FeatureTypeStyleImpl

protected FeatureTypeStyleImpl(Rule[] rules)

Creates a new instance of FeatureTypeStyleImpl

Parameters:

rules - DOCUMENT ME!

FeatureTypeStyleImpl

protected FeatureTypeStyleImpl(List<Rule> arules)

FeatureTypeStyleImpl

protected FeatureTypeStyleImpl()

Creates a new instance of FeatureTypeStyleImpl

FeatureTypeStyleImpl

public FeatureTypeStyleImpl(FeatureTypeStyle fts)

Method Detail

rules

public List<Rule> rules()

Description copied from interface: FeatureTypeStyle

Rules govern the appearance of any given feature to be styled by this styler.

This is *the* list being used to manage the rules!

Specified by:

rules in interface FeatureTypeStyle

Returns:

the list of rules. can not be null but can be empty.

getRules

@Deprecated
public Rule[] getRules()

Deprecated.

Description copied from interface: FeatureTypeStyle

Rules govern the appearance of any given feature to be styled by this styler. Each rule contains conditions based on scale and feature attribute values. In addition, rules contain the symbolizers which should be applied when the rule holds true.

Returns:

The full set of rules contained in this styler.

setRules

@Deprecated
public void setRules(Rule[] newRules)

Deprecated.

Description copied from interface: FeatureTypeStyle

Rules govern the appearance of any given feature to be styled by this styler. Each rule contains conditions based on scale and feature attribute values. In addition, rules contain the symbolizers which should be applied when the rule holds true.

Parameters:

newRules - The set of rules to be set for this styler.

addRule

@Deprecated
public void addRule(Rule rule)

Deprecated.

semanticTypeIdentifiers

public Set<SemanticType> semanticTypeIdentifiers()

Description copied from interface: FeatureTypeStyle

Returns a collection that identifies the more general "type" of geometry that this style is meant to act upon. In the current OGC SE specifications, this is an experimental element and can take only one of the following values:

• generic:point
• generic:line
• generic:polygon
• generic:text
• generic:raster
• generic:any

Specified by:

semanticTypeIdentifiers in interface FeatureTypeStyle

getSemanticTypeIdentifiers

@Deprecated
public String[] getSemanticTypeIdentifiers()

Deprecated.

Description copied from interface: FeatureTypeStyle

The SemanticTypeIdentifiers is experimental and is intended to be used to identify, using a community-controlled name(s), what the style is suitable to be used for. For example, a single style may be suitable to use with many different feature types. The syntax of the SemanticTypeIdentifiers string is undefined, but the strings "generic:line_string", "generic:polygon", "generic:point", "generic:text", "generic:raster", and "generic:any" are reserved to indicate that a FeatureTypeStyle may be used with any feature type with the corresponding default geometry type (i.e., no feature properties are referenced in the feature type style).

This method will be replaced by a live set semanticIdentifiers() in 2.6.x

Returns:

An array of strings representing systematic types which could be styled by this instance.

setSemanticTypeIdentifiers

@Deprecated
public void setSemanticTypeIdentifiers(String[] types)

Deprecated.

Description copied from interface: FeatureTypeStyle

The SemanticTypeIdentifiers is experimental and is intended to be used to identify, using a community-controlled name(s), what the style is suitable to be used for. For example, a single style may be suitable to use with many different feature types. The syntax of the SemanticTypeIdentifiers string is undefined, but the strings "generic:line_string", "generic:polygon", "generic:point", "generic:text", "generic:raster", and "generic:any" are reserved to indicate that a FeatureTypeStyle may be used with any feature type with the corresponding default geometry type (i.e., no feature properties are referenced in the feature type style).

Parameters:

types - An array of strings representing systematic types which could be styled by this instance.

featureTypeNames

public Set<Name> featureTypeNames()

Description copied from interface: FeatureTypeStyle

Returns the names of the feature type that this style is meant to act upon.

In OGC Symbology Encoding define this method to return a single String, and ISO 19117 use a Collection of String. We've choosen ISO because it is more logic that a featureTypeStyle can be applied to multiple featuretypes and not limited to a single one.

Specified by:

featureTypeNames in interface FeatureTypeStyle

Returns:

the name of the feature type that this style is meant to act upon.

getFeatureTypeName

@Deprecated
public String getFeatureTypeName()

Deprecated.

Description copied from interface: FeatureTypeStyle

Only features with the type name returned by this method should be styled by this feature type styler.

Returns:

The name of types that this styler applies to

setFeatureTypeName

@Deprecated
public void setFeatureTypeName(String name)

Deprecated.

Description copied from interface: FeatureTypeStyle

Sets the type name of the features that this styler should be applied to.

Parameters:

name - The TypeName of the features to be styled by this instance.

getFeatureInstanceIDs

public Id getFeatureInstanceIDs()

Description copied from interface: FeatureTypeStyle

Returns a collection of Object identifying features object.

ISO 19117 extends FeatureTypeStyle be providing this method. This method enable the possibility to use a feature type style on a given list of features only, which is not possible in OGC SE.

Specified by:

getFeatureInstanceIDs in interface FeatureTypeStyle

Returns:

Collection

getDescription

public Description getDescription()

Description copied from interface: FeatureTypeStyle

Description for this style.

Specified by:

getDescription in interface FeatureTypeStyle

Returns:

Human readable description for use in user interfaces

getName

public String getName()

Description copied from interface: FeatureTypeStyle

Returns a name for this style. This can be any string that uniquely identifies this style within a given canvas. It is not meant to be human-friendly. (The "title" property is meant to be human friendly.)

Specified by:

getName in interface FeatureTypeStyle

Returns:

a name for this style.

setName

public void setName(String name)

getAbstract

@Deprecated
public String getAbstract()

Deprecated.

setAbstract

@Deprecated
