Method: CodeNode::DSL::GraphDefiner#ignore

Defined in:

lib/code_node/dsl/graph_definer.rb

#ignore(name = nil) {|node| ... } ⇒ nil

Specify an ignore rule for the graph. Nodes matching the ignore rule will not be included in the graph. Ignore rules can be given in one of three ways,

• String provide a fully qualified path which will have to match IR::Node::QueryMethods#path exactly

• Regexp provide a pattern that will be tested against the IR::Node::QueryMethods#path

• Proc provide a block. If the block returns true the node will be ignored

Examples:

CodeNode.graph 'my_graph' do |g|

  # Using a full path
  g.ignore 'Foo::Bar::Car'

  # Using a regular expression
  g.ignore /ClassMethods$/

  # Using a block
  g.ignore do |node|
    node.inherits_from? 'Exception'
  end
end

Yield Parameters:

• node (IR::Node::QueryMethods) —

  if provided, return true to ignore the node

  end
