StringSearch

Home Page

Categories: Miscellaneous

Author: Johann Burkard

Latest version: 1.2
Added 2005-06-10

The Java language lacks string searching algorithms. The StringSearch library provides implementations of algorithms of the Boyer-Moore family and the Shift-Or (bit-parallel) family. These algorithms are easily five to ten times faster than the naive implementation found in java.lang.String.

JDRing

Home Page

Categories: Miscellaneous

Latest version: 2.0
Added 2006-03-20

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.

Latest version: 2.0
Added 2005-06-14

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.

JEF

Home Page

Categories: Frameworks, Miscellaneous

Latest version: 0.4.1
Added 2005-09-22

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.

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.

Java infrastructure software that allows you to scale your application to as many computers as needed, without expensive custom code or databases.
Terracotta is an open source clustering solution that provides transparent clustering and coordination services.

Features include:
- Heap-Level replication: selectively share object graphs across the cluster.
- Cross-JVM coordination.
- Large virtual heaps: manage heaps that are much bigger than what can be contained in a single JVM.
- Fine-grained changes: Terracotta does not use serialization, and therefore can push field-level changes to the cluster. This translates into better network efficiency for replication.
- Runtime management and control: view in real-time objects in the heap.
- No serialization: because Terracotta clusters at the JVM level, no serialization code is required.
- Cluster-wide locking semantics: distributed wait/notify and synchronized.

Jar Jar Links

- 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.
