Member Function Documentation

◆ _check()

WikiDiff::_check (   $from_lines,
  $to_lines 
)
inherited

Check a WikiDiff for validity.

This is here only for debugging purposes.

◆ closing()

WordLevelWikiDiff::closing ( )

Get the closing set of lines.

This reconstructs the $to_lines parameter passed to the constructor.

Return values
arrayThe sequence of strings.

Reimplemented from WikiDiff.

◆ isEmpty()

WikiDiff::isEmpty ( )
inherited

Check for empty diff.

Return values
boolTrue iff two sequences were identical.

◆ lcs()

WikiDiff::lcs ( )
inherited

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

This is mostly for diagnostic purposed.

Return values
intThe length of the LCS.

◆ orig()

WordLevelWikiDiff::orig ( )

Get the original set of lines.

This reconstructs the $from_lines parameter passed to the constructor.

Return values
arrayThe original sequence of strings.

Reimplemented from WikiDiff.

◆ reverse()

WikiDiff::reverse ( )
inherited

Compute reversed WikiDiff.

SYNOPSIS:

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

Return values
objectA WikiDiff object representing the inverse of the original diff.

◆ WikiDiff()

WikiDiff::WikiDiff (   $from_lines,
  $to_lines 
)
inherited

Old syntax of class constructor.

Deprecated in PHP7.

Deprecated:
since Moodle 3.1
