docs: Matches an AST node that represents a method declaration, based on the list of
  variableMatchers. Applies the variableMatcher at index n to the parameter at index n and
  returns true iff they all match. Returns false if the number of variableMatchers provided does
  not match the number of parameters.
  
  <p>If you pass no variableMatchers, this will match methods with no parameters.
  
  @param variableMatcher an array of matchers to apply to the parameters of the method
