fastutil

Wed, 25 May 2005 06:10:06 GMT

fastutil extends the Java Collections Framework by providing type-specific maps, sets, lists and priority queues with a small memory footprint and fast access and insertion; it also includes a fast I/O API for binary and text files. The classes implement their standard counterpart interface (e.g., Map for maps) and can be plugged into existing code. Moreover, they provide additional features (such as bidirectional iterators) that are not available in the standard classes.

Commons Configuration provides typed access to single, and multi-valued configuration parameters as demonstrated by the following code:
  Double double = config.getDouble("number");
  Integer integer = config.getInteger("number");

Configuration parameters may be loaded from the following sources:
- Properties files
- XML documents
- Property list files (.plist)
- JNDI
- JDBC Datasource
- System properties
- Applet parameters
- Servlet parameters

Different configuration sources can be mixed using a ConfigurationFactory and a CompositeConfiguration. Additional sources of configuration parameters can be created by using custom configuration objects. This customization can be achieved by extending AbstractConfiguration or AbstractFileConfiguration.

GOLD Parser

Tue, 15 Mar 2005 21:19:58 GMT

Parsing system that you can use to develop your own programming languages, scripting languages and interpreters.

The GOLD Parser strives to be a development tool that can be used with numerous programming languages and on multiple platforms.
Unlike common compiler-compilers, the GOLD Parser does not require you to embed your source code directly into the grammar. Instead, the application analyzes the grammar and then saves the parse tables to a separate file. This file can be subsequently loaded by the actual parser engine and used.

Since the parse tables are programming language independent, the parser engine can be, and has been, implemented in different programming languages. As a result, the GOLD Parser supports multiple programming languages.
Supported languages include: ANSI C, C#, C++, Delphi, Java, Python, Visual Basic 6, Visual Basic .NET, and wxWidgets.

JDRing

Mon, 20 Mar 2006 17:29:19 GMT

Scheduling library that supports ringing alarms at specified intervals, as one-time events, or on complex schedules with full cron-like control.

Features include:
- Alarms are added to and removed from the schedule in code. No file formats or XML schemas to learn.
- You can optionally specify a name for each alarm; this lets you use a single listener for multiple alarms.
- Alarms can be rung at a fixed interval, or at a single fixed date, or on a cron-based flexible schedule.
- With cron-style scheduling, you can provide a list of minutes, hours, days of the month, days of the week, and months (or "all" for any of these), and the alarm will ring on every match.
- Counting standards are consistent with the java.utils.Calendar class, so minutes range from 0 to 59, hours from 0 to 23, days of the week from 1 (Sunday) to 7, and days of the month from 1 to 31 (depending on the month).
- Alarms by default are rung (listeners are notified) within a single alarm thread, so a long-running alarm will delay following alarms until it completes. This may be what you want, because alarm tasks may be dependent on previous ones. If not, any alarm may be flagged to ring in a separate thread, so that it will not delay the other alarms.

Dozer

Tue, 20 Sep 2005 09:15:22 GMT

Java Bean to Java Bean mapper that recursively copies data from one object to another. Typically, these Java Beans will be of different complex types.

Dozer supports simple property mapping, complex type mapping, bi-directional mapping, implicit-explicit mapping, as well as recursive mapping. This includes mapping collection attributes that also need mapping at the element level.
The mapper is used any time you need to take one type of Java Bean and map it to another type of Java Bean. Most field mapping can be done automatically by Dozer using reflection, but any custom mapping can be predescribed in XML format. Mapping is bi-directional so only one relationship between classes needs defining. If any property names on both objects are the same you do not even need to do any explicit property mapping for these fields.

Features include:
- Context based mapping
- Collection and Array mapping handling Lists, Sets, Arrays and allowing for class type hints
- Support for custom converters
- Custom bean factories for beans that do not follow the JavaBean specification
- Inheritance mapping including abstract classes and interfaces

PooliT

Tue, 14 Jun 2005 19:44:24 GMT

PooliT is a Java object pooling library capable of pooling any type of Java object. Pooling objects can increase program performance and avoid the overhead of object creation. Good candidates for pooling are classes that have costly instantiation routines, like database connections or sockets. By conserving and re-using these objects, you save processor cycles creating new objects and also alleviate the garbage collector from having to reclaim them up after use.

Executor

Tue, 27 Sep 2005 12:13:35 GMT

Package your Java application as a jar, and Executor will turn the jar into a Windows exe file, indistinguishable from a native application. Simply double-clicking the exe file will invoke the Java Runtime Environment and launch your application.

This allows you to distribute your Java application as a genuine Win32 binary executable. Your users will never need to run an ugly batch file to run your application. You will not have to distribute any temp or config files along with your executable. You will never need to learn JNI and have a C compiler to make a launcher for your application. You will save the hours of effort needed for writing a native launcher with this one tool.

Commons Launcher

Thu, 30 Jun 2005 08:12:59 GMT

Commons-launcher eliminates the need for a batch or shell script to launch a Java class. Some situations where elimination of a batch or shell script may be desirable are:
* You want to avoid having to determining where certain application paths are e.g. your application's home directory, etc. Determining this dynamically in a Windows batch scripts is very tricky on some versions of Windows or when softlinks are used on Unix platforms.
* You want to avoid having to handle native file and path separators or native path quoting issues.
* You need to enforce certain system properties e.g. java.endorsed.dirs when running with JDK 1.4.
* You want to allow users to pass in custom JVM arguments or system properties without having to parse and reorder arguments in your script. This can be tricky and/or messy in batch and shell scripts.
* You want to bootstrap system properties from a configuration file instead hard-coding them in your batch and shell scripts.
* You want to provide localized error messages which is very tricky to do in batch and shell scripts.

Shoal

Mon, 20 Nov 2006 19:16:17 GMT

Java-based clustering framework that provides infrastructure to build fault tolerance, reliability and availability.
The framework can be plugged into any product needing clustering and related distributed systems capabilities without tightly binding to a specific communications infrastructure.
The framework can be plugged in as an in-process component.
The framework offers two broad categories of public APIs:
- a Client API that allows in-process client components to be notified of cluster events and to send and receive messages to/from the group or individual members.
- a Group Communication Provider SPI that provides for integration of any group communication service provider technologies such as JXTA, JGroups, etc.

Shoal's default Group Communication Provider is JXTA given its strong credentials in the areas of security, ability to cross firewalls, virtualized networking, and several other strong group membership and communication features.

JEF

Thu, 22 Sep 2005 06:45:10 GMT

JEF, acronym for Java Evolutionary Framework, is a project aimed to both define and implement a genetic programming framework for the Java programming language.
JEF has been conceived as divided into three subprojects, namely: Dna, Jef and JXTA-Jef :

Dna: this is the basic building block for the JEF Proj since it provides a framework for dynamically manipulating Java class files. Amongst all the possibilities, this package allows developers to obtain object oriented Java class files representations, modify them according to their own needs up to the bytecode level (thus removing, adding or modifying the bytecode of already existing methods), add brand new methods to already existing classes, or even programmatically create new classes completely from scratch, validate newly created class files according to the constraints imposed by the Official Java Class File Specification, all by means of an easy to use/understand and well defined API characterized by a rapid learning curve.

Jef: the Jef subproject is meant to define the interfaces as well as some basic implementations of all those classes involved in the process of mixing two Java class files in order to generate a potentially brand new implementation, according to a customizable logic. This subproject is aimed to provide both demonstrative Mixer implementations and implementations useful to be deployed either directly or to be used as starting point for customized Mixer implementations. In the latter case developers will be berived of the burden of taking care of how some complex functionalities should be implemented, relying upon well tested and working implementations.

JXTA-Jef: deploying the Jef-Dna framework over a number of somehow interconnected computing-capable nodes, will enable us to let heterogeneous Java class files (i.e. mobile agents, teleo-reactive agents, etc.) move from one node to another, and potentially evolve with a really low degree of human interaction. This subproject is therefore necessary for building a decentralized (P2P - peer to peer) overlay network gathering Jef-capable nodes.

Jar Jar Links

Sun, 09 Sep 2007 22:15:50 GMT

Utility for repackaging Java libraries and embed them into your own distribution. This is useful for two reasons:
- You can ship a single jar file with no external dependencies.
- You can avoid problems where your library depends on a specific version of a library, which may conflict with the dependencies of another library.

How does it work?

Jar Jar Links includes an Ant task that extends the built-in jar task. The normal zipfileset element is used to embed jar files. A new rule element is added which uses wildcards patterns to rename the embedded class files. Bytecode transformation (via ASM) is used to change references to the renamed classes, and special handling is provided for moving resource files and transforming string literals.

Source Code Search Engine

Thu, 22 Oct 2009 11:07:55 GMT

Source code search engine.
Provides an interactive interface enabling one to search across a large source code base, using the language structure of each of the languages providing more precise answers than simple string searches can produce. For any query, the Search Engine offers a list of matches with surrounding context; the use can select a specific match and immediately inspect the source file.

Features include:
- Interactive search and inspection of source code
- Search across millions of lines of code, tens of thousands of source code files
- Query in terms of language lexical constructs such as identifiers, numbers, operators, string literals or comments to minimize false positives
- Generic queries can match identifiers or string literals across multiple programming languages
- Complex queries can match complex statements
- Queries can have patterns (or regular expressions) on character strings
- Numbers can compared to values or ranges
- Language elements are normalized so escape conventions do not confound searches
- Searches ignore language-specific intervening whitespace, linebreaks and comments, providing more accurate answers
- Optional GREP-like string (regular expression) search
- Scrollable list of search hits with context
- Can handle many computer languages (Java, C#, C++, etc.)
- Translates arbitrary characters sets into a uniform representation for indexing and display
