用法

#!/usr/bin/env python#coding=utf-8# The following example shows the basic usage of bRingBuf classfrombringbuf.bringbufimportbRingBuf# define a ring buffer with the size of 5 bytesbuf=bRingBuf(5)# the buffers length initially is zeroprint(buf.len)# check if buffer is empty (True)print(buf.is_empty())# enqueue 6 bytes to the buffer# (note that the buffer will overflow)buf.enqueue([0x01,0x02,0x03,0x04,0x05,0x06])# now five bytes are in the buffer (maximal number of bytes)print(buf.len)# check if buffer is empty (False)print(buf.is_empty())# read content of the whole buffer without removing any bytesprint(buf.read(buf.len))# read and remove three bytes from the bufferprint(buf.dequeue(3))# read content of the whole buffer without removing any bytesprint(buf.read(buf.len))# enque four new bytesbuf.enqueue([0x07,0x08,0x09])# read content of the whole buffer without removing any bytesprint(buf.read(buf.len))# check whether buffer contains a pattern?# this might be solved by buf.index, which also returns the index,# but this is a more descriptive way to checkprint(buf.contains([0x02,0x08]),buf.contains([0x07,0x08,0x09]))# index of patternsprint(buf.index([0x02,0x08]),buf.index([0x07,0x08,0x09]))# contains pattern (with offset)?print(buf.contains([0x02,0x08],2),buf.contains([0x07,0x08,0x09],offset=2))# index of patterns (with offset)print(buf.index([0x02,0x08],2),buf.index([0x07,0x08,0x09],2))# read with offsetprint(buf.read(3,3))# enqueue a single bytebuf.enqueue_byte(0xff)print(buf.read(buf.len))# dequeue a single byteprint(buf.dequeue_byte())
