public class WeatherInput

extends InputSource

Gets weather information for a given location: high temperature, low temperature, forecast (e.g., "sunny," "partly cloudy"), wind speeds and direction, and the chance of rain (in percent). The metadata of the events this class creates is WeatherConstants.WEATHER.

Field Summary

static java.lang.String	MY_ID The unique ID String for this input, found in WeatherConstants, which is an application specific class.
static java.lang.String	URL The location string at the end of the Yahoo Weather URL.

Constructor Detail

WeatherInput

public WeatherInput()

Constructor for non-distributed applications. An input that uses this constructor cannot be part of an application on another machine.

WeatherInput

public WeatherInput(java.lang.String my_ip)

Constructor for distributed applications. An input that uses this constructor can send evets to remote applications.

Method Detail

newInput

public Events newInput()

Gets the high temperature, low temperature, forecast, wind, barometric pressure, humidity, sunrise, and sunset from the Yahoo weather webpage for today in a user-specified location. Set the location when this parser is initialized. The Event with these pieces of data is returned to be dispatched to the PTK server and eventually sent to outputs that subscribe to its metadata. Uses the PTKWebPageParser class to parse the Yahoo Web page.

Specified by:

newInput in class InputSource

Returns:

Event a Event object that contains the weather information.

main

public static void main(java.lang.String[] argsv)

This main method allows the input to run, continually getting new input and dispatching the data in events to the PTK server.
