Properties
Properties		Defined By
	new_model : Gda.DataModel	Gda.DataComparator
	object : GObject.Object read only	Gda.DataComparator
	old_model : Gda.DataModel	Gda.DataComparator
	priv : Gda.DataComparatorPrivate read only	Gda.DataComparator

Methods / Constructors
Method / Constructor		Defined By
	new Gda.DataComparator (Object *properties) Create a new Gda.DataComparator Create a new Gda.DataComparator Parameters: Object properties*
	new Gda.DataComparator.c_new (DataModel *old_model, DataModel new_model) : Gda.DataComparator Create a new Gda.DataComparator Create a new Gda.DataComparator Parameters: Gda.DataModel old_model* Required (not null) Gda.DataModel new_model Required (not null) Returns: Gda.DataComparator a new GdaDataComparator object
	compute_diff () : Boolean Actually computes the differences between the data models for which comp is defined. Actually computes the differences between the data models for which comp is defined. For each difference computed, stored in a GdaDiff structure, the "diff-computed" signal is emitted. If one connects to this signal and returns FALSE in the signal handler, then computing differences will be stopped and an error will be returned. Returns: Boolean	Gda.DataComparator
	get_diff (Number *pos) : Gda.Diff Get a pointer to the GdaDiff* structure representing the difference which number is pos Get a pointer to the GdaDiff structure representing the difference which number is pos Parameters: Number pos Required (not null) Returns: Gda.Diff a pointer to a GdaDiff, or NULL if pos is invalid	Gda.DataComparator
	get_n_diffs () : Number Get the number of differences as computed by the last time gda_data_comparator_compute_diff() was called. Get the number of differences as computed by the last time gda_data_comparator_compute_diff() was called. Returns: Number	Gda.DataComparator
	set_key_columns (Array *col_numbers, Number nb_cols) : none Defines the columns which will be used as a key when searching data. Defines the columns which will be used as a key when searching data. This is not mandatory but will speed things up as less data will be processed. Parameters: Array col_numbers* Required (not null) an array of nb_cols values Number nb_cols Required (not null) Returns: none	Gda.DataComparator

Events - usage syntax: this.signals.EVENTNAME.connect( Function )

	diff_computed (DataComparator *self, void *object) : Boolean Parameters: Gda.DataComparator self* void* object Returns: {Boolean}	Gda.DataComparator
