Inherits:
EntityMatcher show all
Defined in:
lib/rewrite/by_example/symbol_entity.rb

Overview

Matches a specific symbol: SymbolEntity.new(:foo) matches :foo.

Note that this is not the same thing as matching the use of a symbol in Ruby code, because a literal symbol in Ruby is actually represented as:

s(:lit, :foo)
