Constructor Detail

JRFillHighLowDataset

public JRFillHighLowDataset(JRHighLowDataset dataset,
                            JRFillObjectFactory factory)

Method Detail

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

evaluateSectionHyperlink

protected void evaluateSectionHyperlink(JRCalculator calculator)
                                 throws JRExpressionEvalException

Throws:

JRExpressionEvalException

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

getLabelGenerator

public java.lang.Object getLabelGenerator()

Specified by:

getLabelGenerator in class JRFillChartDataset

getSeriesExpression

public JRExpression getSeriesExpression()

Specified by:

getSeriesExpression in interface JRHighLowDataset

getDateExpression

public JRExpression getDateExpression()

Specified by:

getDateExpression in interface JRHighLowDataset

getHighExpression

public JRExpression getHighExpression()

Specified by:

getHighExpression in interface JRHighLowDataset

getLowExpression

public JRExpression getLowExpression()

Specified by:

getLowExpression in interface JRHighLowDataset

getOpenExpression

public JRExpression getOpenExpression()

Specified by:

getOpenExpression in interface JRHighLowDataset

getCloseExpression

public JRExpression getCloseExpression()

Specified by:

getCloseExpression in interface JRHighLowDataset

getVolumeExpression

public JRExpression getVolumeExpression()

Specified by:

getVolumeExpression in interface JRHighLowDataset

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

collectExpressions

public void collectExpressions(JRExpressionCollector collector)

Specified by:

collectExpressions in interface JRElementDataset

getItemHyperlink

public JRHyperlink getItemHyperlink()

Description copied from interface: JRHighLowDataset

Returns the hyperlink specification for chart items.

The hyperlink will be evaluated for every chart item and a image map will be created for the chart.

Specified by:

getItemHyperlink in interface JRHighLowDataset

Returns:

hyperlink specification for chart items

hasItemHyperlink

public boolean hasItemHyperlink()

getItemHyperlinks

public java.util.List<JRPrintHyperlink> getItemHyperlinks()

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
