Defined in: lib/rss/rss.rb

Instance Method Summary

Utils - Included

#element_initialize_arguments?

This method is used inside of several different objects to determine if special behavior is needed in the constructor.
#get_file_and_line_from_caller

Returns an array of two elements: the filename where the calling method is located, and the line number where it is defined.
#h,
#html_escape

Takes a string s with some HTML in it, and escapes ‘&’, ‘“’, ‘<’ and ‘>’, by replacing them with the appropriate entities.
#new_with_value_if_need

If value is an instance of class klass, return it, else create a new instance of klass with value value.
#to_class_name

Given a name in a name_with_underscores or a name-with-dashes format, returns the CamelCase version of name.
