Package org.kiwiproject.beta.slf4j

Class KiwiSlf4j

java.lang.Object

org.kiwiproject.beta.slf4j.KiwiSlf4j

@Beta
public final class KiwiSlf4j
extends Object

Utilities for SLF4J, mainly to allow logging a message at a specified level. Sometimes it is useful to be able not just to change the log level of loggers at runtime, but also to select the level of specific log statements. For example, instead of having to hard code a LOG.debug(...), you can use one of the log methods in this utility to permit changing the level at which a specific statement is logged. This is more granular than just changing an entire Logger's level and is extremely useful in some situations.

toLevelIgnoreCase

public static org.slf4j.event.Level toLevelIgnoreCase(String levelNameString)

Matches levelNameString to a value in Level, independent of the character case (lower or upper).

For example, the strings "WARN", "warn", and "Warn" all match Level.WARN.

Parameters:

levelNameString - a String whose uppercased value maps to one of the values in Level

Returns:

the matching SLF4J Level

Throws:

IllegalArgumentException - if levelNameString is blank or there is no matching Level
