LBController¶

constructor¶

LBController(uint iLayerSize);

Creates a LBController with the specified layer size. The layer size must ve a power of two.

iLayerSize

Layer size.

constructor¶

LBController();

Empty constructor.

destructor¶

~LBController();

The destructor.

init¶

int init(int iLayerSize);

Initializes the LBController with the specified layer size. The layer size must ve a power of two.

iLayerSize

Layer size.

addBuffer¶

int addBuffer(LBBase *pLB);

Adds a LBBase object to be managed. This object must have the same layer size as the one the LBController was created for. Furthermore, it must have the same number of layers as any LBBase object that has been addered before.

pLB

The LBBase object to be added.

Returns 0 on success, or negative value at failure.

removeBuffer¶

int removeBuffer(LBBase *pLB);

Remove the specified LBBase.

pLB

The LBBase object to be removed.

Returns 0 on success, or negative value at failure.

addLayer¶

int addLayer();

Add a new layer to the managed buffers. This entails adding a new layer to each buffer and to add an L2List object for it for the new layer.

Returns 0 on success, or negative value at failure.

removeLayer¶

int removeLayer(uint iLayer);

Remove the specified layer from all buffers, as well as the L2List needed for it.

Returns 0 on success, or negative value at failure.

getFreeIndex¶

uint getFreeIndex();

Returns the first free index in the buffers.

deleteElement¶

int  deleteElement(uint lIndex);

Deletes element with given index (i.e. move the correponding node from the ACTIVE to the PASSIVE chain of the L2List)

iIndex

Index of the element to be removed.

Returns 0 on success, or negative value at failure.

int compactData¶

int compactData();

Compactify all buffers.

Returns 0 on success, or negative value at failure.

clear¶

void clear();

Clear all ‘LBBase objects (i.e. mark their elements as PASSIVE in the L2List).

reserveSpace2¶

uint reserveSpace2(uint iNum);

Reserve iNum spaces in each buffer. In fact only L2List is manipulated for this.

iNum

Number of spaces to reserve.

Returns index to first of the reserved element.

getFirstIndex¶

int getFirstIndex(uchar uState) const;

Get the first element of the specified chain.

uState

Either LBController::ACTIVE or LBController::PASSIVE

Retuns the first element of the specified chain.

getNextIndex¶

int getNextIndex(uchar uState, int iCur) const;

Get the next element after iCur in the specified chain.

uState

Either LBController::ACTIVE or LBController::PASSIVE

iCur

Index of element of interest.

Returns the next element after iCur in the specified chain.

getLastIndex¶

int getLastIndex(uchar uState) const;

Get the last element of the specified chain.

uState

Either LBController::ACTIVE or LBController::PASSIVE

Retuns the last element of the specified chain.

getLayerSize¶

uint getLayerSize() const;

Returns the layer size.

getNumLayers¶

uint getNumLayers() const;

Returns number of layers.

getNumUsed¶

uint getNumUsed() const;

Returns number used indexes,

getNumFree¶

uint getNumFree() const;

Returns number of unused indexes.

getNumUsed¶

uint getNumUsed(int i) const;

Returns number of used elements in layer i.

getNumUnused¶

uint getNumUnused(int i) const;

Returns number of unused elements in layer i.

getBufSize¶

int getBufSize(int iDumpMode);

Calculate buffer size required to serialize the LBController with specified dump mode.

iDumpMode

Mode for dumping.

Possible values: LBController::DUMP_MODE_FLAT or LBController::DUMP_MODE_SMART.

serialize¶

uchar *serialize(uchar *pBuf);

Write the serialized LBController into the specified buffer.

pBuf

Buffer to serialize into.

Returns pointer to one position after the end of the serialized data.

deserialize¶

int deserialize(uchar *pBuf);

Creates LBController from serialized data in pBuf.

pBuf

Buffer containing serialized LBController data.

Returns pointer to one position after the end of the serialized data.
