Text_Diff Text_Diff(
$from_lines
$from_lines, $to_lines
$to_lines)

Computes diff between sequences of strings.

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

[line 138]

array (
)

Get the final set of lines.

This reconstructs the $to_lines parameter passed to the constructor.

Return: The sequence of strings.

[ Top ]

getDiff [line 49]

void getDiff(
)

Return the array of differences.

[ Top ]

isEmpty [line 82]

boolean isEmpty(
)

Check for empty diff.

Return: True iff two sequences were identical.

[ Top ]

lcs [line 99]

int lcs(
)

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

This is mostly for diagnostic purposed.

Return: The length of the LCS.

[ Top ]

orig [line 118]

array orig(
)

Get the original set of lines.

This reconstructs the $from_lines parameter passed to the constructor.

Return: The original sequence of strings.

[ Top ]

reverse [line 67]

object A reverse(
)

Compute reversed diff.

SYNOPSIS:

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

Return: Diff object representing the inverse of the original diff. Note that we purposely don't return a reference here, since this essentially is a clone() method.
