Method Detail

instance

public static JavacTask instance(ProcessingEnvironment processingEnvironment)

Get 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

Since:

1.8

parse

public abstract Iterable<? extends CompilationUnitTree> parse()
                                                       throws IOException

Parse 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

Complete 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

Generate 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)

The specified listener will 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.

Throws:

IllegalStateException - if the specified listener has already been added.

addTaskListener

public abstract void addTaskListener(TaskListener taskListener)

The specified listener will receive notification of events describing the progress of this compilation task. This method may be called at any time before or during the compilation.

Throws:

IllegalStateException - if the specified listener has already been added.

Since:

1.8

removeTaskListener

public abstract void removeTaskListener(TaskListener taskListener)

The specified listener will no longer receive notification of events describing the progress of this compilation task. This method may be called at any time before or during the compilation.

Since:

1.8

getTypeMirror

public abstract TypeMirror getTypeMirror(Iterable<? extends Tree> path)

Get a type mirror of the tree node determined by the specified path. This method has been superceded by methods on Trees.

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

getElements

public abstract Elements getElements()

Get a utility object for dealing with program elements.

getTypes

public abstract Types getTypes()

Get a utility object for dealing with type mirrors.
