Examples of org.uengine.kernel.Activity

org.uengine.kernel.Activity
This class plays the most important role in the uEngine ,which is composed of key attributes and methods of general behaviors, properties and callback messages of Activity Types. To understand uEngine's process model, you may need to understand 'Composite Pattern' (which is one of most well-known design pattern also used in java.io.File) first. That is, this Activity class and ComplexActivity has a self-contained relationship for easy-activity-type extension and easy-to-hold the block-based (structured) process model. @author Jinyoung Jang @see org.uengine.kernel.ComplexActivity
