CompilationUnit (groovy 2.4.0 API)

org.codehaus.groovy.control.CompilationUnit

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.

  - public CompilationUnit()
    
    Initializes the CompilationUnit with defaults.
  - public CompilationUnit(GroovyClassLoader loader)
    
    Initializes the CompilationUnit with defaults except for class loader.
  - public CompilationUnit(CompilerConfiguration configuration)
    
    Initializes the CompilationUnit with no security considerations.
  - public CompilationUnit(CompilerConfiguration configuration, CodeSource security, GroovyClassLoader loader)
    
    Initializes the CompilationUnit with a CodeSource for controlling security stuff and a class loader for loading classes.
  - public CompilationUnit(CompilerConfiguration configuration, CodeSource security, GroovyClassLoader loader, GroovyClassLoader transformLoader)
    
    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 CompilationUnit.class.classLoader must be at last a parent to transformLoader. The other loader has no such constraint.
    Parameters:
    transformLoader - - the loader for transforms
    loader - - loader used to resolve classes against during compilation
    security - - security setting for the compilation
    configuration - - compilation configuration
- Method Detail

    Dequeues any source units add through addSource and resets the compiler phase to initialization.
    Note: this does not mean a file is recompiled. If a SourceUnit has already passed a phase it is skipped until a higher phase is reached.

    Returns:
    true if there was a queued source
  - public CompileUnit getAST()

    Sets a ClassgenCallback. You can have only one, and setting it to null removes any existing setting.

    Sets a ProgressCallback. You can have only one, and setting it to null removes any existing setting.
