Constructor Diff (line 542)

Constructor.

Computes diff between sequences of strings.

Diff Diff ($from_lines $from_lines, $to_lines $to_lines)

$from_lines $from_lines: array An array of strings. (Typically these are lines from a file.)
$to_lines $to_lines: array An array of strings.

finaltext (line 622)

Get the final set of lines.

This reconstructs the $to_lines parameter passed to the constructor.

return: The sequence of strings.

array finaltext ()

isEmpty (line 572)

Check for empty diff.

return: True iff two sequences were identical.

bool isEmpty ()

lcs (line 587)

Compute the length of the Longest Common Subsequence (LCS).

This is mostly for diagnostic purposed.

return: The length of the LCS.

int lcs ()

orig (line 604)

Get the original set of lines.

This reconstructs the $from_lines parameter passed to the constructor.

return: The original sequence of strings.

array orig ()

reverse (line 558)

Compute reversed Diff.

SYNOPSIS:

$diff = new Diff($lines1, $lines2); $rev = $diff->reverse();

return: Diff object representing the inverse of the original diff.

object A reverse ()

_check (line 637)

Check a Diff for validity.

This is here only for debugging purposes.

void _check ( $from_lines, $to_lines)

$from_lines
$to_lines
