Assign
Severity to a Source 
Use the constants provided directly: Severity.DEBUG, Severity.PATH, Severity.INFO, Severity.WARNING, Severity.ERROR, Severity.FATAL, Severity.ALL, and Severity.NONE. For more information about the various severity level definitions, see Appendix A.
Normally, you assign a severity to the source using: loc.setEffectiveSeverity(Severity.INFO);. Any messages with severity lower than INFO will be discarded, others will be directed to the destination.
Introduce Concept of Hierarchical Severity
Assign severity to the parent, and its children will automatically inherit the assigned severity.
static final Location loc = Location.getLocation(com.sap.fooPackage); loc.setEffectiveSeverity(Severity.INFO); |
If you have a location com.sap.fooPackage.Class1, it must have already inherited the severity INFO.
For more information about hierarchical severities, see Hierarchical Severity Inheritance.
Default with Strictest Severity
By default, the source object (assume the ascendants have not been assigned severity yet) has SEVERITY.NONE. Therefore, you can freely enable the output methods in the source code, but the actual logging is not activated until it is explicitly switched on when things are ready.
