Asm2class is a java assembly to class file compiler.

Asm2class is release under the terms of the GPL License. The current version of asm2class (0.1.2) is a beta version and allow generating class file from java assembly file that contains class definition, field definition, method definition and constructor definition.

This release support also abstract class, abstract method and native method definition.

Asm2class know more thatn 90% of the java assembly language. Asm2class can do dead code detection, uninitialized register detection.

jclassinfo reads java class files and provides information about the class, dependencies and more. It is a pure C implementantion.

Java::JCR::Lock is a Perl module that can load JCR lock extension wrappers.

SYNOPSIS

use Java::JCR::Lock

This loads the Perl classes mapped to the Java package named javax.jcr.lock.

Installation:

Installation can be a bit tricky because this library depends upon Inline::Java,
which didnt install without going through the process by hand. (I usually just
let CPAN do all the work.) You must first install Inline::Java.

Then, you must install libwww-perl, as I use that to download the Jar files. I
hope to remove this dependency in the future, but its there for now.

After installing both of those, you should be able to run:

perl Build.PL
./Build
./Build test
./Build install

I generally try to make my build scripts as standard as possible. If you prefer
using make, I have Module::Build distributing a makefile generator too:

perl Makefile.PL
make
make test
make install

Class::Inner is a perlish implementation of Java like inner classes.

SYNOPSIS

use Class::Inner;

my $object = Class::Inner->new(
parent => ParentClass,
methods => { method => sub { ... } }, },
constructor => new,
args => [@constructor_args],
);

Yet another implementation of an anonymous class with per object overrideable methods, but with the added attraction of sort of working dispatch to the parent classs method.

METHODS

new HASH

Takes a hash like argument list with the following keys.

parent

The name of the parent class. Note that you can only get single inheritance with this or SUPER wont work.

methods

A hash, keys are method names, values are CODEREFs.

constructor

The name of the constructor method. Defaults to new.

args

An anonymous array of arguments to pass to the constructor. Defaults to an empty list.

Returns an object in an anonymous class which inherits from the parent class. This anonymous class has a couple of extra methods:

SUPER

If you were to pass something like

$obj = Class::Inner->new(
parent => Parent,
methods => { method => sub { ...; $self->SUPER::method(@_) } },
);

then $self-gtSUPER::method almost certainly wouldnt do what you expect, so we provide the SUPER method which dispatches to the parent implementation of the current method. There seems to be no good way of getting the full SUPER:: functionality, but Im working on it.

DESTROY

Because Class::Inner works by creating a whole new class name for your object, it could potentially leak memory if you create a lot of them. So we add a DESTROY method that removes the class from the symbol table once its finished with.

If you need to override a parents DESTROY method, adding a call to Class::Inner::clean_symbol_table(ref $self) to it. Do it at the end of the method or your other method calls wont work.

clean_symbol_table

The helper subroutine that DESTROY uses to remove the class from the symbol table.

new_classname

Returns a name for the next anonymous class.

Parse::Java is a Perl module that acts like a parser for Java code.

SYNOPSIS

use Parse::Java;

my $ast = Parse::Java->parse_file(MyClass.java);

Parse::Java parses Java code into an Abstract Syntax Tree which can be used for many things like writing compilers and stuff.

As this module is currently under development it isnt yet able to parse much Java. Whats in the t/*.t basically works but not much else.

The lexer should also more or less work fine except expansion of unicode escapes uNNNN.

INTERFACE

This module uses an object-oriented interface.

CLASS METHODS

parse_file ( $path )

Parses the contents of the file $path. Returns an AST representing the code.

parse_string

Parses the source in $string. Returns an AST representing the code.

detokenize ( $ast )

Walks the AST and replaces all Parse::Java::Token-objects with their stringified value.

INSTANCE METHODS

_set_input ( $source )

Sets the input to the lexer.

_next_token

Returns a list with the next token from the stream and its value.

FaceRSS is a simple JavaServer Faces (JSF) component that allows you to display news from specified RSS url source in one configurable tag.

So, you can place your favorite news on your website in a very simple way. FaceRSS library uses rsslib4j and therefore supports RSS version 0.9x, 1.0, and 2.0 with Syndication and Dublin Core namespaces.

Usage:

copy the facerss.jar to your WEB-INF/lib folder and add to your build path.

Methods inherited from class java.lang.Object

equals, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait
