Enum Constant Summary

Enum Constants

Enum Constant and Description
DEBUG A very low and rarely useful form of Logging.
ERROR An error is an indication that DiSCo has detected a serious problem, and was unable to proceed as requested.
FATAL A fatal error is the most serious kind of log.
INFO By default the minimum visible level of Logging.
TRACE The lowest and least useful form of Logging in most circumstances.
WARN A warning is generally informative, but may be a canary for missing functionality.

Method Summary

Modifier and Type	Method and Description
static Logger.Level	valueOf(java.lang.String name) Returns the enum constant of this type with the specified name.

Enum Constant Detail

TRACE

public static final Logger.Level TRACE

The lowest and least useful form of Logging in most circumstances. Can tend to be extremely verbose, and is unlikely to be useful except for DiSCo developers, or under rare debugging scenarios. Enabled by the DiSCo 'extraverbose' command line argument.

DEBUG

public static final Logger.Level DEBUG

A very low and rarely useful form of Logging. Can tend to be somewhat verbose, and is unlikely to be useful except for DiSCo developers, or under rare debugging scenarios. Enabled by the DiSCo 'verbose' command line argument.

INFO

public static final Logger.Level INFO

By default the minimum visible level of Logging. Info logs are notifications of major, normal, events during the software lifetime.

WARN

public static final Logger.Level WARN

A warning is generally informative, but may be a canary for missing functionality. When only warnings are present the software is expected to proceed without harm, but may be degraded.

ERROR

public static final Logger.Level ERROR

An error is an indication that DiSCo has detected a serious problem, and was unable to proceed as requested. There is a possibility or likelihood that the service-under-test will encounter its own problems or failures

FATAL

public static final Logger.Level FATAL

A fatal error is the most serious kind of log. It indicates that the service-under-test is unlikely to be able to continue operating normally.

Method Detail

values

public static 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 (Logger.Level c : 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 Logger.Level valueOf(java.lang.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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
