array
$from_lines, array
$to_lines)

getDiff [line 49]

void getDiff(
)

Returns the array of differences.

getFinal [line 140]

array getFinal(
)

Gets the final set of lines.

This reconstructs the $to_lines parameter passed to the constructor.

Return: The sequence of strings.

[ Top ]

getOriginal [line 122]

array getOriginal(
)

Gets the original set of lines.

This reconstructs the $from_lines parameter passed to the constructor.

Return: The original sequence of strings.

isEmpty [line 87]

boolean isEmpty(
)

Checks for an empty diff.

Return: True if two sequences were identical.

[ Top ]

lcs [line 104]

integer lcs(
)

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

This is mostly for diagnostic purposes.

Return: The length of the LCS.

[ Top ]

reverse [line 68]

Text_Diff reverse(
)

Computes a reversed diff.

Example:

 $diff = &new Text_Diff($lines1, $lines2);

 $rev = $diff->reverse();

Return: A 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.
