Class BuckJavacTask

java.lang.Object

com.sun.source.util.JavacTask

com.facebook.buck.jvm.java.plugin.adapter.BuckJavacTask

All Implemented Interfaces:

Callable<Boolean>, JavaCompiler.CompilationTask

Direct Known Subclasses:

FrontendOnlyJavacTask

public class BuckJavacTask
extends com.sun.source.util.JavacTask

Extends JavacTask with functionality that is useful for Buck:

• Exposes the enter method from JavacTaskImpl
• Pre-javac-8 support for addTaskListener/removeTaskListener
• Wraps Elements with some extended functionality

parse

public Iterable<? extends com.sun.source.tree.CompilationUnitTree> parse()
                                                                  throws IOException

Throws:

IOException

enter

public Iterable<? extends Element> enter()
                                  throws IOException

Throws:

IOException

setTaskListener

public void setTaskListener(com.sun.source.util.TaskListener taskListener)

Sets a TaskListener. Like JavacTask's implementation of this method, the listener does not replace listeners added with addTaskListener(TaskListener). Instead, it replaces only the listener provided in the previous call to this method, if any.

Presumably this behavior was to enable Plugins to work properly with build systems that were written when only a single TaskListener was supported at a time.

addTaskListener

public void addTaskListener(com.sun.source.util.TaskListener taskListener)

removeTaskListener

public void removeTaskListener(com.sun.source.util.TaskListener taskListener)

getElements

public ElementsExtended getElements()

addPlugin

public void addPlugin(BuckJavacPlugin plugin,
                      String... args)

addPostEnterCallback

public void addPostEnterCallback(java.util.function.Consumer<Set<Element>> callback)

getTrees

public com.sun.source.util.Trees getTrees()

started

protected void started(com.sun.source.util.TaskEvent e)

finished

protected void finished(com.sun.source.util.TaskEvent e)

onPostEnter

protected void onPostEnter(Set<Element> topLevelElements)
