Method Detail

toLevel

public static Level toLevel(java.lang.String sArg)

Deprecated.

Convert the string passed as argument to a level. If the conversion fails, then this method returns DEBUG.

toLevel

public static Level toLevel(int val)

Deprecated.

Convert an integer passed as argument to a level. If the conversion fails, then this method returns DEBUG.

toLevel

public static Level toLevel(int val,
                            Level defaultLevel)

Deprecated.

Convert an integer passed as argument to a level. If the conversion fails, then this method returns the specified default.

toLevel

public static Level toLevel(java.lang.String sArg,
                            Level defaultLevel)

Deprecated.

Convert the string passed as argument to a level. If the conversion fails, then this method returns the value of defaultLevel.
