume ownership of the array and will
// call |operator delete| on the array when the enumerator is destroyed
// this is useful when the provider creates an array solely for the
// purpose of creating the enumerator.
// For example:
//
// nsTArray<nsCString>* array = new nsTArray<nsCString>;
// array->AppendString("abcd");
// NS_NewAdoptingStringEnumerator(&result, array);

nsresult
NS_NewAdoptingUTF8StringEnumerator(nsIUTF8StringEnumerator** aResult,

// these versions take a refcounted "owner" which will be addreffed
// when the enumerator is created, and destroyed when the enumerator
// is released. This allows providers to give non-owning pointers to
// ns*StringArray member variables without worrying about lifetime
// issues
// For example:
//
// nsresult MyClass::Enumerate(nsIUTF8StringEnumerator** aResult) {
// mCategoryList->AppendString("abcd");
// return NS_NewStringEnumerator(aResult, mCategoryList, this);
// }
