Detailed Description

template<typename T>
class System::Collections::Generic::Queue< T >

Queue class forward declaration.

Queue container wrapping STL list. Objects of this class should only be allocated using System::MakeObject() function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into System::SmartPtr pointer and use this pointer to pass it to functions as argument.

Template Parameters
TElement type.

Member Function Documentation

◆ Clear()

template<typename T >
virtual void System::Collections::Generic::Queue< T >::Clear ( )
inlinevirtual

Deletes all elements in queue.

◆ Contains()

template<typename T >
virtual bool System::Collections::Generic::Queue< T >::Contains ( const T &  item) const
inlinevirtual

Checks if queue contains specific element using operator == to compare elements.

Parameters
itemItem to look for.
Returns
True if item is present, false otherwise.

◆ data() [1/2]

template<typename T >
queue_t& System::Collections::Generic::Queue< T >::data ( )
inline

Underlying data structure accessor.

Returns
Reference to underlying data structure.

◆ data() [2/2]

template<typename T >
const queue_t& System::Collections::Generic::Queue< T >::data ( ) const
inline

Underlying data structure accessor.

Returns
Const reference to underlying data structure.

◆ Dequeue()

template<typename T >
T System::Collections::Generic::Queue< T >::Dequeue ( )
inline

Gets item from the beginning of the queue.

Returns
Popped item.

◆ Enqueue()

template<typename T >
void System::Collections::Generic::Queue< T >::Enqueue ( const T &  item)
inline

Puts item to the end of the queue.

Parameters
itemItem to push.

◆ get_Count()

template<typename T >
virtual int System::Collections::Generic::Queue< T >::get_Count ( ) const
inlinevirtual

Gets number of elements in queue.

Returns
Actual number of elements.

◆ GetEnumerator()

template<typename T >
IEnumeratorPtr System::Collections::Generic::Queue< T >::GetEnumerator ( )
inlineoverridevirtual

Gets enumerator to iterate through the queue.

Returns
Pointer to newly created enumerator.

Implements System::Collections::Generic::IEnumerable< T >.

◆ Peek()

template<typename T >
T System::Collections::Generic::Queue< T >::Peek ( )
inline

Gets item from the beginning of the queue, but does not remove it from queue.

Returns
First item in queue.

◆ SetTemplateWeakPtr()

template<typename T >
void System::Collections::Generic::Queue< T >::SetTemplateWeakPtr ( unsigned int  argument)
inlineoverridevirtual

Makes queue treat stored pointers as weak (if applicable).

Parameters
argumentShould be 0 as there is only one template argument present.

Reimplemented from System::Object.
