Package software.amazon.smithy.model.shapes

Class Shape

java.lang.Object
software.amazon.smithy.model.shapes.Shape
All Implemented Interfaces:
Comparable<Shape>, FromSourceLocation, ToShapeId, Tagged
Direct Known Subclasses:
CollectionShape, EntityShape, MapShape, MemberShape, OperationShape, SimpleShape, StructureShape, UnionShape
public abstract class Shape extends Object implements FromSourceLocation, Tagged, ToShapeId, Comparable<Shape>
A Shape defines a model component.

A Shape may have an arbitrary number of typed traits attached to it, allowing additional information to be associated with the shape.

Shape does implement Comparable, but comparisons are based solely on the ShapeId of the shape. This assumes that shapes are being compared in the context of a Model that forbids shape ID conflicts.
