Enum CacheWriteMode

java.lang.Object

java.lang.Enum<CacheWriteMode>

com.trivago.triava.tcache.CacheWriteMode

All Implemented Interfaces:

Serializable, Comparable<CacheWriteMode>

public enum CacheWriteMode
extends Enum<CacheWriteMode>

Defines how entries are put in the cache. Either they are put using the reference of the instance (Identity), cloned via clone() (Clone) or interned similar to String.intern() (Intern). Call isStoreByValue() to determine whether the store method is store-by-value.

Method Detail

values

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

Returns:

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

valueOf

public static CacheWriteMode 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

fromStoreByValue

public static CacheWriteMode fromStoreByValue(boolean storeByValue)

Converts the JSR isStoreByValue to the corresponding CacheWriteMode.

Parameters:

storeByValue - true for store by value, false otherwise

Returns:

The corresponding CacheWriteMode

isStoreByValue

public boolean isStoreByValue()

Returns whether this CacheWriteMode is using store-by-value as defined by JSR107. Only for Serialize true is returned. Mode Identity always shares Objects, and Intern also most of the time.

Returns:

true, if the mode is to store by value
