Detailed Description

template<typename T>
class nav_grid::VectorNavGrid< T >

A straight-forward implementation of the NavGrid class where the data for cell (x, y) is stored in a std::vector with index (y * info.width + x).

template<typename T>

unsigned int nav_grid::VectorNavGrid< T >::getIndex	(	unsigned int	mx,
		unsigned int	my
	)		const `[inline]`

Given two grid coordinates... compute the associated index.

Parameters:

[in]	mx	The x coordinate
[in]	my	The y coordinate

Returns:: The associated index

Definition at line 203 of file vector_nav_grid.h.

template<typename T>

unsigned int nav_grid::VectorNavGrid< T >::getIndex	(	double	x,
		double	y
	)		const `[inline]`

Given two world coordinates... compute the associated index.

Parameters:

[in]	mx	The x coordinate
[in]	my	The y coordinate

Returns:: The associated index

Definition at line 214 of file vector_nav_grid.h.

template<typename T>

T nav_grid::VectorNavGrid< T >::getValue	(	const unsigned int	x,
		const unsigned int	y
	)		const `[inline, override, virtual]`

get the value of the grid at (x,y)

Parameters:

x[in]	Valid x coordinate
y[in]	Valid y coordinate

Returns:: value at (x,y)

Implements nav_grid::NavGrid< T >.

Definition at line 176 of file vector_nav_grid.h.

template<typename T>

void nav_grid::VectorNavGrid< T >::indexToCells	(	unsigned int	index,
		unsigned int &	mx,
		unsigned int &	my
	)		const `[inline]`

Given an index... compute the associated grid coordinates.

Parameters:

[in]	index	The index
[out]	mx	Set to the associated x grid coordinate
[out]	my	Set to the associated y grid coordinate

Definition at line 227 of file vector_nav_grid.h.

template<typename T>

T nav_grid::VectorNavGrid< T >::operator[] ( unsigned int i ) const [inline]

Overloading the [] operator so that the data can be accessed directly with vector_nav_grid[i]

Definition at line 188 of file vector_nav_grid.h.

template<typename T>

T& nav_grid::VectorNavGrid< T >::operator[] ( unsigned int i ) [inline]

Definition at line 189 of file vector_nav_grid.h.

template<typename T>

void nav_grid::VectorNavGrid< T >::reset ( ) [inline, override, virtual]

Reset the contents of the grid to the default value.

Implements nav_grid::NavGrid< T >.

Definition at line 58 of file vector_nav_grid.h.

template<typename T>

void nav_grid::VectorNavGrid< T >::setInfo ( const NavGridInfo & new_info ) [inline, override, virtual]

Change the info while attempting to keep the values associated with the grid coordinates.

If the width changes, we need to move each row to its new location

If just the height changes, then we can resize the vector without having to move elements

We just overwrite the rest of the grid info

Implements nav_grid::NavGrid< T >.

Definition at line 72 of file vector_nav_grid.h.

template<typename T>

void nav_grid::VectorNavGrid< T >::setValue	(	const unsigned int	x,
		const unsigned int	y,
		const T &	value
	)		`[inline, override, virtual]`

set the value of the grid at (x,y)

Parameters:

x[in]	Valid x coordinate
y[in]	Valid y coordinate
value[in]	New Value

Implements nav_grid::NavGrid< T >.

Definition at line 171 of file vector_nav_grid.h.

template<typename T>

unsigned int nav_grid::VectorNavGrid< T >::size ( ) const [inline]

Return the size of the vector. Equivalent to width * height.

Returns:: size of the vector

Definition at line 195 of file vector_nav_grid.h.

template<typename T>

void nav_grid::VectorNavGrid< T >::updateInfo ( const NavGridInfo & new_info ) [inline, override, virtual]

Update the info while keeping the data geometrically in tact.

If the resolution or frame_id changes, reset all the data.

Otherwise, adjust the new_info so the grid stays aligned (The grid's new info will be within a resolution-length of the original new_info). Then copy the common values into the new grid.

Parameters:

[in] new_info New information to update the grid with

Reimplemented from nav_grid::NavGrid< T >.
