public class JournalEntrySizeEstimator
extends Object

Title: JournalEntrySizeEstimator.java

Description: The easiest, simplest, most maintainable way to estimate the size of a formatted JournalEntry is to just have the JournalWriter format it. We save some work and avoid memory overflow issues by removing any data files from the entry before formatting: we know how big the files will be when encoded.
