Method Summary

GM_Object	getGeometry() returns the geometry that determines the position the DisplayElement will be rendered to
Symbolizer	getHighlightSymbolizer() returns the symbolizer that determines how the geometry will be rendered if it's highlighted
Symbolizer	getSelectedSymbolizer() returns the symbolizer that determines how the geometry will be rendered if it's selected
Symbolizer	getSymbolizer() Returns the symbolizer that determines how the geometry will be rendered.
void	setGeometry(GM_Object geometry) sets the geometry that determines the position the DisplayElement will be rendered to
void	setHighlightSymbolizer(Symbolizer rule) sets the rule that determines how the geometry will be rendered when it's highlighted
void	setPlacement(java.lang.Object o) Overwrites the default placement of the DisplayElement.
void	setSelectedSymbolizer(Symbolizer rule) sets the rule that determines how the geometry will be rendered when it's selected
void	setSymbolizer(Symbolizer rule) sets the rule that determines how the geometry will be rendered

Method Detail

setPlacement

public void setPlacement(java.lang.Object o)

Overwrites the default placement of the DisplayElement. This method is used by the PlacementOptimizer to minimize the overlapping of labels, for example.

Parameters:

o - the placement to be used

setGeometry

public void setGeometry(GM_Object geometry)

sets the geometry that determines the position the DisplayElement will be rendered to

getGeometry

public GM_Object getGeometry()

returns the geometry that determines the position the DisplayElement will be rendered to

setSymbolizer

public void setSymbolizer(Symbolizer rule)

sets the rule that determines how the geometry will be rendered

Parameters:

rule - symbolizer defining rendering style

getSymbolizer

public Symbolizer getSymbolizer()

Returns the symbolizer that determines how the geometry will be rendered.

setHighlightSymbolizer

public void setHighlightSymbolizer(Symbolizer rule)

sets the rule that determines how the geometry will be rendered when it's highlighted

Parameters:

rule - symbolizer defining rendering style

getHighlightSymbolizer

public Symbolizer getHighlightSymbolizer()

returns the symbolizer that determines how the geometry will be rendered if it's highlighted

setSelectedSymbolizer

public void setSelectedSymbolizer(Symbolizer rule)

sets the rule that determines how the geometry will be rendered when it's selected

Parameters:

rule - symbolizer defining rendering style

getSelectedSymbolizer

public Symbolizer getSelectedSymbolizer()

returns the symbolizer that determines how the geometry will be rendered if it's selected
