Method Detail

values

public static LogLevel[] 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 (LogLevel c : LogLevel.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static LogLevel 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

obtainLogLevel

public static LogLevel obtainLogLevel(int level)

Obtain LogLevel corresponding to given level.
If no corresponding level, SILENT is returned

Parameters:

level - Level to search its corresponding LogLevel

Returns:

Corresponding LogLevel

level

public int level()

Log level order.
More level is low, more log is important

Returns:

Log level order

moreImportant

public LogLevel moreImportant()

Obtain level more important in hierarchy

Returns:

More important level

lessImportant

public LogLevel lessImportant()

Obtain level less important in hierarchy

Returns:

Less important level
