Method Summary

Methods

Modifier and Type	Method and Description
static <K,V,M extends ChronicleMap<K,V>> MapEventListener<K,V,M>	bytesLogging() Returns the map event listener, which logs strings like "Meta: [meta bytes] | [key bytes] = [value bytes]", where bytes are meta, key and value areas from Bytes passed to MapEventListener methods, printed in ASCII coding.
static <K,V,M extends ChronicleMap<K,V>> MapEventListener<K,V,M>	keyValueLogging() Returns the map event listener, which logs strings like "map file opType key value", where opType is either "get", "put" or "remove", to the logger provided by SLF4J.
static <K,V,M extends ChronicleMap<K,V>> MapEventListener<K,V,M>	nop() Returns the no-op event listener, i.

Method Detail

nop

public static <K,V,M extends ChronicleMap<K,V>> MapEventListener<K,V,M> nop()

Returns the no-op event listener, i. e. all it's method implementations have empty bodies.

Type Parameters:

K - the map key type

V - the map value type

M - the ChronicleMap subclass, or ChronicleMap type itself. Typically this type should be just ChronicleMap.

Returns:

the no-op event listener

bytesLogging

public static <K,V,M extends ChronicleMap<K,V>> MapEventListener<K,V,M> bytesLogging()

Returns the map event listener, which logs strings like "Meta: [meta bytes] | [key bytes] = [value bytes]", where bytes are meta, key and value areas from Bytes passed to MapEventListener methods, printed in ASCII coding.

Type Parameters:

K - the map key type

V - the map value type

M - the ChronicleMap subclass, or ChronicleMap type itself. Typically this type should be just ChronicleMap.

Returns:

the bytes logging event listener

keyValueLogging

public static <K,V,M extends ChronicleMap<K,V>> MapEventListener<K,V,M> keyValueLogging()

Returns the map event listener, which logs strings like "map file opType key value", where opType is either "get", "put" or "remove", to the logger provided by SLF4J.

Type Parameters:

K - the map key type

V - the map value type

M - the ChronicleMap subclass, or ChronicleMap type itself. Typically this type should be just ChronicleMap.

Returns:

the logging event listener
