org.apache.wicket.util.diff.package.html Maven / Gradle / Ivy
The {@link org.apache.maven.jrcs.diff diff} package implements
the differencing engine that JRCS uses. The engine has the power
of Unix diff, is simple to understand, and can be used
independently of the archive handling functionality. The entry
point to the differencing engine is class {@link
org.apache.maven.jrcs.diff.Diff Diff}.
Text is represented as Object[] because the diff
engine is capable of handling more than plain ascci. In fact,
arrays of any type that implements {@link
java.lang.Object#hashCode hashCode()} and {@link
java.lang.Object#equals equals()} correctly can be subject to
differencing using this library.
Two implementations of the differencing algorithm are provided.
-
{@link SimpleDiff Simple Diff} is a verys imple algorithm that
is fast and works well with very large input sequences, but
that frequently produces result that are subotimal (at times
four or more times larger than GNU diff).
-
{@link org.apache.commons.jrcs.diff.myers.MyersDiff MyersDiff}
is an implementation of Gene Myers
differencing algorithm. Myer's algorithm produces optimum
results (minimum diffs), but consumes considerably more memory
than SimpleDiff, so its not suitable for very large files.
