Method Detail

getDescription

public DescriptionImpl getDescription()

Description copied from interface: Style

Description for this style.

getDescription in interface Style

Returns:

Human readable description for use in user interfaces

getFeatureTypeStyles

public FeatureTypeStyle[] getFeatureTypeStyles()

featureTypeStyles

public List<FeatureTypeStyle> featureTypeStyles()

Description copied from interface: Style

FeatureTypeStyles rendered in order of appearance in this list.

Specified by:

featureTypeStyles in interface Style

getDefaultSpecification

public Symbolizer getDefaultSpecification()

Description copied from interface: Style

This functionality is from an ISO specificaiton; and conflicts with the idea of an else rule presented by SLD.

Implementations may choose to look up the first symbolizer of an elseFilter or allow this to be provided?

Specified by:

getDefaultSpecification in interface Style

Returns:

Symbolizer to use if no rules work out.

setDefaultSpecification

public void setDefaultSpecification(Symbolizer defaultSymbolizer)

Parameters:

defaultSymbolizer - To be used if a feature is not rendered by any of the rules

setFeatureTypeStyles

public void setFeatureTypeStyles(FeatureTypeStyle... styles)

addFeatureTypeStyle

getName

public String getName()

Description copied from interface: Style

Style name (machine readable, don't show to users)

Specified by:

getName in interface Style

isDefault

public boolean isDefault()

Description copied from interface: Style

The IsDefault element identifies whether a style is the default style of a layer, for use in SLD ‘library mode’ when rendering or for storing inside of a map server. IsDefault uses “1” or “true” for true and “0” or “false” for false. The default value is “0”.

Specified by:

isDefault in interface Style

setDefault

public void setDefault(boolean isDefault)

Description copied from interface: Style

Indicates that this is the default style.

Assume this is kept for GeoServer enabling a WMS to track which style is considered the default. May consider providing a clientProperties mechanism similar to Swing JComponent allowing applications to mark up the Style content for custom uses.
