Overview of Package rschmidt.utils Release 1.1

by Roman Schmidt

This package provides useful utility classes. This code consists of implementations of ideas that have been around for ages, and is merely intended to save you the trouble of coding them.

The package mainly consists of implementations of a few utilities:

• Logging: Utilities used by the standard Java Logger.
• Tokenizer: Uses the standard Java StringTokenizer to tokenize given strings by a given separator.
• Compression: Uses the standard Java Deflator and Inflator to compresses and decompress data.
• Cloner: Clones any seriazable object and all seriazable member objects.
• Converter: Converts bytes to binary strings, to hexadecimal strings, and hexadecimal strings to bytes.

Installation

This package, currently declared as rschmidt.utils is available in zip format including a JAR file, binaries, source files, JavaDoc API documentation and an Apache ANT build file.

To use it, add the binaries or the jar file in your classpath and import them in your Java files:

import rschmidt.utils.*

Documentation

The documentation was produced by JavaDoc.

• Logging: Utilities used by the standard Java Logger.
• LogFormatter ... Formats a LogRecord into a plain text format, defined by a format pattern.
• LogFilter ... This Filter can be used to provide fine grain control over what is logged, beyond the control provided by log levels.
• FlushedStreamHandler ... Extends the default Java StreamHandler by flushing the stream after every published LogRecord.
• Tokenizer: Uses the standard Java StringTokenizer to tokenize given strings by a given separator.
• Compression: Uses the standard Java Deflator and Inflator to compresses and decompress data.
• Cloner: Clones any serializable object and all serializable member objects.
• Converter: Converts bytes to binary strings, to hexadecimal strings, and hexadecimal strings to bytes.

Notes

• All classes are released to the public domain under the GNU GPL and may be used for any purpose whatsoever without permission or acknowledgment.
• Most of the interfaces and classes contain usage notes and examples. I hope to add more. Please send suggestions to R.Schmidt@infosys.tuwien.ac.at
• These have been tested with Java^TM 2 Platform Standard Edition v1.4.1.
