Direct Known Subclasses:

AbstractTimeSeries

public abstract class AbstractQuery
extends BackgroundJob

This abstract class represents all queries. A query returns a matrix containing all information which are computed. The Headings are used to identify the information of each column.
The view for each query is constructed by a meta model which checks all classes for getter/setter methods annotated with the SetProperty and GetProperty annotations. For each getter/setter pair there is one text field displayed. All parameters and return values of the annotated methods have to be strings. These methods may throw a SetDataException if the setter parameter received from the text field is wrongly formatted. The error message of the exception will be displayed to the user. For a detailed example see Consultations.
