Constructor Detail

WeatherDatabase

public WeatherDatabase(Map<String,String> prop)

Constructs a new database collector. The properties of this collector are also used to generate the databank access object, this means that the properties defined in the GenericSql class must also be present here if non-default values are wanted. Additionally, the weather trigger stub is constructed here with the generic properties of the collector.

Method Detail

init

public void init()

Initializes the database current object as well as the database acess object. For the sql connsction, this means calling it GenericSql#init method and opening the connection.
For the current database collector, its essential mappes (principal, #minima, and #maxima) are assigned. Additionally, the format look-up table is constructed using the class names pointed to in the #KEY_FORMAT property to java classes. Only classes found that also support a single-string constructor are used.

Specified by:

init in interface Initializable

Overrides:

init in class AbstractSql

getWeatherData

public List<WeatherSurveying.DataBlock> getWeatherData(Date fromsharp,
                                                       Date tosharp)

Returns a list of mappings of sensor names to sensor values. As no sigma/min/max value is stored in the database, this info is lost.

Returns:

A list of WeatherSurveying.BlockData objects.
