Constructor Detail

JRFillCategoryDataset

public JRFillCategoryDataset(JRCategoryDataset categoryDataset,
                     JRFillObjectFactory factory)

Method Detail

getSeries

public JRCategorySeries[] getSeries()

Specified by:

getSeries in interface JRCategoryDataset

Returns:

an array of JRCategorySeries objects representing the series for category charts

See Also:

JRCategorySeries

customInitialize

protected void customInitialize()

Description copied from class: JRFillElementDataset

Initializes the element dataset.

The dataset is initialized before being used and after each time the dataset gets reset.

Specified by:

customInitialize in class JRFillElementDataset

See Also:

JRFillElementDataset.getResetTypeValue()

customEvaluate

protected void customEvaluate(JRCalculator calculator)
                       throws JRExpressionEvalException

Description copied from class: JRFillElementDataset

Evaluates the expressions associated with the dataset.

Usually, the result of the evaluation would be preserved so that it is used in JRFillElementDataset.customIncrement()

Specified by:

customEvaluate in class JRFillElementDataset

Parameters:

calculator - used to evaluate expressions

Throws:

JRExpressionEvalException - any exception that occurs while evaluating expressions

customIncrement

protected void customIncrement()

Description copied from class: JRFillElementDataset

Increments the dataset by collecting the result of the expression evaluation.

Specified by:

customIncrement in class JRFillElementDataset

getCustomDataset

public org.jfree.data.general.Dataset getCustomDataset()

Specified by:

getCustomDataset in class JRFillChartDataset

getDatasetType

public byte getDatasetType()

Description copied from interface: JRChartDataset

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

Specified by:

getDatasetType in interface JRChartDataset

getLabelGenerator

public Object getLabelGenerator()

Specified by:

getLabelGenerator in class JRFillChartDataset

collectExpressions

public void collectExpressions(JRExpressionCollector collector)

Specified by:

collectExpressions in interface JRElementDataset

getItemHyperlinks

public Map<Comparable<?>,Map<Comparable<?>,JRPrintHyperlink>> getItemHyperlinks()

hasItemHyperlinks

public boolean hasItemHyperlinks()

validate

public void validate(JRVerifier verifier)

Description copied from interface: JRChartDataset

Validates the dataset using a verifier.

Broken rules are collected by the verifier.

Specified by:

validate in interface JRChartDataset

Parameters:

verifier - the verifier to use for validation
