Constructor & Destructor Documentation

Array2D()

template<typename T >

tbq::Array2D< T >::Array2D ( size_t nbRows, size_t nbCols )

explicit

Construct a 2D array at specified size.

Parameters

[in]	nbRows	Number of rows.
[in]	nbCols	Number of colums

getRows()

template<typename T >

size_t tbq::Array2D< T >::getRows

(

)

const

Get number of rows.

Returns

Returns number of rows available

clear()

template<typename T >

void tbq::Array2D< T >::clear

(

)

Clear content of 2D array.

Size will be reset to 0 and all elements will be removed

Note

This method doesn't impact internal capacity of the array, see resize() method for more details.

resize()

resize()

template<typename T >

void tbq::Array2D< T >::resize	(	size_t	nbRows,
		size_t	nbCols )

Resize array to specified size.

Parameters

[in]	nbRows	Number of rows.
[in]	nbCols	Number of colums

Note

This method will only extend capacity of the 2D array, no shrink operation will be performed.

insert()

template<typename T >

void tbq::Array2D< T >::insert	(	size_t	row,
		size_t	col,
		const T &	value )

Use to insert a value at specified indexes.

Parameters

[in]	row	Row index to use. Must be valid (i.e 0 <= row < getRows()).
[in]	col	Column index to use. Must be valid (i.e 0 <= col < getCols()).
[in]	value	Value to insert

operator()() [1/2]

template<typename T >

T & tbq::Array2D< T >::operator()	(	size_t	row,
		size_t	col )

Get modifiable reference to an element.

Parameters

[in]	row	Row index to use. Must be valid (i.e 0 <= row < getRows()).
[in]	col	Column index to use. Must be valid (i.e 0 <= col < getCols()).

Returns

Returns modifiable reference to an element

operator()() [2/2]

template<typename T >

const T & tbq::Array2D< T >::operator()	(	size_t	row,
		size_t	col ) const

Get constant reference to an element.

Parameters

[in]	row	Row index to use. Must be valid (i.e 0 <= row < getRows()).
[in]	col	Column index to use. Must be valid (i.e 0 <= col < getCols()).

Returns

Returns constant reference to an element
