Examples of com.mxgraph.io.vdx.mxVdxShape

com.mxgraph.io.vdx.mxVdxShape
This class is a wrapper for one Shape Element.
This class is responsible for retrieve all the properties of the shape and add it to the graph. If a property is not found in the shape element but it is an instance of a Master, the property is taken from the masterShape element. If the property is not found neither in the masterShape , and it has a reference to a stylesheet the property is taken from there.
