Enum CacheDeserializedValues

java.lang.Object

java.lang.Enum<CacheDeserializedValues>

com.hazelcast.config.CacheDeserializedValues

All Implemented Interfaces:

Serializable, Comparable<CacheDeserializedValues>

public enum CacheDeserializedValues
extends Enum<CacheDeserializedValues>

Control caching of de-serialized values. Caching makes query evaluation faster but it costs memory. To maintain reusability, cached values are used by read-only operations only and they are never passed to user-code where they could be accidentally mutated. Users will always get a fresh object, which they are free to mutate. It does not have any effect when Portable serialization or InMemoryFormat.OBJECT format is used.

Since:

3.6

Method Detail

values

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

Returns:

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

valueOf

public static CacheDeserializedValues 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

parseString

public static CacheDeserializedValues parseString(String string)

Create instance from String

Parameters:

string - the string value to parse

Returns:

instance of CacheDeserializedValues

Throws:

IllegalArgumentException - when unknown value is passed
