Constructor Summary protected   AbstractPieItemLabelGenerator(String labelFormat, NumberFormat numberFormat, NumberFormat percentFormat)      Creates an item label generator using the specified number formatters. Method Summary public  Object clone()      Returns an independent copy of the generator. protected  Object[] createItemArray(PieDataset dataset, Comparable key)      Creates the array of items that can be passed to the MessageFormat class for creating labels. public  boolean equals(Object obj)      Tests the generator for equality with an arbitrary object. Parameters:   obj - the object to test against (null permitted). protected  String generateSectionLabel(PieDataset dataset, Comparable key)      Generates a label for a pie section. Parameters:   dataset - the dataset (null not permitted). Parameters:   key - the section key (null not permitted). public  String getLabelFormat()      Returns the label format string. public  NumberFormat getNumberFormat()      Returns the number formatter. public  NumberFormat getPercentFormat()      Returns the percent formatter. Constructor Detail AbstractPieItemLabelGenerator protected AbstractPieItemLabelGenerator(String labelFormat, NumberFormat numberFormat, NumberFormat percentFormat)(Code) Creates an item label generator using the specified number formatters. Parameters:   labelFormat - the label format string (null notpermitted). Parameters:   numberFormat - the format object for the values (nullnot permitted). Parameters:   percentFormat - the format object for the percentages(null not permitted). Method Detail clone public Object clone() throws CloneNotSupportedException(Code) Returns an independent copy of the generator. A clone. throws:   CloneNotSupportedException - should not happen. createItemArray protected Object[] createItemArray(PieDataset dataset, Comparable key)(Code) Creates the array of items that can be passed to the MessageFormat class for creating labels. The returned array contains four values: result[0] = the section key converted to a String; result[1] = the formatted data value; result[2] = the formatted percentage (of the total); result[3] = the formatted total value. Parameters:   dataset - the dataset (null not permitted). Parameters:   key - the key (null not permitted). The items (never null). equals public boolean equals(Object obj)(Code) Tests the generator for equality with an arbitrary object. Parameters:   obj - the object to test against (null permitted). A boolean. generateSectionLabel protected String generateSectionLabel(PieDataset dataset, Comparable key)(Code) Generates a label for a pie section. Parameters:   dataset - the dataset (null not permitted). Parameters:   key - the section key (null not permitted). The label (possibly null). getLabelFormat public String getLabelFormat()(Code) Returns the label format string. The label format string (never null). getNumberFormat public NumberFormat getNumberFormat()(Code) Returns the number formatter. The formatter (never null). getPercentFormat public NumberFormat getPercentFormat()(Code) Returns the percent formatter. The formatter (never null).
