getShape
Description copied from interface:MarkFactory
Turns the specified URL into an Shape, eventually using the Feature attributes to evaluate the expression, or returnsnull
if the factory cannot evaluate this symbolUrl.The returned Shape must not exceed the [-0.5, -0.5, 0.5, 0.5] bounds (will be rescaled according to the
parameter given in graphics on the fly - Specified by:
getShape
in interfaceMarkFactory
symbolUrl
- the expression that will return the symbol name. Once evaluated the expression should return something likeplainName
or likeprotocol://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)- Throws:
Exception
