Definition at line 20 of file qgsvectorlayereditpassthrough.cpp.

Member Function Documentation

◆ addAttribute()

bool QgsVectorLayerEditPassthrough::addAttribute ( const QgsField & field )

overridevirtual

Add an attribute field (but does not commit it) returns true if the field was added.

Reimplemented from QgsVectorLayerEditBuffer.

Definition at line 133 of file qgsvectorlayereditpassthrough.cpp.

◆ addFeature()

bool QgsVectorLayerEditPassthrough::addFeature ( QgsFeature & f )

overridevirtual

Adds a feature.

Parameters

f	feature to add

Returns: True in case of success and False in case of error

Reimplemented from QgsVectorLayerEditBuffer.

Definition at line 31 of file qgsvectorlayereditpassthrough.cpp.

◆ addFeatures()

bool QgsVectorLayerEditPassthrough::addFeatures ( QgsFeatureList & features )

overridevirtual

Insert a copy of the given features into the layer (but does not commit it)

Reimplemented from QgsVectorLayerEditBuffer.

Definition at line 46 of file qgsvectorlayereditpassthrough.cpp.

◆ changeAttributeValue()

bool QgsVectorLayerEditPassthrough::changeAttributeValue	(	QgsFeatureId	fid,
		int	field,
		const QVariant &	newValue,
		const QVariant &	oldValue = `QVariant()`
	)

overridevirtual

Changed an attribute value (but does not commit it)

Reimplemented from QgsVectorLayerEditBuffer.

Definition at line 97 of file qgsvectorlayereditpassthrough.cpp.

◆ changeAttributeValues()

bool QgsVectorLayerEditPassthrough::changeAttributeValues	(	QgsFeatureId	fid,
		const QgsAttributeMap &	newValues,
		const QgsAttributeMap &	oldValues
	)

overridevirtual

Changes values of attributes (but does not commit it).

Returns: true if attributes are well updated, false otherwise

Note: added in QGIS 2.18

Reimplemented from QgsVectorLayerEditBuffer.

Definition at line 112 of file qgsvectorlayereditpassthrough.cpp.

◆ changeGeometry()

bool QgsVectorLayerEditPassthrough::changeGeometry	(	QgsFeatureId	fid,
		QgsGeometry *	geom
	)

overridevirtual

Change feature's geometry.

Reimplemented from QgsVectorLayerEditBuffer.

Definition at line 84 of file qgsvectorlayereditpassthrough.cpp.

◆ commitChanges()

bool QgsVectorLayerEditPassthrough::commitChanges ( QStringList & commitErrors )

overridevirtual

Attempts to commit any changes to disk.

Returns the result of the attempt. If a commit fails, the in-memory changes are left alone.

This allows editing to continue if the commit failed on e.g. a disallowed value in a Postgres database - the user can re-edit and try again.

The commits occur in distinct stages, (add attributes, add features, change attribute values, change geometries, delete features, delete attributes) so if a stage fails, it's difficult to roll back cleanly. Therefore any error message also includes which stage failed so that the user has some chance of repairing the damage cleanly.

Reimplemented from QgsVectorLayerEditBuffer.
