Class: PortableObjectTemplate

Inherits:
ObjectTemplate show all
Defined in:
lib/object-template.rb

Overview

Template specified by array or hash in a portable format composed of strings, numbers, booleans, arrays, and hashes. Special entry values correspond to wildcards and matchers of several kinds. See the unit tests for examples.

The objects matched include anything constructed out of numbers, booleans, including null, and strings using hashes and arrays. In other words, objects that can be serialized with json or msgpack.
