public static enum System.Logger.Level extends Enum<System.Logger.Level>
System loggers levels. A level has a name and severity. Level values areALL,TRACE,DEBUG,INFO,WARNING,ERROR,OFF, by order of increasing severity.
ALLandOFFare simple markers with severities mapped respectively toInteger.MIN_VALUEandInteger.MAX_VALUE.Severity values and Mapping to
java.util.logging.Level.System logger levels are mapped to java.util.logging levels of corresponding severity.
The mapping is as follows:System.Logger Severity Level Mapping System.Logger Levels java.util.logging Levels ALLALLTRACEFINERDEBUGFINEINFOINFOWARNINGWARNINGERRORSEVEREOFFOFF- Since:

Method Detail
values
public static System.Logger.Level[] values()
Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:for (System.Logger.Level c : System.Logger.Level.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
valueOf
public static System.Logger.Level valueOf(String name)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)- Parameters:
name- the name of the enum constant to be returned.- Returns:
- the enum constant with the specified name
- Throws:
IllegalArgumentException- if this enum type has no constant with the specified nameNullPointerException- if the argument is null
getName
public final String getName()
Returns the name of this level.- Returns:
- this level Enum.name().
getSeverity
public final int getSeverity()
Returns the severity of this level. A higher severity means a more severe condition.- Returns:
- this level severity.
