  +--suvi.api.alg.attr.GraphLayoutAttrTransformer

All Implemented Interfaces:

FlowTrendConstants

public abstract class GraphLayoutAttrTransformer

extends java.lang.Object

implements FlowTrendConstants

Canonicalization transformation function for graph layout attributes. Each graph layout attribute interface, that contains geometry information that needs to be canonicalized, must contain a static constant field named TRANSFORMER that implements this class.
