Functions

connectEndOfData ulong connectEndOfData(T callback, Flag!"After" after): Connect to EndOfData signal.
connectRowChanged ulong connectRowChanged(T callback, Flag!"After" after): Connect to RowChanged signal.
getColumnForParam int getColumnForParam(gda.holder.Holder param): Get the column number in the #GdaDataModel for which iter is an iterator as represented by the param parameter
getHolderForField gda.holder.Holder getHolderForField(int col): Fetch a pointer to the #GdaHolder object which is synchronized with data at column col
getRow int getRow(): Get the row which iter represents in the data model
getValueAt gobject.value.Value getValueAt(int col): Get the value stored at the column col in iter. The returned value must not be modified.
getValueAtE gobject.value.Value getValueAtE(int col): Get the value stored at the column col in iter. The returned value must not be modified.
getValueForField gobject.value.Value getValueForField(string fieldName): Get the value stored at the column field_name in iter
invalidateContents void invalidateContents(): Declare all the parameters in iter invalid, without modifying the #GdaDataModel iter is for or changing the row it represents. This method is for internal usage. Note that for gda.data_model_iter.DataModelIter.isValid to return false, it is also necessary to set the "current-row" property to -1.
isValid bool isValid(): Tells if iter is a valid iterator (if it actually corresponds to a valid row in the model)
moveNext bool moveNext(): Moves iter one row further than where it already is (synchronizes the values of the parameters in iter with the values at the new row).
movePrev bool movePrev(): Moves iter one row before where it already is (synchronizes the values of the parameters in iter with the values at the new row).
moveToRow bool moveToRow(int row): Synchronizes the values of the parameters in iter with the values at the row row.
self DataModelIter self(): Returns this, for use in with statements.
setValueAt bool setValueAt(int col, gobject.value.Value value): Sets a value in iter, at the column specified by col

validateChanges bool validateChanges [@property setter]: Set validateChanges property.
newFromSpecNode gda.set.Set newFromSpecNode(libxml2.types.NodePtr xmlSpec): Creates a new #GdaSet object from the xml_spec specifications
newFromSpecString gda.set.Set newFromSpecString(string xmlSpec): Creates a new #GdaSet object from the xml_spec specifications
newReadOnly gda.set.Set newReadOnly(gda.holder.Holder[] holders): Creates a new #GdaSet like gda.set.Set.new_, but does not allow modifications to any of the #GdaHolder object in holders. This function is used for Libgda's database providers' implementation.
errorQuark glib.types.Quark errorQuark()
addHolder bool addHolder(gda.holder.Holder holder): Adds holder to the list of holders managed within set.
copy gda.set.Set copy(): Creates a new #GdaSet object, copy of set
getGroup gda.set_group.SetGroup getGroup(gda.holder.Holder holder): Finds a #GdaSetGroup which lists a #GdaSetNode containing holder, don't modify the returned structure.
getHolder gda.holder.Holder getHolder(string holderId): Finds a #GdaHolder using its ID
getHolderValue gobject.value.Value getHolderValue(string holderId): Get the value of the #GdaHolder which ID is holder_id
getNode gda.set_node.SetNode getNode(gda.holder.Holder holder): Finds a #GdaSetNode holding information for holder, don't modify the returned structure
getNthHolder gda.holder.Holder getNthHolder(int pos): Finds a #GdaHolder using its position
getSource gda.set_source.SetSource getSource(gda.holder.Holder holder): Finds a #GdaSetSource which contains the #GdaDataModel restricting the possible values of holder, don't modify the returned structure.
getSourceForModel gda.set_source.SetSource getSourceForModel(gda.data_model.DataModel model): Finds the #GdaSetSource structure used in set for which model is a the data model (the returned structure should not be modified).
isValid bool isValid(): This method tells if all set's #GdaHolder objects are valid, and if they represent a valid combination of values, as defined by rules external to Libgda: the "validate-set" signal is emitted and if none of the signal handlers return an error, then the returned value is TRUE, otherwise the return value is FALSE as soon as a signal handler returns an error.
mergeWithSet void mergeWithSet(gda.set.Set setToMerge): Add to set all the holders of set_to_merge. Note1: only the #GdaHolder of set_to_merge for which no holder in set has the same ID are merged Note2: all the #GdaHolder merged in set are still used by set_to_merge.
removeHolder void removeHolder(gda.holder.Holder holder): Removes a #GdaHolder from the list of holders managed by set
replaceSourceModel void replaceSourceModel(gda.set_source.SetSource source, gda.data_model.DataModel model): Replaces source->data_model with model, which must have the same characteristics as source->data_model (same column types)
connectHolderAttrChanged ulong connectHolderAttrChanged(T callback, Flag!"After" after): Connect to HolderAttrChanged signal.
connectHolderChanged ulong connectHolderChanged(T callback, Flag!"After" after): Connect to HolderChanged signal.
connectHolderTypeSet ulong connectHolderTypeSet(T callback, Flag!"After" after): Connect to HolderTypeSet signal.
connectPublicDataChanged ulong connectPublicDataChanged(T callback, Flag!"After" after): Connect to PublicDataChanged signal.
connectSourceModelChanged ulong connectSourceModelChanged(T callback, Flag!"After" after): Connect to SourceModelChanged signal.
connectValidateHolderChange ulong connectValidateHolderChange(T callback, Flag!"After" after): Connect to ValidateHolderChange signal.
connectValidateSet ulong connectValidateSet(T callback, Flag!"After" after): Connect to ValidateSet signal.
