Groovy - Decorator Pattern
The Decorator Pattern provides a mechanism to embellish the behaviour of an object without changing its essential interface. A decorated object should be able to be substituted wherever the original (non-decorated) object was expected. Decoration typically does not involve modifying the source code of the original object and decorators should be able to be combined in flexible ways to produce obje
Groovy - Using the Delegating Meta Class
This is an example of how to replace a MetaClass to adjust the default behavior. Each groovy object has a metaClass that is used to manage the dynamic nature of the language. This class intercepts calls to groovy objects to ensure that the appropriate grooviness can be added. For example, when an object is constructed, the MetaClass's invokeConstructor()is called. One feature of the invokeConstru
Groovy - Design Patterns with Groovy
Using design patterns with Java is a well-established topic. Design patterns also apply to Groovy: some patterns carry over directly (and can make use of normal Groovy syntax improvements for greater readability) some patterns are no longer required because they are built right into the language or because Groovy supports a better way of achieving the intent of the pattern some patterns that have

Groovy Remote Control
What is Groovy Remote Control? Groovy remote control is a library for executing closures defined in one Groovy application to be executed in a different (possible remote) Groovy application. The current version is 0.1. What is it good for? The original driver for developing this library was to assist in functionally testing Grails applications (the plugin for Grails can be found here). Its use the

Groovy - Unit Testing
The Groovy Advantage Groovy simplifies JUnit testing, making it more Groovy, in several ways, including: JUnit is built into the groovy runtime, so you can script JUnit tests for your Groovy and Java classes using Groovy syntax. Groovy provides many additional JUnit assertion statements (see below) Groovy unit tests are easily scriptable with Ant / Maven (see below) Groovy provides Groovy Mocks Se
Groovy - ConfigSlurper
ConfigSlurper is a utility class within Groovy for writing properties file like scripts for performing configuration. Unlike regular Java properties files ConfigSlurper scripts support native Java types and are structured like a tree. Below is an example of how you could configure Log4j with a ConfigSlurper script: log4j.appender.stdout = "org.apache.log4j.ConsoleAppender" log4j.appender."stdout.l
