Class Method Summary (collapse)

• + (Object) Array(object)

  Ruby’s treatment of Strings as Enumerables is heavily annoying.

• + (Object) camel_case(string)

  Convert a string to camel case.

• + (Object) deep_merge(left, right)

  Perform a deep merge of hashes, returning the result as a new hash.

• + (Object) deep_merge!(left, right)

  Perform a deep merge of the right hash into the left hash.

• + (Object) extract_options_from(args)
• + (Object) format_float(f, digits)

  When generating boosts, Solr requires that the values be in standard (not scientific) notation.

• + (Object) full_const_get(string)

  Get a constant from a fully qualified name.

• + (Object) instance_eval_or_call(object, &block)

  Evaluate the given proc in the context of the given object if the block’s arity is non-positive, or by passing the given object as an argument if it is negative.

• + (Object) snake_case(string)

  Convert a string to snake case.

• + (Object) superclasses_for(clazz)
