Description:

Content:

Properties:

• public DataModel new_model { owned get; set; }
• public DataModel old_model { owned get; set; }

Static methods:

• public static Quark error_quark ()

Creation methods:

• public DataComparator (DataModel old_model, DataModel new_model)
  Creates a new comparator to compute the differences from old_model to new_model: if one applies all the computed differences (as Diff structures) to old_model, the resulting data model should have the same contents as new_model.

Methods:

• public bool compute_diff () throws Error
  Actually computes the differences between the data models for which this is defined.
• public unowned Diff? get_diff (int pos)
  Get a pointer to the Diff structure representing the difference which number is pos
• public int get_n_diffs ()
  Get the number of differences as computed by the last time compute_diff was called.
• public void set_key_columns (int[] col_numbers)
  Defines the columns which will be used as a key when searching data.

Signals:

• public virtual signal bool diff_computed (void* diff)
