    • instance

      public static JavacTask instance​(ProcessingEnvironment processingEnvironment)
      Returns the JavacTask for a ProcessingEnvironment. If the compiler is being invoked using a CompilationTask, then that task will be returned.
      Parameters:
      processingEnvironment - the processing environment
      Returns:
      the JavacTask for a ProcessingEnvironment

    • parse

      public abstract Iterable<? extends CompilationUnitTree> parse() throws IOException
      Parses the specified files returning a list of abstract syntax trees.
      Returns:
      a list of abstract syntax trees
      Throws:
      IOException - if an unhandled I/O error occurred in the compiler.
      IllegalStateException - if the operation cannot be performed at this time.

    • analyze

      public abstract Iterable<? extends Element> analyze() throws IOException
      Completes all analysis.
      Returns:
      a list of elements that were analyzed
      Throws:
      IOException - if an unhandled I/O error occurred in the compiler.
      IllegalStateException - if the operation cannot be performed at this time.

    • generate

      public abstract Iterable<? extends JavaFileObject> generate() throws IOException
      Generates code.
      Returns:
      a list of files that were generated
      Throws:
      IOException - if an unhandled I/O error occurred in the compiler.
      IllegalStateException - if the operation cannot be performed at this time.

    • setTaskListener

      public abstract void setTaskListener​(TaskListener taskListener)
      Sets a specified listener to receive notification of events describing the progress of this compilation task. If another listener is receiving notifications as a result of a prior call of this method, then that listener will no longer receive notifications. Informally, this method is equivalent to calling removeTaskListener for any listener that has been previously set, followed by addTaskListener for the new listener.
      Parameters:
      taskListener - the task listener
      Throws:
      IllegalStateException - if the specified listener has already been added.

    • addTaskListener

      public abstract void addTaskListener​(TaskListener taskListener)
      Adds a specified listener so that it receives notification of events describing the progress of this compilation task. This method may be called at any time before or during the compilation.
      Parameters:
      taskListener - the task listener
      Throws:
      IllegalStateException - if the specified listener has already been added.
      Since:
      1.8

    • removeTaskListener

      public abstract void removeTaskListener​(TaskListener taskListener)
      Removes the specified listener so that it no longer receives notification of events describing the progress of this compilation task. This method may be called at any time before or during the compilation.
      Parameters:
      taskListener - the task listener
      Since:
      1.8

    • setParameterNameProvider

      public void setParameterNameProvider​(ParameterNameProvider provider)
      Sets the specified ParameterNameProvider. It may be used when VariableElement.getSimpleName() is called for a method parameter for which an authoritative name is not found. The given ParameterNameProvider may infer a user-friendly name for the method parameter. Setting a new ParameterNameProvider will clear any previously set ParameterNameProvider, which won't be queried any more. When no ParameterNameProvider is set, or when it returns null from ParameterNameProvider.getParameterName(javax.lang.model.element.VariableElement), an automatically synthesized name is returned from VariableElement.getSimpleName().
      Implementation Requirements:
      The default implementation of this method does nothing.
      Parameters:
      provider - the provider.

    • getTypeMirror

      public abstract TypeMirror getTypeMirror​(Iterable<? extends Tree> path)
      Returns a type mirror of the tree node determined by the specified path. This method has been superceded by methods on Trees.
      Parameters:
      path - the path
      Returns:
      the type mirror

      Trees.getTypeMirror(com.sun.source.util.TreePath)

    • getElements

      public abstract Elements getElements()
      Returns a utility object for dealing with program elements.
      Returns:
      a utility object for dealing with program elements

    • getTypes

      public abstract Types getTypes()
      Returns a utility object for dealing with type mirrors.
      Returns:
      the utility object for dealing with type mirrors
