wxNode< T > Class Template Reference

Detailed Description

template<typename T>
class wxNode< T >

wxNode<T> is the node structure used in linked lists (see wxList) and derived classes.

You should never use wxNode<T> class directly, however, because it works with untyped (void *) data and this is unsafe. Use wxNode<T>-derived classes which are automatically defined by WX_DECLARE_LIST and WX_DEFINE_LIST macros instead as described in wxList documentation (see example there).

Also note that although there is a class called wxNode, it is defined for backwards compatibility only and usage of this class is strongly deprecated.

In the documentation below, the type T should be thought of as a "template" parameter: this is the type of data stored in the linked list or, in other words, the first argument of WX_DECLARE_LIST macro. Also, wxNode is written as wxNodeT even though it isn't really a template class -- but it helps to think of it as if it were.

Template Parameters:

T	The type stored in the wxNode.

Library:  wxBase

Public Member Functions
T *	GetData () const
	Retrieves the client data pointer associated with the node.
wxNode< T > *	GetNext () const
	Retrieves the next node or NULL if this node is the last one.
wxNode< T > *	GetPrevious ()
	Retrieves the previous node or NULL if this node is the first one in the list.
int	IndexOf ()
	Returns the zero-based index of this node within the list.
void	SetData (T *data)
	Sets the data associated with the node (usually the pointer will have been set when the node was created).

Member Function Documentation

template<typename T >

T* wxNode< T >::GetData

(

)

const

Retrieves the client data pointer associated with the node.

template<typename T >

wxNode<T>* wxNode< T >::GetNext

(

)

const

Retrieves the next node or NULL if this node is the last one.

template<typename T >

wxNode<T>* wxNode< T >::GetPrevious

(

)

Retrieves the previous node or NULL if this node is the first one in the list.

template<typename T >

int wxNode< T >::IndexOf

(

)

Returns the zero-based index of this node within the list.

The return value will be wxNOT_FOUND if the node has not been added to a list yet.

template<typename T >

void wxNode< T >::SetData

(

T *

data

)

Sets the data associated with the node (usually the pointer will have been set when the node was created).
