Detailed Description

template<typename T>
class mds::base::CPartedData< T >

Class template managing references to a block of memory that is allocated in parts as a sequence of smaller memory blocks.

Functions malloc() and free() are used internally.
Provides own data reference counting mechanism.

Constructor & Destructor Documentation

template<typename T >

CPartedData::CPartedData ( )

Default constructor allocates data of zero length.

template<typename T >

CPartedData::CPartedData ( EEmptyConst ) [explicit]

This constructor does no allocation of the data.

Be sure that one of the methods create(...) is called somewhere.
Use with care!

template<typename T >

CPartedData::CPartedData ( tSize Size ) [explicit]

Constructor that allocates a given size of data.

Data of the zero size can be allocated.

template<typename T >

CPartedData::CPartedData	(	tConstDataPtr	pData,
		tSize	Size
	)

Constructor that copies a specified data.

template<typename T >

mds::base::CPartedData< T >::CPartedData ( const CPartedData< T > & Data )

Constructor copies a given data.

template<typename T >

mds::base::CPartedData< T >::CPartedData	(	const CPartedData< T > &	Data,
		EMakeRef
	)

Constructor which makes reference to an existing data.

Usage: CPartedData(Data, REFERENCE).

template<typename T >

CPartedData::~CPartedData ( )

Destructor deallocates the data if the number of references decreases to zero.

Member Function Documentation

template<typename T >

tData& mds::base::CPartedData< T >::at ( tSize i )

Returns reference to the element [i].

template<typename T >

const tData& mds::base::CPartedData< T >::at ( tSize i ) const

template<typename T >

CPartedData< T > & CPartedData::create ( tSize Size )

Allocates data of a given size.

In case of several references to the existing data, the reference counter is decremented and new data are allocated.
Returns reference to this.

template<typename T >

CPartedData< T > & CPartedData::create	(	tConstDataPtr	pData,

CPartedData< T > & mds::base::CPartedData< T >::create	(	const CPartedData< T > &	Data,
		EMakeRef

Makes a new reference to existing data.

Eventually deallocates the associated data.
Returns reference to this.
