Compiler Package Overview
This table shows the packages that make up the compiler. Except
as noted, all packages are in
com.sun.tools.javac.*.

Official API
- javax.annotation.processing
- Facilities for
declaring annotation processors and for allowing annotation
processors to communicate with an annotation processing tool
environment.
- javax.lang.model and subpackages
- Classes and
hierarchies of packages used to model the Java programming
language.
- javax.tools
- Provides interfaces
for tools which can be invoked from a program, for example,
compilers.
Supported API
- com.sun.source
and subpackages
- Representation of
the compiler syntax trees.
- (top level)
- The javac main
program and command-line entry point provides supported API for
very simple invocation of the compiler.
Internal API and implementation classes
- api
- Implementation of
JavaCompiler and other API in
javax.tools.
- code
- Representation of
the semantic elements of a Java program, such as symbols, scopes
and types, implementing API in
javax.lang.model.*.
- comp
- Primary processing
phases for the compiler, such as attribution, flow analysis,
"desugaring" and erasure.
- file
- Access to the
native file system, including the implementation of
javax.tools.StandardFileManager.
- file
- Access to the
native file system using the java.nio.file API, including
JavacPathFileManager.
- jvm
- Classes for reading
and writing class files, and the code generation phase of the
compiler.
- main
- Main driver code
for any compilation. It provides option decoding and sequences
through the various steps for compilation.
- model
- Additional
implementation classes for
javax.lang.model.*.
- parser
- Read Java source
code to generate syntax trees.
- processing
- Implementation
classes for annotation processing API defined in
javax.annotation.processing.*.
- resources
- Resource files for
localized messages and version info.
- tree
- Representation and
utility classes for the compiler's syntax trees, implementing API
in
com.sun.source.*.
- util
- Basic utility
classes, including support for reporting diagnostics.
