Method Detail

getPlot

public Plot getPlot()

Returns the plot that occupies the entity area.

Returns:

The plot (never null).

Overrides:

equals in class ChartEntity

Parameters:

obj - the object to test against (null permitted).

Returns:

A boolean.

canEqual

public boolean canEqual(java.lang.Object other)

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