Detailed Description

template<class CElemType>
class CSIBCArray< CElemType >

Simple, all-purpose chunked array used by other classes.

This class is frequently used throughout the FTK and Semantic Layer. It is the desired method for using arrays.

Constructor & Destructor Documentation

CSIBCArray ( const long  in_lNbElem = 0  )  [inline]

Constructor. Allocates in_lNbElem elements of storage in the new array.

Parameters:
in_lNbElem  Initial element storage space to allocate. (Defaults to 0).

Member Function Documentation

long GetUsed (  )  const [inline]

Returns the number of element storage spaces that contain valid elements.

Returns:
long Number of used element storage spaces.
See also:
CSIBCArray::GetSize

CSIBCArray::UsedMem

long GetSize (  )  const [inline]

Returns the number of allocated element storage spaces.

Returns:
long Number of allocated element storage spaces.
See also:
CSIBCArray::GetUsed

CSIBCArray::AllocatedMem

long UsedMem (  )  const [inline]

Returns the amount memory used by element storage spaces that contain valid elements.

Returns:
long The amount of memory used by valid element storage (in bytes).
See also:
CSIBCArray::GetUsed

CSIBCArray::AllocatedMem

long AllocatedMem (  )  const [inline]

Returns the total memory allocated by element storage spaces in the array. This does not include the size of the SIBCArray object itself.

Returns:
long The amount of memory allocated by element storage spaces (in bytes).
See also:
CSIBCArray::GetSize

CSIBCArray::AllocatedMem

long Reserve ( const long  in_lNbElem  )  [inline]

Marks in_lNbElem elements as used. If there is sufficient allocated space to reserve in_lNbElem, no extra element storage is allocated. Otherwise, storage space is resized to make room for exactly in_lNbElem storage spaces.

Parameters:
in_lNbElem  Number of element storage spaces to reserve.
Returns:
long The number of elements used in the array.
See also:
CSIBCArray::Resize

CSIBCArray::Extend

CSIBCArray::InsertAt

long Resize ( const long  in_lNewNbElem  )  [inline]

Changes the number of cells used in the array to in_lNewNbElem. If there is sufficient space allocated to set in_lNewNbElem elements used, no space is allocated. Otherwise, twice the requested number of elements are allocated to the array, and in_lNewNbElem spaces are set to used. This is done so allocation occurs less frequently.

Parameters:
in_lNewNbElem  Number of elements to resize the array to.
Returns:
long Number of used elements in the resized array.
See also:
CSIBCArray::Reserve

CSIBCArray::Extend

CSIBCArray::InsertAt

long Extend ( const long  in_lNbElem  )  [inline]

Extends the number of cells used in the array by in_lNbElem elements. This is equivalent to calling SIBCArray::Resize with in_lNbElem + SIBCArray::GetUsed().

Parameters:
in_lNbElem  Number of extra elements to set to used in the array.
Returns:
long Number of used elements in the extended array.
See also:
CSIBCArray::Reserve

CSIBCArray::Resize

CSIBCArray::InsertAt

CSIBCArray::Add

long Add ( CElemType  in_Elem  )  [inline]

Adds an element to the end of the array.

Parameters:
in_Elem  Element of the template declaration type to add at the end of the array.
Returns:
long Number of used elements in the array, with the new element added.
See also:
CSIBCArray::Reserve

CSIBCArray::Resize

CSIBCArray::Extend

CSIBCArray::InsertAt

CSIBCArray::operator[]

long InsertAt ( const long  idx,
const long  nb  
) [inline]

Inserts nb element storage spaces at the array index idx.

Parameters:
idx  Index to insert element storage spaces at.
nb  Number of element storage spaces to insert.
Returns:
long Number of used elements in the array, after the insertion.
See also:
CSIBCArray::Reserve

CSIBCArray::Resize

CSIBCArray::Extend

CSIBCArray::DeleteAt

CSIBCArray::Set

void DeleteAt ( const long  idx,
const long  nb  
) [inline]

Deletes nb element storage spaces at the array index idx.

Parameters:
idx  Index to begin element deletion
nb  Number of elements to delete.
See also:
CSIBCArray::InsertAt

CSIBCArray::Set

CElemType & operator[] ( const unsigned long  in_lIndex  )  const [inline]

Indexing operator. Returns a reference to the element at the index in_lIndex.

Parameters:
in_lIndex  Index of the parameter to get.
Returns:
CElemType& Reference to the element at the index in_lIndex.
See also:
CSIBCArray::Add

CSIBCArray::Set

CElemType & operator[] ( const unsigned long  in_lIndex  )  [inline]

Indexing operator. Returns a reference to the element at the index in_lIndex.

Parameters:
in_lIndex  Index of the parameter to get.
Returns:
CElemType& Reference to the element at the index in_lIndex.
See also:
CSIBCArray::Add

CSIBCArray::Set

long Pack ( long  i_MaxWasted = 4  )  [inline]

Discards element storage spaces allocated but not used in the array, if at least i_MaxWasted elements are unused. Note: This function should only be used after major array sizing is done.

Parameters:
i_MaxWasted  Number of elements required to be wasted before packing occurs (defaults to 4).
Returns:
long Number of elements used in the array.
See also:
CSIBCArray::DisposeData

void DisposeData ( void   )  [inline]

Deletes all element storage spaces, and sets allocated and used element storage spaces both to zero.

See also:
CSIBCArray::Become

int Become ( CSIBCArray< CElemType > &  in_rSrcObject  )  [inline]

Sets this array to contain all data from the in_rSrcObject array, and then sets the in_rSrcObject to contain no elements. This destroys all data originally contained within this array.

Parameters:
in_rSrcObject  The object to take data from.
Returns:
int Always returns zero.
See also:
CSIBCArray::Copy

int Copy ( const CSIBCArray< CElemType > &  in_rSrcObject  )  [inline]

Allocates memory in which to store as many (or more) elements contained in in_rSrcObject, and copies the data from in_rSrcObject into this array. This destroy all data originally stored within this array.

Parameters:
in_rSrcObject  The array source to copy data from.
Returns:
int Returns the number of elements used.
See also:
CSIBCArray::operator=

CSIBCArray< CElemType > & operator= ( const CSIBCArray< CElemType > &  in_rSrcObject  )  [inline]

Sets this array to contain the same information as in_rSrcObject. The functionality is equivalent to SIBCArray::Copy.

Parameters:
in_rSrcObject  Array object to copy data from.
Returns:
SIBCArray<CElemType>& Reference to this array.
See also:
CSIBCArray::Copy

CElemType* ArrayPtr ( void   )  [inline]

Returns the array used internally by this object.

Returns:
CElemType* Pointer to the first element in the internal array used by this object.

CElemType* * ArrayPtrPtr ( void   )  [inline]

Returns a pointer to the array used internally by this object.

Returns:
CElemType** Pointer to a pointer to the first element in the internal array used by this object.

void Set ( long  start,
long  nb,
CElemType  value  
) [inline]

Sets a given number of elements, nb, starting at index start to the element given by value.

Parameters:
start  The index to start the modification of elements.
nb  Number of elements to set the value of.
value  The value to set the elements to.
