Method Details

generateToolTip

public String generateToolTip(CategoryDataset dataset,
 int row,
 int column)

Generates the tool tip text for an item in a dataset. Note: in the current dataset implementation, each row is a series, and each column contains values for a particular category.

Specified by:

generateToolTip in interface CategoryToolTipGenerator

Parameters:

dataset - the dataset (null not permitted).

row - the row index (zero-based).

column - the column index (zero-based).

Returns:

The tooltip text (possibly null).

equals

public boolean equals(Object obj)

Tests this generator for equality with an arbitrary object.

Overrides:

equals in class AbstractCategoryItemLabelGenerator

Parameters:

obj - the object (null permitted).

Returns:

A boolean.

canEqual

public boolean canEqual(Object other)

Ensures symmetry between super/subclass implementations of equals. For more detail, see http://jqno.nl/equalsverifier/manual/inheritance.

Overrides:

canEqual in class AbstractCategoryItemLabelGenerator

Parameters:

other - Object

Returns:

true ONLY if the parameter is THIS class type

hashCode

public int hashCode()

Description copied from class: AbstractCategoryItemLabelGenerator

Returns a hash code for this instance.

Overrides:

hashCode in class AbstractCategoryItemLabelGenerator

Returns:

A hash code.
