Detailed Description

A Symbolizer describes how a feature is to appear on a map.

A Symbolizer is an abstract type for encoding the graphical properties used to portray geographic information. Concrete Symbolizers are derived from this base type. A Symbolizer describes how a feature is to appear on a map. The Symbolizer describes not just the shape that should appear but also such graphical properties as color and opacity. A Symbolizer is obtained by specifying one of a small number of different types of Symbolizers and then supplying parameters to override its default behaviour. Five types of Symbolizers are defined:

Line
Polygon
Point
Text
Raster

Concrete Symbolizer types are derived from this base type.

Constructor & Destructor Documentation

te::se::Symbolizer::Symbolizer ( )

It initializes a new Symbolizer.

te::se::Symbolizer::Symbolizer ( const Symbolizer & rhs )

Copy constructor.

Parameters

rhs	The other symbolizer.

virtual te::se::Symbolizer::~Symbolizer ( )

virtual

Virtual destructor.

Member Function Documentation

virtual ReturnType te::common::BaseVisitable< Visitor , void >::accept ( VisitorType & guest ) const

pure virtualinherited

It call the visit method from the guest object.

Parameters

guest The guest or visitor.

Returns: Any valid value define by the template type R.

virtual Symbolizer* te::se::Symbolizer::clone ( ) const

pure virtual

It creates a new copy of this object.

Implemented in te::se::PolygonSymbolizer, te::se::RasterSymbolizer, te::se::LineSymbolizer, te::se::TextSymbolizer, and te::se::PointSymbolizer.

const te::xl::SimpleLink* te::se::Symbolizer::getBaseSymbolizer ( ) const

const Description* te::se::Symbolizer::getDescription ( ) const

const std::string& te::se::Symbolizer::getName ( ) const

virtual const std::string& te::se::Symbolizer::getType ( ) const

pure virtual

It returns the symbolizer type.

Returns: The symbolizer type.

Implemented in te::se::PolygonSymbolizer, te::se::RasterSymbolizer, te::se::LineSymbolizer, te::se::TextSymbolizer, and te::se::PointSymbolizer.

const te::common::BaseUnitOfMeasure* te::se::Symbolizer::getUom ( ) const

const std::string& te::se::Symbolizer::getVersion ( ) const

void te::se::Symbolizer::setBaseSymbolizer ( te::xl::SimpleLink * baseSymbolizer )

void te::se::Symbolizer::setDescription ( Description * d )

void te::se::Symbolizer::setName ( const std::string & name )

void te::se::Symbolizer::setUom ( const te::common::BaseUnitOfMeasure * uom )

It sets the unit-of-measure.

All Symbolizers include an optional gml:uom-attribute as used by GML (this is set inside the abstract SymbolizerType and therefore inherited by all Symbolizers). This applies to all elements included inside a Symbolizer such as stroke-width, size, font-size, Gap, InitialGap, Displacement and PerpendicularOffset. If no uom is set inside of Symbolizer, all units are measured in pixel, the behaviour used by SLD 1.0.0. The following uom definitions are recommended to be used:

void te::se::Symbolizer::setVersion ( const std::string & version )
