This library contains basic Java utility classes that should, in an ideal world, be part of the JDK. They handle basic things like a read-only interface for arrays or representation for nanosecond precision time instants and periods. When suitable replacement will be available, these classes will be deprecated.
Despite the name of the package, these classes have no dependencies whatsoever on EPICS or DIIRT. They are meant to be general purpose.
epics-util is a part of DIIRT: Data Integration In Real-Time
