index or -1 if this container does not contain the element.

public: virtual bool isConstructed() const;

Tests if this object has been constructed.

Returns:
true if object has been constructed successfully.

public: virtual bool isEmpty() const;

Tests if this collection has elements.

Returns:
true if this collection does not contain any elements.

public: virtual bool isIllegal(const Type& value) const;

Tests if given value is an illegal.

Parameters:
value — testing value.
true — if value is an illegal.

public: virtual bool isIndex(int32 index) const;

Tests if given index is available.

Parameters:
index — checking position in this container.

Returns:
true if index is present.

public: static bool isObject(const Type* obj);

Tests if given object has been constructed object.

Parameters:
obj — pointer to object.

Returns:
true if object has been constructed successfully.

public: virtual ::api::Iterator<Type>* iterator();

Returns an iterator of elements.

You have to call delete operator for returned iterator after it is used.

Returns:
pointer to new iterator.

Returns a number of elements in this container.

Returns:
number of elements.

public: virtual ::api::ListIterator<Type>* listIterator(int32 index);

Returns a list iterator of this container elements.

You have to call delete operator for returned iterator after it is used. Given index must not be out of bounds (index < 0 || index > length()).

Parameters:
index — start position in this container.

Returns:
pointer to new list iterator.

public: void operator delete(void* ptr);

Operator delete.

Parameters:
ptr — address of allocated memory block or a null pointer.

public: void* operator new(size_t size);

Operator new.

Parameters:
size — number of bytes to allocate.

Returns:
allocated memory address or a null pointer.

public: void* operator new(size_t size, void* ptr);

Operator new.

Parameters:
size — unused.
ptr — pointer to reserved memory area

Returns:
given pointer.
