Package org.eclipse.compare.rangedifferencer Description
Provides support for finding the differences between
two or three sequences of comparable entities.
Package Specification
The class
RangeDifferencer finds longest sequences of matching and
non-matching comparable entities.
Clients must supply the input to the differencer as an implementation
of the IRangeComparator interface.
An IRangeComparator breaks the input data into a sequence
of entities and provides a method for comparing
one entity with the entity in another IRangeComparator.
For example, to compare two text documents and find longest common
sequences of matching and non-matching lines,
the implementation of IRangeComparator
must break the document into lines and provide a method for testing
whether two lines are considered equal.
See org.eclipse.compare.internal.DocLineComparator for how this can be done.
The differencer returns the differences among these sequences as an
array of RangeDifference objects.
Every single RangeDifference describes the kind of difference
(no change, change, addition, deletion) and the corresponding ranges
of the underlying comparable entities in the two or three inputs.
