Method Detail

getGeometryPropertyName

public java.lang.String getGeometryPropertyName()

Description copied from interface: PointSymbolizer

This property defines the geometry to be used for styling.
The property is optional and if it is absent (null) then the "default" geometry property of the feature should be used. Geometry types other than inherently point types can be used. The geometryPropertyName is the name of a geometry property in the Feature being styled. Typically, features only have one geometry so, in general, the need to select one is not required. Note: this moves a little away from the SLD spec which provides an XPath reference to a Geometry object, but does follow it in spirit.

Specified by:

getGeometryPropertyName in interface PointSymbolizer

Returns:

String The name of the attribute in the feature being styled that should be used. If null then the default geometry should be used.

setGeometryPropertyName

public void setGeometryPropertyName(java.lang.String name)

Sets the Geometry Property Name.

Specified by:

setGeometryPropertyName in interface PointSymbolizer

Parameters:

name - The Geometry Property Name.

getGraphic

public Graphic getGraphic()

Provides the graphical-symbolization parameter to use for the point geometry.

Specified by:

getGraphic in interface PointSymbolizer

Returns:

The Graphic to be used when drawing a point

setGraphic

public void setGraphic(Graphic graphic)

Setter for property graphic.

Specified by:

setGraphic in interface PointSymbolizer

Parameters:

graphic - New value of property graphic.

accept

public void accept(StyleVisitor visitor)

Accept a StyleVisitor to perform an operation on this symbolizer.

Specified by:

accept in interface Symbolizer

Parameters:

visitor - The StyleVisitor to accept.

clone

public java.lang.Object clone()

Creates a deep copy clone.

Specified by:

clone in interface org.opengis.util.Cloneable

Overrides:

clone in class AbstractGTComponent

Returns:

The deep copy clone.

Throws:

java.lang.RuntimeException - DOCUMENT ME!

hashCode

public int hashCode()

Generates the hashcode for the PointSymbolizer

Returns:

the hashcode

equals

public boolean equals(java.lang.Object oth)

Checks this PointSymbolizerImpl with another for equality.

Two PointSymbolizers are equal if the have the same geometry property name and their graphic object is equal.

Note: this method only works for other instances of PointSymbolizerImpl, not other implementors of PointSymbolizer

Parameters:

oth - The object to compare with this PointSymbolizerImpl for equality.

Returns:

True of oth is a PointSymbolizerImpl that is equal.
