        Default constructor.

    • Method Detail

      • init

        public void init​(JRBaseFiller chartFiller,
                 JRFillElementDataset dataset)
        Initializes the chart customizer.
        Parameters:
        chartFiller - the filler instance
        dataset - the fill dataset object

      • getParameterValue

        protected final Object getParameterValue​(String parameterName)
        Returns the value of a report parameter.
        Parameters:
        parameterName - the parameter name
        Returns:
        the value of a report parameter

      • getParameterValue

        protected final Object getParameterValue​(String parameterName,
                                         boolean fromInputDataset)
        Returns the value of a report or input dataset parameter.

        The input dataset differs from the report dataset when the chart uses a sub dataset as input.

        Parameters:
        parameterName - the parameter name
        fromInputDataset - whether the parameter belongs to the input dataset rather than the report.

        This is usefull only when the chart uses a sub dataset as input.

        Returns:
        the value of the parameter

      • getVariableValue

        protected final Object getVariableValue​(String variableName)
        Returns the value of a report variable.
        Parameters:
        variableName - the variable name
        Returns:
        the value of a report variable

      • getVariableValue

        protected final Object getVariableValue​(String variableName,
                                        boolean fromInputDataset)
        Returns the value of a report or input dataset variable.

        The input dataset differs from the report dataset when the chart uses a sub dataset as input.

        Parameters:
        variableName - the variable name
        fromInputDataset - whether the variable belongs to the input dataset rather than the report.

        This is usefull only when the chart uses a sub dataset as input.

        Returns:
        the value of the variable

      • getFieldValue

        protected final Object getFieldValue​(String fieldName)
        Returns the value of a report field.
        Parameters:
        fieldName - the field name
        Returns:
        the value of a report field

      • getFieldValue

        protected final Object getFieldValue​(String fieldName,
                                     boolean fromInputDataset)
        Returns the value of a report or input dataset field.

        The input dataset differs from the report dataset when the chart uses a sub dataset as input.

        Parameters:
        fieldName - the field name
        fromInputDataset - whether the field belongs to the input dataset rather than the report.

        This is usefull only when the chart uses a sub dataset as input.

        Returns:
        the value of the field

      • getFiller

        public JRBaseFiller getFiller()

        Parameters:
        filler - the filler to set

      • setChartDataset

        public void setChartDataset​(JRFillElementDataset chartDataset)
        Parameters:
        chartDataset - the chartDataset to set
