Static Methods

deserialize(byte[] value, int flags)

public static Object deserialize(byte[] value, int flags)

Deserialize the object, according to its flags. This would have private visibility, but is also used by LocalMemcacheService for the increment operation.

Parameters
Name	Description
value	byte[]
flags	int

Returns
Type	Description
Object	the Object originally stored

Exceptions
Type	Description
ClassNotFoundException	if the object can't be re-instantiated due to being an unlocatable type
IOException	if the object can't be re-instantiated due to being an unlocatable type

makePbKey(Object key)

public static byte[] makePbKey(Object key)

Converts the user's key Object into a byte[] for the MemcacheGetRequest. Because the underlying service has a length limit, we actually use the SHA1 hash of the serialized object as its key if it's not a basic type. For the basic types (that is, String, Boolean, and the fixed-point numbers), we use a human-readable representation.

Parameter
Name	Description
key	Object

Returns
Type	Description
byte[]	hash result. For the key null, the hash is also null.

Exceptions
Type	Description
IOException

serialize(Object value)

public static MemcacheSerialization.ValueAndFlags serialize(Object value)

Parameter
Name	Description
value	Object

Returns
Type	Description
MemcacheSerialization.ValueAndFlags	the ValueAndFlags containing a serialized representation of the Object and the flags to hint deserialization.

Exceptions
Type	Description
IOException	for serialization errors, normally due to a non-serializable object type
