Interface ReportParameterValidator

All Superinterfaces:

Serializable

All Known Implementing Classes:

DefaultReportParameterValidator

public interface ReportParameterValidator
extends Serializable

The report parameter validator is responsible for validating the values provided by the user. The parameters must be valid before the reporting can start. Validation can happen any time in the parametrization process, but will be always executed by the report processor and make the report-processing fail if the validator fails.
