A toolbox of language extensions and utilities for JVM-based languages, like Java. Supports Java 11 and later.

This was forked from Elder Research commons-jvm while it was Open Source/MIT licensed.

See Compassion Maven Parent for information on how to work with Maven at Compassion.

This sends the following transitive dependencies:

• Apache Commons Lang and Commons Text
• jOOλ
• Guava
• Jackson with YAML support
• Log4j2

Some of the utilities in this project include:

• Config, YAMLConfig, and EnvironmentTree: Powerful configuration that supports a configuration bean via YAML (or any other supported Jackson format) with environment (environment variable and/or system property) overrides.
• DaemonWorker: An easy to use wrapper around a daemon thread and a blocking queue for multithreaded, queueable tasks.
• @Documentation: Annotation to facilitate code generation and documentation of system components that can be reflected at runtime
• NumberExtractor and DateExtractor: General-purpose/robust number and date parser/extractor that uses all localized formats available to the JVM to extract values from text.
• IteratorCloseable, IteratorMultithreaded, and IteratorWithSize: Variants on the standard Iterator pattern offering deterministic progress, closeability, and parallelism.
• LambdaUtils: Utilities for using Java 8 lambdas
• ReflectionUtils: Wrapper around the Java reflection APIs, simplifying their use and absorbing exceptions.
• StatusMonitor/StatusListener: "Transactional" status API for long-running tasks. You can set the task state, progress, or message in atomic operations continually, but listeners will only be notified at fixed time intervals (or when certain state changes regardless of time). You can poll a status monitor to know if the user canceled the task.
• StopWatch: Enhanced/improved version of Apache's stop watch functionality
• StringMatcher: Utility for programmatically matching strings using starts with, ends with, contains, equals, regular expressions, and ignore case.
• UnicodeChars: Constant declarations of most unicode characters
