<DL>
<DD>Expert:  Load the size of this <A HREF="../../../../org/apache/lucene/document/Field.html" title="class in org.apache.lucene.document"><CODE>Field</CODE></A> rather than its value.
 Size is measured as number of bytes required to store the field == bytes for a binary or any compressed value, and 2*chars for a String value.
 The size is stored as a binary value, represented as an int in a byte[], with the higher order byte first in [0]
