generateDiff

public static DiffResult generateDiff(ContentEntityObject originalPage,

                               throws org.apache.commons.jrcs.diff.DifferentiationFailedException

Deprecated.

Calculates the difference between two pages and returns the result as HTML.

The CSS styles used are:

4. differror - (rare) used if there is an error

Parameters:
