Detailed Description

template<class T>
class Radiant::GridMemT< T >

Grid (aka 2D array) base class with memory management.

Template Parameters

T	Type of objects to store

Constructor & Destructor Documentation

template<class T >

Radiant::GridMemT< T >::GridMemT ( unsigned  w = 0, unsigned  h = 0  )

inline

Constructs a new grid with the given size.

Parameters

w	The width of the grid
h	The height of the grid

template<class T >

Radiant::GridMemT< T >::GridMemT ( void *  data, unsigned  w, unsigned  h  )

inline

Constructs a new grid with the given size.

Parameters

data	pointer to grid data
w	The width of the grid
h	The height of the grid

template<class T >

Radiant::GridMemT< T >::GridMemT ( const GridMemT< T > &  that )

inline

Constructs a copy.

Parameters

that	Grid memory to copy

Member Function Documentation

template<class T >

void Radiant::GridMemT< T >::clear ( void  )

inline

Frees up the memory, and sets the width and height of this object to zero.

template<class T >

void Radiant::GridMemT< T >::copy ( const T *  src, unsigned  w, unsigned  h  )

inline

Copies data from memory.

Parameters

src	Source image data
w	Width of source image
h	Height of source image

template<class T >

GridMemT& Radiant::GridMemT< T >::operator= ( const GridMemT< T > &  that )

inline

Copies a grid.

Parameters

that	Source grid

Returns

Reference to self

template<class T >

void Radiant::GridMemT< T >::resize ( unsigned  w, unsigned  h  )

inline

Resizes this grid, by allocating new memory as necessary Any old data will be lost in this function call.

If the number of elements in the grid stays the same, then only the dimensions of the grid are updated, but not the contents.

Parameters

w	The new width of the grid
h	The new height of the grid

template<class T >

void Radiant::GridMemT< T >::resize ( Nimble::Vector2i  size )

inline

Resizes the grid.

Parameters

size	New size of the grid
