DirtyCheckingTransformer (Grace Data

org.grails.compiler.gorm.DirtyCheckingTransformer

All Implemented Interfaces and Traits:

CompilationUnitAware
```
@CompileStatic
class DirtyCheckingTransformer
extends Object
implements CompilationUnitAware
```
Transforms a domain class making it possible for the domain class to take responsibility of tracking changes to itself, thus removing the responsibility from the ORM system which would have to maintain parallel state and compare the state of the domain class to the stored state. With this transformation the storage of the state is not necessary as the state is kept in the domain class itself.
