Introduction

This classes allowes the user to build up own BayEOS-Device implementations in PHP

BayEOSWriter-Class

BayEOSWriter reads data either directly (sensor) or via different ways of communication (XBee, QLI, ...) and stores data in files in a queue directory

Example: BayEOSWriter.php

Storage structure:

BayEOSWriter only has one active file. Ending is ".act" Finished files have the ending ".rd" Per default exported files will get deleted. If "rm" is set to FALSE, files are kept as ".bak" files in the queue directory

File formate is binary. For each frame there is [timestamp double][length short][frame]

BayEOSSender-Class

BayEOSSender looks for finished data files in queue-directory and trys to send the data to the configured BayEOS-Gateway

Example: BayEOSSender.php

BayEOSSimpleClient-Class

BayEOSSimpleClient combines Write and Sender. The constructor automatically forks of one sender. Using BayEOSSimpleClient is probably the simpliest way to write own scripts.

Example: MySimpleClient.php

BayEOSGatewayClient

BayEOSGatewayClient is a wrapper class. Only works on systems with fork! It forks two processes for each device: one writer, one sender

To make use of the class one has do derive a class and overwrite the BayEOSGatewayClient::readData()

To set up a routing devices (e.g. XBee) one has to additionaly overwrite the BayEOSGatewayClient::saveData($data)

To init a writer process, one can overwrite BayEOSGatewayClient::initWriter()

Example: MyClient.php

BayEOSType-Class

BayEOSType is a helper Class to do binary transformations...
