Metaprogramming With The Groovy Runtime - Part 1 of 2
summary
Covers concrete Groovy runtime metaprogramming: demonstrates the Meta Object Protocol (MOP), builds a mini-Expando with TDD (Spock) and shows setProperty/getProperty and methodMissing/setProperty/getProperty hooks handling made-up properties and dynamic method calls; shows closures with delegates to implement DSLs and how to add or replace methods on Java classes (String) at runtime. All demos run in the IDE with passing tests and live examples that actually execute the behaviors described.
