Enum System.Logger.Level

java.lang.Object
- java.lang.Enum<System.Logger.Level>
- - java.lang.System.Logger.Level

All Implemented Interfaces:: Serializable, Comparable<System.Logger.Level>

Enclosing interface:: System.Logger

public static enum System.Logger.Level
extends Enum<System.Logger.Level>

System loggers levels. A level has a name and severity. Level values are ALL, TRACE, DEBUG, INFO, WARNING, ERROR, OFF, by order of increasing severity.
ALL and OFF are simple markers with severities mapped respectively to Integer.MIN_VALUE and Integer.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
`ALL`	`ALL`
`TRACE`	`FINER`
`DEBUG`	`FINE`
`INFO`	`INFO`
`WARNING`	`WARNING`
`ERROR`	`SEVERE`
`OFF`	`OFF`

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 name; NullPointerException - 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.
