public interface RequestLogLevelMapper
extends Function<RequestOnlyLog,LogLevel>

A Function that determines the LogLevel of an HttpRequest from a given RequestOnlyLog.

Method Summary

Modifier and Type	Method	Description
default <V> Function<RequestOnlyLog,V>	andThen(Function<? super LogLevel,? extends V> after)	Deprecated. Do not use this method.
@Nullable LogLevel	apply(RequestOnlyLog log)	Returns a LogLevel for the given RequestOnlyLog.
default <V> Function<V,LogLevel>	compose(Function<? super V,? extends RequestOnlyLog> before)	Deprecated. Do not use this method.
static RequestLogLevelMapper	of(LogLevel logLevel)	Creates a new RequestLogLevelMapper which always returns the specified LogLevel.
static RequestLogLevelMapper	of(Class<? extends Throwable> clazz, LogLevel logLevel)	Creates a new RequestLogLevelMapper which returns the specified LogLevel if the given class of RequestOnlyLog.requestCause() is assignable from the specified Throwable class.
default RequestLogLevelMapper	orElse(RequestLogLevelMapper other)	Returns a composed RequestLogLevelMapper which represents a logical OR of this RequestLogLevelMapper and the given other.

Method Details

of

static RequestLogLevelMapper of(LogLevel logLevel)

Creates a new RequestLogLevelMapper which always returns the specified LogLevel.

of

static RequestLogLevelMapper of(Class<? extends Throwable> clazz,
 LogLevel logLevel)

Creates a new RequestLogLevelMapper which returns the specified LogLevel if the given class of RequestOnlyLog.requestCause() is assignable from the specified Throwable class.

apply

@Nullable
@Nullable LogLevel apply(RequestOnlyLog log)

Returns a LogLevel for the given RequestOnlyLog. Returning null lets the next handler specified with orElse(RequestLogLevelMapper) map the RequestOnlyLog.

Specified by:

apply in interface Function<RequestOnlyLog,LogLevel>

orElse

default RequestLogLevelMapper orElse(RequestLogLevelMapper other)

Returns a composed RequestLogLevelMapper which represents a logical OR of this RequestLogLevelMapper and the given other. If this apply(RequestOnlyLog) returns null, then the other RequestLogLevelMapper will be applied.

compose

@Deprecated
default <V> Function<V,LogLevel> compose(Function<? super V,? extends RequestOnlyLog> before)

Deprecated.

Do not use this method.

Returns a composed function that first applies the before function to its input, and then applies this function to the result. If evaluation of either function throws an exception, it is relayed to the caller of the composed function.

Specified by:

compose in interface Function<RequestOnlyLog,LogLevel>

andThen

@Deprecated
default <V> Function<RequestOnlyLog,V> andThen(Function<? super LogLevel,? extends V> after)

Deprecated.

Do not use this method.

Returns a composed function that first applies this function to its input, and then applies the after function to the result. If evaluation of either function throws an exception, it is relayed to the caller of the composed function.

Specified by:

andThen in interface Function<RequestOnlyLog,LogLevel>
