Overview

Note:

This exception will be thrown if and only if a Vertex is added to a DependencyGraph that has a DependencyGraph::Vertex#path_to? an existing DependencyGraph::Vertex

An error caused by attempting to fulfil a dependency that was circular

Instance Attribute Summary

• #dependencies ⇒ Object readonly

  Set<Object>

  the dependencies responsible for causing the error.

Instance Method Summary

• #initialize(vertices) ⇒ CircularDependencyError constructor

  Initializes a new error with the given circular vertices.

Constructor Details

#initialize(vertices) ⇒ CircularDependencyError

Initializes a new error with the given circular vertices.

Parameters:

• vertices (Array<DependencyGraph::Vertex>) —

  the vertices in the dependency that caused the error

def initialize(vertices)
  super "There is a circular dependency between #{vertices.map(&:name).join(' and ')}"
