## Class AptCompilerAdapter

- java.lang.Object
- - org.apache.tools.ant.taskdefs.compilers.DefaultCompilerAdapter
  - - org.apache.tools.ant.taskdefs.compilers.AptCompilerAdapter

- All Implemented Interfaces:
    CompilerAdapter, CompilerAdapterExtension

      public class AptCompilerAdapter
      extends DefaultCompilerAdapter

  The implementation of the apt compiler for JDK 1.5

  As usual, the low level entry points for Java tools are neither documented or stable; this entry point may change from that of 1.5.0_01-b08 without any warning at all. The IDE decompile of the tool entry points is as follows:

       public class Main {
       public Main() ;

       public static transient void main(String... strings) ;

       public static transient int process(String... strings);

       public static transient int process(PrintWriter printWriter,
            String... strings) ;
       public static transient int process(
            AnnotationProcessorFactory annotationProcessorFactory,
            String... strings) ;

       public static transient int process(
            AnnotationProcessorFactory annotationProcessorFactory,
            PrintWriter printWriter,
            String... strings);
       private static transient int processing(
            AnnotationProcessorFactory annotationProcessorFactory,
            PrintWriter printWriter,
            String... strings) ;
       }

  This Adapter is designed to run Apt in-JVM, an option that is not actually exposed to end-users, because it was too brittle during beta testing; classpath problems being the core issue.
  Since:
    Ant 1.7
