public ISymbol getDefaultSymbol()

Description copied from interface: IVectorLegend

Obtains the default symbol of the legend.

Specified by:

getDefaultSymbol in interface ILegend

Specified by:

getDefaultSymbol in interface IVectorLegend

Returns:

default symbol.

getShapeType

public int getShapeType()

Description copied from interface: IVectorLegend

Returns the type of the shape.

Specified by:

getShapeType in interface IVectorLegend

Returns:

Returns the type of the shapes that the legend is ready to use.

setShapeType

public void setShapeType(int shapeType)

Description copied from interface: IVectorLegend

Defines the type of the shape.

Specified by:

setShapeType in interface IVectorLegend

Parameters:

shapeType - type of the shape.

getSymbolByFeature

public ISymbol getSymbolByFeature(Feature feat)

Description copied from interface: IVectorLegend

Returns a symbol starting from an IFeature.

Specified by:

getSymbolByFeature in interface IVectorLegend

Parameters:

feat - IFeature.

Returns:

Símbolo.

useDefaultSymbol

public void useDefaultSymbol(boolean b)

Specified by:

useDefaultSymbol in interface IVectorLegend

getUsedFields

public String[] getUsedFields()

isUseDefaultSymbol

public boolean isUseDefaultSymbol()

Description copied from interface: IVectorLegend

Returns true or false depending on if the rest of values are used.

Specified by:

isUseDefaultSymbol in interface IVectorLegend

Returns:

True if the rest of values are used.

getClassName

public String getClassName()

isSuitableForShapeType

public boolean isSuitableForShapeType(int shapeType)

Specified by:

isSuitableForShapeType in interface IVectorLegend

setFeatureStore

public void setFeatureStore(FeatureStore fs)
                     throws DataException

Throws:

DataException

getRequiredFeatureAttributeNames

protected String[] getRequiredFeatureAttributeNames(FeatureStore featureStore)
                                             throws DataException

Description copied from class: AbstractVectorialLegend

Returns the names of the Feature attributes required for the ILegend to operate.

Specified by:

getRequiredFeatureAttributeNames in class AbstractVectorialLegend

Parameters:

featureStore - the store where the Features belong to

Returns:

the names of required Feature attribute names

Throws:

DataException - if there is an error getting the attribute names

clone

public Object clone()
             throws CloneNotSupportedException

Description copied from interface: Cloneable

Creates a copy of the object.

Overrides:

clone in class AbstractVectorialLegend

Returns:

a copy of the object

Throws:

CloneNotSupportedException - if the instance of the object cannot be cloned. As this is extending Cloneable so its sure it implements it, so this exception may be used for problems on specific object instances.
