Detailed Description

Implements a ring buffer. It is not possible to create plane copies of this class. It is not possible to use the default constructor.

RingBuffer::RingBuffer ( OpcUa_UInt32 uSize )

construction

Parameters:

uSize

the size of the buffer

RingBuffer::~RingBuffer ( )

destruction

void RingBuffer::changeSize ( OpcUa_UInt32 newSize )

Change size of the buffer.

Parameters:

newSize

the new size the buffer will get.

OpcUa_UInt32 RingBuffer::getSize ( )

Get size of the buffer.

OpcUa_UInt32 RingBuffer::getCount ( )

Get number of data pieces in the buffer.

OpcUa_StatusCode RingBuffer::pushSafe ( OpcUa_Void * pData )

Push data to the buffer. Returns an error if the buffer is full.

Parameters:

pData

Data to push into the buffer.

OpcUa_Void * RingBuffer::push ( OpcUa_Void * pData )

Push data to the buffer. Adds the data and returns the oldest data if the buffer is full.

Parameters:

pData

Data to push into the buffer.

OpcUa_Void * RingBuffer::pop ( )

Pop the data from the buffer.
