GmPODVector< T, ControlSize, Grow > Class Template Reference

A simple vector for Plain Old Data (POD) types with the control size variable type parameterized to allow for a smaller class size with ControlSize = unsigned int, with smaller vector size limits, or for a bigger class with ControlSize = size_t. Also receives as parameter the default gorwing strategy applied by its resize procedure. More...

Public Types
typedef T	DataType
	The stored data type.

Public Member Functions
	GmPODVector ()
	Default constructor. Creates an empty vector.
	GmPODVector (ControlSize nvalues)
	The constructor initializing the vector with the given size. The vector contents is NOT initialized.
	~GmPODVector ()
	Destructor.
ControlSize	size () const
	Returns the vector size.
ControlSize	capacity () const
	Returns the vector allocated capacity.
const T *	data () const
	Returns a pointer to the data inside the vector.
T *	data ()
	Non-const overload for data()
const T &	operator[] (ControlSize index) const
	Standard indexing operator.
T &	operator[] (ControlSize index)
	Non-const overload for the standard indexing operator.
bool	append (const T &v)
	Appends v to the vector end, growing the vector, if needed, using the growth algorithm specified as the Grow template parameter. Returns true on success, false on error.
void	remove (ControlSize index, ControlSize numValues)
	Removes numValues entries from the vector starting at index.
bool	resize (ControlSize newSize, GmPODGrowT grow=Grow)
	Resizes the vector to the given size using the speciefied grow policy. More...
void	shrink ()
	Shriks the allocated size to match the vector size if possible. Never fails but might do nothing.
void	clear ()
	Clears the vector deallocating used memory.

Detailed Description

template<class T, class ControlSize = size_t, GmPODGrowT Grow = GmPODVectorStdGrow<ControlSize>>
class GmPODVector< T, ControlSize, Grow >

A simple vector for Plain Old Data (POD) types with the control size variable type parameterized to allow for a smaller class size with ControlSize = unsigned int, with smaller vector size limits, or for a bigger class with ControlSize = size_t. Also receives as parameter the default gorwing strategy applied by its resize procedure.

Member Function Documentation

resize()

template<class T, class ControlSize = size_t, GmPODGrowT Grow = GmPODVectorStdGrow<ControlSize>>

bool GmPODVector< T, ControlSize, Grow >::resize ( ControlSize  newSize, GmPODGrowT  grow = Grow  )

inline

Resizes the vector to the given size using the speciefied grow policy.

If newSize is bigger than the current allocated size, the vector will be grown using the policy. New entries are NOT initialized. If new size is smaller than the current size, space will be removed from the vector end. The allocated space never shrinks, and so reducing the size never fails. You can explicitely reduce the allocated size by calling shrink().
