Class AbstractSymbolizer

java.lang.Object
  org.deegree.graphics.sld.AbstractSymbolizer

All Implemented Interfaces:

Symbolizer

Direct Known Subclasses:

LineSymbolizer, PointSymbolizer, PolygonSymbolizer, RasterSymbolizer, TextSymbolizer

public abstract class AbstractSymbolizer
extends java.lang.Object
implements Symbolizer

This is the basis of all symbolizers. It defines the method getGeometry that's common to all symbolizers.

Method Detail

getGeometry

public Geometry getGeometry()

The Geometry element is optional and if it is absent then the default geometry property of the feature type that is used in the containing FeatureStyleType is used. The precise meaning of default geometry property is system-dependent. Most frequently, feature types will have only a single geometry property.

Specified by:

getGeometry in interface Symbolizer

Returns:

the geometry of the symbolizer

setGeometry

public void setGeometry(Geometry geometry)

sets the

Specified by:

setGeometry in interface Symbolizer

Parameters:

geometry - the geometry of the symbolizer

getMinScaleDenominator

public double getMinScaleDenominator()

Description copied from interface: Symbolizer

The ScaleDenominator-information is optional and determines whether a rule (and thus a Symbolizer) is a to be applied at a certain scale.

Specified by:

getMinScaleDenominator in interface Symbolizer

Returns:

the MinScaleDenominator

setMinScaleDenominator

public void setMinScaleDenominator(double minDenominator)

Description copied from interface: Symbolizer

Sets the MinScaleDenominator

Specified by:

setMinScaleDenominator in interface Symbolizer

Parameters:

minDenominator - the MinScaleDenominator

getMaxScaleDenominator

public double getMaxScaleDenominator()

Description copied from interface: Symbolizer

The ScaleDenominator-information is optional and determines whether a rule (and thus a Symbolizer) is a to be applied at a certain scale.

Specified by:

getMaxScaleDenominator in interface Symbolizer

Returns:

the MaxScaleDenominator

setMaxScaleDenominator

public void setMaxScaleDenominator(double maxDenominator)

Description copied from interface: Symbolizer

Sets the MaxScaleDenominator

Specified by:

setMaxScaleDenominator in interface Symbolizer

Parameters:

maxDenominator - the MaxScaleDenominator

getResponsibleClass

public java.lang.String getResponsibleClass()

returns the name of a class that will be used for rendering the current symbolizer. This enables a user to define his own rendering class (DisplayElement) for a symbolizer to realize styles/renderings that can't be defined using SLD at the moment.
The returned class must extend org.deegree_impl.graphics.displayelements.GeometryDisplayElement_Impl
For default the method returns the deegree default class name for rendering the current symbolizer.

Returns:

the name of a class that will be used for rendering the current symbolizer.

setResponsibleClass

public void setResponsibleClass(java.lang.String responsibleClass)

sets a class that will be used for rendering the current symbolizer. This enables a user to define his own rendering class (DisplayElement) for a symbolizer to realize styles/renderings that can't be defined using SLD at the moment.
The passed class must extend org.deegree_impl.graphics.displayelements.GeometryDisplayElement_Impl

Parameters:

responsibleClass -
