Method Detail

serialize

public static void serialize(AttributeTypeAndValue atav,
                             java.io.ObjectOutput out)
                      throws java.io.IOException

Serialize an AttributeTypeAndValue object. An AttributeTypeAndValue is composed of a type and a value. The data are stored following the structure :

upName

The User provided ATAV

start

The position of this ATAV in the DN

length

The ATAV length

upType

The user Provided Type

normType

The normalized AttributeType

isHR

Tells if the value is a String or not

if the value is a String :

upValue

The User Provided value.

value

The normalized value.

if the value is binary :

upValueLength

upValue

The User Provided value.

valueLength

value

The normalized value.

Parameters:

atav - the AttributeTypeAndValue to serialize

out - the OutputStream in which the atav will be serialized

Throws:

java.io.IOException - If we can't serialize the atav

deserialize

public static AttributeTypeAndValue deserialize(java.io.ObjectInput in)
                                         throws java.io.IOException

Deserialize an AttributeTypeAndValue object We read back the data to create a new ATAV. The structure read is exposed in the AttributeTypeAndValue.writeExternal(ObjectOutput) method

Parameters:

in - the input stream

Returns:

The constructed AttributeTypeAndValue

Throws:

java.io.IOException - If the input stream can't be read
