ph-commons

Java 1.8+ Library with tons of utility classes required in most of ph-* projects.

Version 6.x contains major changes and more or less all other projects were released to reflect the changes of 6.x. Version 7 does not exist. Version 8.x was re-designed to best work with JDK 8. So please ensure to not mix 5.x, 6.x and 8x. versions of ph-commons!

This project was the following modules:

• ph-charset - support for additional character sets (e.g. UTF-7)
• ph-commons - the most common base library stuff
• ph-datetime - extension library for handling Java date and time special cases
• ph-graph - generic graph library with directed and undirected graphs
• ph-jaxb - the JAXB utility classes building upon ph-commons and ph-xml
• ph-json - a generic simple JSON reader, visitor and writer
• ph-less-commons - previously contained in ph-commons not really used but I was afraid to dump it :)
• ph-matrix - a simple library for handling matrix data structures and operations
• ph-security - security related topics like key store handling, message digests etc
• ph-settings - a small library for handling configuration files in an easy way
• ph-tree - generic tree structures and tree singleton base classes
• ph-xml - everything to read and write XML, including "MicroDOM" my personal minimum XML representation shipping with its own serializer.
