signal

Emitted when an attribute was added to the buffer.

attributeDeleted

void QgsVectorLayerEditBuffer::attributeDeleted ( int  idx )

signal

Emitted when an attribute was deleted from the buffer.

Definition at line 282 of file qgsvectorlayereditbuffer.cpp.

changeAttributeValues()

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

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

Returns

true if attributes are well updated, false otherwise

Reimplemented in QgsVectorLayerEditPassthrough.

Definition at line 256 of file qgsvectorlayereditbuffer.cpp.

inline

Returns a map of features with changed attributes values which are not committed.

See also

Definition at line 235 of file qgsvectorlayereditbuffer.cpp.

commitChanges()

bool QgsVectorLayerEditBuffer::commitChanges ( QStringList &  commitErrors )

virtual

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 in QgsVectorLayerEditPassthrough.
