  org.apache.directory.shared.ldap.util.AttributeSerializerUtils

public class AttributeSerializerUtils
extends java.lang.Object

static java.lang.Object	deserialize(byte[] buf)
static org.apache.directory.shared.ldap.util.AttributeSerializerUtils.DeserializedAttribute	deserialize(byte[] buf, int offset) Deserializes an attribute from the custom serialization structure.
static byte[]	serialize(java.lang.Object obj) Serializes an attribute using the following structure: [id-length][id-bytes][is-binary][length0][value0]...[lengthN][valueN] Here the id-length is the 4 byte int value of the length of bytes for the id string bytes.

serialize

public static final byte[] serialize(java.lang.Object obj)
                              throws java.io.IOException

Serializes an attribute using the following structure: [id-length][id-bytes][is-binary][length0][value0]...[lengthN][valueN] Here the id-length is the 4 byte int value of the length of bytes for the id string bytes. The id-bytes are the bytes for the id string. The is-binary byte is a true or false for whether or not the values are byte[] or String types. Following this is an array of length-value tuples for the values of the Attributes.

Throws:

java.io.IOException
