Class PropertyUtils

java.lang.Object

io.quarkus.deployment.recording.PropertyUtils

All Implemented Interfaces:

AutoCloseable

final class PropertyUtils
extends Object
implements AutoCloseable

Delegates to PropertyUtilsBean from Apache Commons Beanutils; must be closed to release any internal caches.

This is inspired by org.apache.commons.beanutils.PropertyUtils, but only exposing the selected methods we use and to avoid allocating some objects which aren't necessary in our limited use cases; also bypasses the classloader scoped cache in favour of an explicit cache control on close, to keep things a bit lighter.
