setConstraint in interface LayoutDirector

invalidateLayout

public void invalidateLayout(PlotEx plot)

Description copied from interface: LayoutDirector

Invalidates the layout, indicating that if the layout manager has cached information it should be discarded.

layout in interface LayoutDirector

getPreferredContentSize

public java.awt.geom.Dimension2D getPreferredContentSize(PlotEx plot)

Calculate the preferred content size of the given plot. The default implementation returns the plot.getPreferredContentSize(), which can be override by subclass to consider nested subplots. The returned size may be null if there is no enough information to derive a value.

Specified by:

getPreferredContentSize in interface LayoutDirector

Parameters:

plot -

Returns:

the preferred content size

getPreferredSize

public java.awt.geom.Dimension2D getPreferredSize(PlotEx plot)

Description copied from interface: LayoutDirector

Returns the preferred size of the given plot.

Specified by:

getPreferredSize in interface LayoutDirector

Parameters:

plot - The plot

Returns:

The preferred size

toString

public java.lang.String toString()
