Properties Summary

public array
$ignoreChanges
Array of object fields to unset from the data object before calculating SHA1 hash. This allows us to detect a meaningful change in the database row using the hash. This can be read from the #__content_types content_history_options column.
Since
  • 3.2
public array
$convertToInt
Array of object fields to convert to integers before calculating SHA1 hash. Some values are stored differently when an item is created than when the item is changed and saved. This works around that issue.
Since
  • 3.2
