The tool apt
, annotation processing tool, includes a set of
new reflective APIs and supporting infrastructure to process program
annotations. The apt
reflective APIs provide a build-time,
source-based, read-only view of program structure. These reflective
APIs are designed to cleanly model the
programming language's type system
after the addition of generics. First, apt
processors that can produce new source code and other files. Next,
can cause compilation of both original and generated
source files, easing development. The reflective APIs and other APIs
used to interact with the tool are subpackages of
A fuller discussion of how the tool operates as well as
instructions for developing with apt are in
Getting Started with apt.
apt specific options
- -s dir
- Specify the directory root under which processor-generated source
files will be placed; files are placed in subdirectories based
on package namespace.
- Do not compile source files to class files.
- Print out textual representation of specified types; perform no
annotation processing or compilation.
- Options to pass to annotation processors -- these are not
interpreted by apt directly, but are
made available for use by
- -factorypath path
- Specify where to find annotation processor factories; if this
option is used, the classpath is not searched for factories.
- -factory classname
- Name of annotation processor factory to use; bypasses default discovery process
Options shared with javac
- -d dir
- Specify where to place processor and javac generated class files
- -cp path or -classpath path
- Specify where to find user class files and annotation processor
factories. If -factorypath is given, the classpath is not
searched for factories.
Consult the javac(1) man page for information on javac
tool and its associated APIs may be changed or superseded in
future j2se releases.
