ost::FixedBuffer(3) Library Functions Manual ost::FixedBuffer(3) NAME
ost::FixedBuffer - A buffer class that holds a known capacity of fixed sized objects defined during creation. SYNOPSIS
#include <buffer.h> Inherits ost::Buffer. Public Member Functions FixedBuffer (size_t capacity, size_t objsize) Create a buffer of known capacity for objects of a specified size. FixedBuffer (const FixedBuffer &fb) Create a copy of an existing fixed size buffer and duplicate it's contents. virtual ~FixedBuffer () Destroy the fixed buffer and free the memory used to store objects. FixedBuffer & operator= (const FixedBuffer &fb) bool isValid (void) Protected Member Functions size_t onPeek (void *buf) Return the first object in the buffer. size_t onWait (void *buf) Wait for and return a fixed object in the buffer. size_t onPost (void *buf) Post an object of the appropriate size into the buffer. Additional Inherited Members Detailed Description A buffer class that holds a known capacity of fixed sized objects defined during creation. Author: David Sugar dyfet@ostel.com producer/consumer buffer for fixed size objects. Constructor &; Destructor Documentation ost::FixedBuffer::FixedBuffer (size_tcapacity, size_tobjsize) Create a buffer of known capacity for objects of a specified size. Parameters: capacity of the buffer. objsize for each object held in the buffer. ost::FixedBuffer::FixedBuffer (const FixedBuffer &fb) Create a copy of an existing fixed size buffer and duplicate it's contents. Parameters: fb existing FixedBuffer object. virtual ost::FixedBuffer::~FixedBuffer () [virtual] Destroy the fixed buffer and free the memory used to store objects. Member Function Documentation bool ost::FixedBuffer::isValid (void) [virtual] Reimplemented from ost::Buffer. size_t ost::FixedBuffer::onPeek (void *buf) [protected], [virtual] Return the first object in the buffer. Returns: predefined size of this buffers objects. Parameters: buf pointer to copy contents of head of buffer to. Implements ost::Buffer. size_t ost::FixedBuffer::onPost (void *buf) [protected], [virtual] Post an object of the appropriate size into the buffer. Returns: predefined size of this buffers objects. Parameters: buf pointer to data to copy into the buffer. Implements ost::Buffer. size_t ost::FixedBuffer::onWait (void *buf) [protected], [virtual] Wait for and return a fixed object in the buffer. Returns: predefined size of this buffers objects. Parameters: buf pointer to hold object returned from the buffer. Implements ost::Buffer.
