## [Java] Class CompileUnit

- org.codehaus.groovy.ast.CompileUnit

- Represents the entire contents of a compilation step which consists of one or more ModuleNode instances. There's one instance of this that's shared by all modules and classes compiled during a single invocation of the compiler.

  It's attached to MethodNodes and ClassNodes and is used to find fully qualified names of classes, resolve imports, and that sort of thing.

  - ### Method Detail

    - #### public void addClass(ClassNode node)

      Adds a class to the unit.

    - #### public void addClassNodeToCompile(ClassNode node, org.codehaus.groovy.control.SourceUnit location)

      this method actually does not compile a class. It's only a marker that this type has to be compiled by the CompilationUnit at the end of a parse step no node should be be left.

    - #### public void addGeneratedInnerClass(InnerClassNode icn)

    - #### public void addModule(ModuleNode node)

    - #### public ClassNode getClass(String name)

      Returns:
        the ClassNode for the given qualified name or returns null if the name does not exist in the current compilation unit (ignoring the .class files on the classpath)

    - #### public GroovyClassLoader getClassLoader()

    - #### public List getClasses()

      Returns:
        a list of all the classes in each module in the compilation unit

    - #### public CodeSource getCodeSource()

    - #### public CompilerConfiguration getConfig()

    - #### public Map<String, InnerClassNode> getGeneratedInnerClasses()

    - #### public ListHashMap getMetaDataMap()

    - #### public List<ModuleNode> getModules()

    - #### <T> public T getNodeMetaData(Object key)

      Gets the node meta data for the provided key.

      Parameters:
        `key` - - the meta data key
      Returns:
        the node meta data value for this key

    - #### public Map<?, ?> getNodeMetaData()

      Returns an unmodifiable view of the current node metadata.

      Returns:
        the node metadata. Always not null.

    - #### public org.codehaus.groovy.control.SourceUnit getScriptSourceLocation(String className)

      throws:
        GroovyBugError if key is null
      Parameters:
        `key` - - the meta data key
        `value` - - the meta data value
      Returns:
        the old node meta data value for this key

    - #### public void removeNodeMetaData(Object key)

      Removes a node meta data entry.

      throws:
