Class Walker

  • public final class Walker
extends java.lang.Object
    Walks connected shapes within a shape index.

    Any shape that is connected to another shape is "walked". A single shape can have multiple relationships to the same shape. For example, a resource can have both a "get" and a "child" relationship to an operation; however, the referenced operation will appear only once in the walker output.

    Only shapes form a connected graph. Relationships created by traits are not traversed by the walker.
