)

Public Static Functions Documentation

function attributeIsNull

static Q_INVOKABLE bool QfFeatureUtils::attributeIsNull (
    const QVariant & value
)

Returns TRUE if an attribute value is null.

function createBlankFeature

static Q_INVOKABLE QgsFeature QfFeatureUtils::createBlankFeature (
    const QgsFields & fields=QgsFields(),
    const QgsGeometry & geometry=QgsGeometry()
)

Returns a new feature with its fields completely blank.

function createFeature

static Q_INVOKABLE QgsFeature QfFeatureUtils::createFeature (
    QgsVectorLayer * layer,
    const QgsGeometry & geometry=QgsGeometry(),
    const QfGnssPositionInformation & positionInformation=QfGnssPositionInformation (),
    const QfCloudUserInformation & cloudUserInformation=QfCloudUserInformation ()
)

Returns a new feature with its fields set to default values.

function createField

static Q_INVOKABLE QgsField QfFeatureUtils::createField (
    const QString & name,
    FieldType type,
    const QString & typeName=QString(),
    int length=0,
    int precision=0,
    const QString & comment=QString()
)

Returns a new a field gadget.

function createFields

static Q_INVOKABLE QgsFields QfFeatureUtils::createFields (
    const QList< QgsField > & fields
)

Returns a new a fields gadget.

function displayName

static Q_INVOKABLE QString QfFeatureUtils::displayName (
    QgsVectorLayer * layer,
    const QgsFeature & feature
)

Returns the display name of a given feature.

Parameters:

layer the vector layer containing the feature
feature the feature to be named

function extent

static Q_INVOKABLE QgsRectangle QfFeatureUtils::extent (
    QgsQuickMapSettings * mapSettings,
    QgsVectorLayer * layer,
    const QgsFeature & feature,
    bool skipSinglePointLogic=false
)

Returns the map extent encompassig a given feature.

Parameters:

mapSettings the map settings used to determine the CRS
layer the vector layer containing the feature
feature the feature from which the geometry will be used
skipSinglePointLogic when TRUE, the special handling for determining a single point extent will be skipped

Returns:

a QgsRectangle extent

function featuresFromJsonString

static Q_INVOKABLE QList< QgsFeature > QfFeatureUtils::featuresFromJsonString (
    const QString & string
)

Returns a list of features while attempting to parse a GeoJSON string. If the string could not be parsed, an enmpty list will be returned.
