Method Detail

getSymbolByFeature

ISymbol getSymbolByFeature(Feature feat)
                           throws MapContextException

Returns a symbol starting from an IFeature. TAKE CARE!! When we are using a feature iterator as a database the only field that will be filled is the fieldID. The rest of fields will be null to reduce the time of creation

Parameters:

feat - IFeature.

Returns:

Símbolo.

Throws:

MapContextException

getShapeType

int getShapeType()

Returns the type of the shape.

Returns:

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

setShapeType

void setShapeType(int shapeType)

Defines the type of the shape.

Parameters:

shapeType - type of the shape.

setDefaultSymbol

void setDefaultSymbol(ISymbol s)

Establishes the default symbol of a legend. In a SingleSymbolLegend the symbol is established by calling this method.

Parameters:

s - default symbol.

isUseDefaultSymbol

boolean isUseDefaultSymbol()

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

Returns:

True if the rest of values are used.

useDefaultSymbol

void useDefaultSymbol(boolean b)

isSuitableForShapeType

boolean isSuitableForShapeType(int shapeType)

draw

void draw(BufferedImage image,
        Graphics2D graphics2D,
        ViewPort viewPort,
        Cancellable cancel,
        double scale,
        Map queryParameters,
        ICoordTrans coordTrans,
        FeatureStore featureStore)
          throws LegendException

Draws the FeatureStore data using this legend simbology.

Parameters:

image - the base image to draw over

graphics2D - the Graphics2D to draw to

viewPort - the ViewPort to use

cancel - the Cancellable delegate object

scale - the scale of the view

queryParameters - the query parameters

coordTrans - the transformation coordinates to use for reprojection

featureStore - FeatureStore to load the data to draw from

Throws:

LegendException

        FeatureStore featureStore,
        FeatureQuery featureQuery)
          throws LegendException

Draws the FeatureStore data using this legend simbology.

Parameters:

image - the base image to draw over

graphics2D - the Graphics2D to draw to

viewPort - the ViewPort to use
