1 module Context |

3 # This class is used to specify the namespace for a symbol |
4 # according to a priority list. When you create the Bridge |
5 # you initialize it either with a single module name, or an |
6 # array of module names. Calling "bridge.symbol" will return |
7 # the class in desired namespace (or nil if it doesn't exist) |
8 # If the Bridge was initialized with an array, it will pick |
9 # the first namespace that evaluates the symbol into something |
10 # that actually exists. |
