[MENFORCER-488] EnforcerLogger: Provide isDebugEnabled(), isErrorEnabled(), isWarnEnabled() and isInfoEnabled() (original) (raw)

Similar to what SLF4J Logger (https://www.slf4j.org/api/org/slf4j/Logger.html) and org.apache.maven.plugin.logging.Log provide, there should be a method to determine if a certain log level is enabled. This is useful to put a guard around costly evaluation methods which are only ever useful once a certain level is active.

As switching log level is mostly done via -X command line a isDebugEnabled should be sufficient though for most of the cases.

Using the supplier parameter does not always help e.g. when multiple debug outputs should be surrounded by the same guard.
