void pav::lib::VisualizationImpl::addVisualizer

(

Visualizer

visualizer

throws PAVException [inline]

Adds a new visualizer. The new visualizer will be drawn last. This method automatically tells the visualizer to draw to the applet of this visualization.

Parameters:

visualizer

The visualizer to add. Must not be null

Exceptions:

PAVException

If an error occured while adding the visualizer

Implements pav::lib::Visualization.

void pav::lib::VisualizationImpl::addVisualizer	(	Visualizer	visualizer,
		String	name
	)			throws PAVException [inline]

Adds a new visualizer. The new visualizer will be drawn last. This method automatically tells the visualizer to draw to the applet of this visualization.

Parameters:

	visualizer	The visualizer to add. Must not be null
	name	The name of the visualizer. Must be unique

Exceptions:

PAVException

If an error occured while adding the visualizer

Implements pav::lib::Visualization.

void pav::lib::VisualizationImpl::addVisualizer	(	Visualizer	visualizer,
		int	level,
		String	name
	)			throws PAVException [inline]

Adds a new visualizer with a given level. The level specifies then the visualizer will be told to draw itself relative to the other visualizers. Visualizers with lower levels will be drawn first. If a visualizer with the given level already exists, it will be replaced. This method automatically tells the visualizer to draw to the applet of this visualization.

Parameters:

	visualizer	The visualizer to add. Must not be null
	level	The level
	name	The name of the visualizer. Must be unique

Exceptions:

PAVException

If an error occured while adding the visualizer

Implements pav::lib::Visualization.

void pav::lib::VisualizationImpl::addVisualizer	(	Visualizer	visualizer,
		int	level
	)			throws PAVException [inline]

Adds a new visualizer with a given level. The level specifies then the visualizer will be told to draw itself relative to the other visualizers. Visualizers with lower levels will be drawn first. If a visualizer with the given level already exists, it will be replaced. This method automatically tells the visualizer to draw to the applet of this visualization.

Parameters:

	visualizer	The visualizer to add. Must not be null
	level	The level

Exceptions:

PAVException

If an error occured while adding the visualizer

Implements pav::lib::Visualization.
