Method Detail

getShape

public Shape getShape(Graphics2D graphics,
                      Expression symbolUrl,
                      Feature feature)

Return a shape with the given url.

Specified by:

getShape in interface MarkFactory

symbolUrl - the expression that will return the symbol name. Once evaluated the expression should return something like plainName or like protocol://path. See the actual implementations for details on the kind of supported name.

feature - The feature that will be used to evaluate the symbolURL expression (or to extract data from it, think complex attributes, in that case a visit to the expression and some direct attribute value extraction might be needed instead)
