CompilationUnit (Groovy 5.0.0-SNAPSHOT)

org.codehaus.groovy.control.CompilationUnit

```
public class CompilationUnit
extends ProcessingUnit
```
The CompilationUnit collects all compilation data as it is generated by the compiler system. You can use this object to add additional source units to the compilation, or force the compilation to be run again (to affect only the deltas).
You can also add PhaseOperations to this compilation using the addPhaseOperation method. This is commonly used when you want to wire a new AST Transformation into the compilation.

    Initializes the CompilationUnit with a CodeSource for controlling security stuff, a class loader for loading classes, and a class loader for loading AST transformations.
    Note: The transform loader must be able to load compiler classes. That means classLoader must be at last a parent to transformLoader. The other loader has no such constraint.

    transformLoader - - the loader for transforms
    loader - - loader used to resolve classes against during compilation
    codeSource - - security setting for the compilation
    configuration - - compilation configuration

  - protected boolean dequeued()
    
    Dequeues any source units added through addSource and resets the compiler phase to initialization.
