Defined in:

Overview

DependencySetGraph - extension of graph structure back by DependencySet

  • Extends our graph data structure

  • Overrides ‘#merge!` to merge both keys and set values

Examples:

Merge


dep1 # => { a: #<DependencyGraphSet: {1,2}> }
dep2 # => { a: #<DependencyGraphSet: {2,3}> }
dep1.merge(dep2) # => { a: #<DependencyGraphSet: {1,2,3}> }

Instance Method Details

#change_owner(new_owner:, &blk) ⇒ self

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Replace the owner of a certain set in the graph

Parameters:

  • new_owner: (Dependency::Base) —

    dependency key that will replace another

  • &blk (#call) —

    block used to detect owner to replace

Returns:

  • (self) —

    self with new owner

#merge!(*args) ⇒ DependencySetGraph

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Merge two dependency set graphs

Passes a block to ‘Hash#merge!` then instructs how two sets from different dependency graphs should be joined

Returns:
