public class AttributeSerializer
Serializes a attributes object using a custom serialization mechanism so we do not have to rely on Java Serialization which is much more costly.

Deserializes an attribute from the custom serialization structure. |
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. |

[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.
