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

Slf4jExceptionHandler is an enum implementation of the ExceptionHandler interface. It uses SLF4J (Simple Logging Facade for Java) to handle exceptions based on the level of logging severity. It supports four levels of logging severity: ERROR, WARN, PERF and DEBUG.

Each instance of Slf4jExceptionHandler logs at a specific level and corresponds to a LogLevel enum. This is used to map LogLevel enums to their corresponding Slf4jExceptionHandler instances via the valueOf(LogLevel logLevel) method.

The DEBUG instance also overrides the isEnabled(Class clazz) method, using the isDebugEnabled() method from SLF4J's Logger class.

There's also a utility method isJUnitTest() which is used to detect if the current execution context is a JUnit test.

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

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.
