public interface JRChartDataset
extends JRElementDataset

Datasets are used to represent the actual data needed to generate a chart. The dataset structure may vary with each chart type. This is the superinterface for all datasets and contains common dataset properties.

Method Detail

getDatasetType

byte getDatasetType()

Gets the dataset type. Must be one of the dataset type constants defined in this class.

validate

void validate(JRVerifier verifier)

Validates the dataset using a verifier.

Broken rules are collected by the verifier.

Parameters:

verifier - the verifier to use for validation
