Public Types
typedef T	DataType
	The stored data type.
typedef T *	iterator

Public Member Functions
	GmSingleVector ()
	Default constructor.
	GmSingleVector (size_t nvalues)
	The constructor initializing the vector with the given size. The vector contents is NOT initialized.
bool	isDual () const
	Returns false, since this is NOT a Dual vector.
size_t	size () const
	Returns the vector size.
const T *	iptr (size_t index) const
	Returns a pointer to the index data inside the vector.
T *	iptr (size_t index)
	Non-const overload for iptr()
const T &	operator[] (size_t index) const
	Standard indexing operator.
T &	operator[] (size_t index)
	Non-const overload for the standard indexing operator.
iterator	begin ()
iterator	end ()
bool	addValues (size_t numAddedValues, bool tight=false)
	Adds numAddedValues to the set, without any initialization. Returns true on success, false on error. On errors previous values are kept. If the vector is empty, the allocated size will be adjusted to exactly the given size. Otherwise, a growing factor of half of the previous size will be used, unless that is insufficient. If tight is set to true, the allocated size will always match the needed size (unless already allocated).
void	restoreSize (size_t oldNumValues)
	Restores the size of the set to the previous size before the last call to addValues(). Can be called with the current size if addValues was not called.
void	removeValues (size_t index, size_t numValues)
	Removes numValues from the set, starting from (and including) index.
void	clear ()
	Clears all stored data returning the object to a default constructed state.
void	zero (size_t index=0)
	Clears the vector area by setting to zero all entries starting at the given index.
size_t	usedMemory () const
	Returns an estimative of the memory used by the data set in bytes.
int	numDumpBuffers () const
	Returns the number of internal buffers used by this implementation.
char *	dumpBuffer (int i) const
	Returns the i'th internal buffer, i from 0 to numDumpBuffers()-1.
size_t	dumpBufferSize (int i) const
	Returns the size in bytes of the i'th internal buffer returned by dumpBuffer(i)

Private Attributes

	The real vector.

Detailed Description

template<class T>
class GmSingleVector< T >

A class with the same API as GmDualVector storing a single vector. No query "if" overhead. Ideal for static meshes.

Accepts only POD types. In fact, its implementation is mostly a wrapper calling GmPODVector methods, adapting its interface to the GmDualVector interface. The compiler should be able to inline all the calls with no overhead!

Member Function Documentation

usedMemory()

template<class T >

size_t GmSingleVector< T >::usedMemory ( ) const

inline

Returns an estimative of the memory used by the data set in bytes.

  It returns in general the variable memory that depends on the number of set
  entries but does not include constant overheads used by the class for control
