| IRangeComparator | | public interface IRangeComparator (Code) | | For breaking an object to compare into a sequence of comparable entities.
It is used by RangeDifferencer to find longest sequences of
matching and non-matching ranges.
For example, to compare two text documents and find longest common sequences
of matching and non-matching lines, the implementation must break the document
into lines. getRangeCount would return the number of lines in the
document, and rangesEqual would compare a specified line given
with one in another IRangeComparator.
Clients should implement this interface; there is no standard implementation.

| Method Summary | |
| int | getRangeCount()
Returns the number of comparable entities. | | boolean | rangesEqual(int thisIndex, IRangeComparator other, int otherIndex)
Returns whether the comparable entity given by the first index
matches an entity specified by the other IRangeComparator and index. | | boolean | skipRangeComparison(int length, int maxLength, IRangeComparator other)
Returns whether a comparison should be skipped because it would be too costly (or lengthy). |
| getRangeCount | | int getRangeCount()(Code) | | Returns the number of comparable entities.
the number of comparable entities |
| rangesEqual | | boolean rangesEqual(int thisIndex, IRangeComparator other, int otherIndex)(Code) | | Returns whether the comparable entity given by the first index
matches an entity specified by the other IRangeComparator and index.
Parameters:
thisIndex - the index of the comparable entity within this IRangeComparator
Parameters:
other - the IRangeComparator to compare this with
Parameters:
otherIndex - the index of the comparable entity within the other IRangeComparator true if the comparable entities are equal |
| skipRangeComparison | | boolean skipRangeComparison(int length, int maxLength, IRangeComparator other)(Code) | | Returns whether a comparison should be skipped because it would be too costly (or lengthy).
Parameters:
length - a number on which to base the decision whether to returntrue or false
Parameters:
maxLength - another number on which to base the decision whether to returntrue or false
Parameters:
other - the other IRangeComparator to compare with true to avoid a too lengthy range comparison |
