Method Details

addSymbol

int addSymbol(ISymbol newSymbol)

Adds a new ISymbol to the layer to be used to render the Geometry objects. The symbol will be added to the legend of the layer.

Parameters:

newSymbol - the ISymbol to add

Returns:

an identifier of the symbol to be used when adding geometries

getSymbol

ISymbol getSymbol(int symbolId)

Returns the ISymbol of the layer with the given identifier.

Parameters:

symbolId - the symbol identifier

Returns:

the symbol with the given id or null if there is not any symbol registered with that id

getSymbolId

int getSymbolId(ISymbol symbol)

Returns the identifier of the symbol into the layer.

Parameters:

symbol - the symbol to look for

Returns:

the symbol identifier or -1 if it is not registered into the layer

addGraphic

void addGraphic(org.gvsig.fmap.geom.Geometry geom,
 int idsym)

addGraphic

void addGraphic(org.gvsig.fmap.geom.Geometry geom,
 int idsym,
 String label)

addGraphic

void addGraphic(String groupId,
 org.gvsig.fmap.geom.Geometry geom,
 int idsym)

Adds a new Geometry to be rendered into the layer.

Parameters:

groupId - group identifier. Allows to identify a group of Geometry added to the layer

geom - the Geometry to add

idsym - the ISymbol identifier to apply to render the Geometry

addGraphic

void addGraphic(String groupId,
 org.gvsig.fmap.geom.Geometry geom,
 int idsym,
 String label)

Adds a new Geometry to be rendered into the layer.

Parameters:

groupId - group identifier. Allows to identify a group of Geometry added to the layer

geom - the Geometry to add

idsym - the ISymbol identifier to apply to render the Geometry

label - the text to show if the ISymbol is a ITextSymbol. Set null otherwise.

addGraphic

void addGraphic(String groupId,
 org.gvsig.fmap.geom.Geometry geom,
 int idsym,
 String label,
 Object tag,
 int priority)

Adds a new Geometry to be rendered into the layer.

Parameters:

groupId - group identifier. Allows to identify a group of Geometry added to the layer
