Enum Slf4jExceptionHandler

java.lang.Object

java.lang.Enum<Slf4jExceptionHandler>

net.openhft.chronicle.core.onoes.Slf4jExceptionHandler

All Implemented Interfaces:

Serializable, Comparable<Slf4jExceptionHandler>, ExceptionHandler

public enum Slf4jExceptionHandler
extends Enum<Slf4jExceptionHandler>
implements ExceptionHandler

Exception handler that logs using the SLF4J API.

Each enum constant represents a logging level and calls the matching method on the SLF4J Logger. When SLF4J fails to initialise, or the logger throws at runtime, the implementation writes to System.err instead.

Method Detail

values

public static Slf4jExceptionHandler[] 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 (Slf4jExceptionHandler c : Slf4jExceptionHandler.values())
    System.out.println(c);

Returns:

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

valueOf

public static Slf4jExceptionHandler 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

on

public void on(@NotNull
               @NotNull org.slf4j.Logger logger,
               @Nullable
               @Nullable String message,
               @Nullable
               @Nullable Throwable thrown)

Description copied from interface: ExceptionHandler

Handles an exception with the given logger, message and throwable.

Specified by:

on in interface ExceptionHandler

Parameters:

logger - the logger used to record the error

message - a custom message detailing the error, may be null

thrown - the throwable instance representing the error, may be null

on

public void on(@NotNull
               @NotNull Class<?> clazz,
               @Nullable
               @Nullable String message,
               @Nullable
               @Nullable Throwable thrown)

Description copied from interface: ExceptionHandler

Handles an exception for the given class, message and throwable. If logging fails this method attempts to log again at ERROR level.

Specified by:

on in interface ExceptionHandler

Parameters:

clazz - the class where the exception occurred

message - a custom message providing additional information or null

thrown - the exception that needs to be handled, may be null

valueOf

public static Slf4jExceptionHandler valueOf(LogLevel logLevel)

Returns the appropriate Slf4jExceptionHandler value based on the given LogLevel.

Parameters:

logLevel - the LogLevel enum to convert.

Returns:

the corresponding Slf4jExceptionHandler value.
