CArrayFixBase Class Reference

class CArrayFixBase : public CBase

Base class for arrays of fixed length objects.

It provides implementation and public functions which are common to all arrays of this type.

The class is always derived from and is never instantiated explicitly.

CArrayFixBase(TBufRep, TInt, TInt)

IMPORT_C	CArrayFixBase	(	TBufRep	aRep,
			TInt	aRecordLength,
			TInt	aGranularity
		)	[protected]

Parameters

TBufRep aRep
TInt aRecordLength

~CArrayFixBase()

IMPORT_C

~CArrayFixBase

(

)

Destructor.

This frees all resources owned by the object, prior to its destruction.

Member Functions Documentation

At(TInt)

IMPORT_C TAny *

(

TInt

anIndex

)

const

Parameters

TInt anIndex

AtR(const CBase *, TInt)

IMPORT_C const TAny *	AtR	(	const CBase *	aPtr,
			TInt	anIndex
		)	[protected, static]

Parameters

const CBase * aPtr
TInt anIndex

Back(TInt)

IMPORT_C TAny *

Back

(

TInt

anIndex

)

const

Parameters

TInt anIndex

Compress()

IMPORT_C void

Compress

(

)

Compresses the array.

The function removes the excess space from the array buffer. The effect is to reduce the memory allocated to the array buffer so that it is just sufficient to contain the elements of the array. This applies to both flat and segmented array buffers.

If the array is empty, then the memory allocated to the array buffer is freed.

Count()

TInt

Count

(

)

const [inline]

Gets the number of elements held in the array.

CountR(const CBase *)

IMPORT_C TInt

CountR

(

const CBase *

aPtr

)

[protected, static]

Parameters

const CBase * aPtr

Delete(TInt)

IMPORT_C void

Delete

(

TInt

anIndex

)

Deletes a single element from the array at a specified position.

Deleting elements from the array does not cause the array buffer to be automatically compressed. Call CArrayFixBase::Compress() to return excess space to the heap.

panic: E32USER-CBase 21, if anIndex is negative or is greater than or equal to the number of elements currently in the array.

CArrayFixBase::Compress

Parameters

TInt anIndex

The position within the array at which to delete the element, This is a value relative to zero.

Delete(TInt, TInt)

IMPORT_C void	Delete	(	TInt	anIndex,
			TInt	aCount
		)

Deletes one or more contiguous elements from the array, starting at a specific position.

Deleting elements from the array does not cause the array buffer to be automatically compressed. Call CArrayFixBase::Compress() to return excess space to the heap.

panic: E32USER-CBase 21, if anIndex is negative, or is greater than or equal to the number of elements currently in the array.

panic: E32USER-CBase 22, if aCount is negative.

panic: E32USER-CBase 29, if the sum of anIndex and aCount is greater than or equal to the number of elements currently in the array.

Parameters

TInt anIndex	The position within the array from where deletion of elements is to start. The position is relative to zero, i.e. zero implies that elements, starting with the first, are deleted from the array.
TInt aCount	The number of contiguous elements to be deleted from the array.
