class qgis.core.QgsVariantUtils[source]¶

Bases: object

static isNull(variant: Any) → bool[source]¶

Returns True if the specified variant should be considered a NULL value.

This method is more rigorous vs QVariant.isNull(), which will return False on newer Qt versions for tests like QVariant( QDateTime() ).isNull().

Added in version 3.28.

Parameters:: variant (Any)
Return type:: bool

static isNumericType(metaType: QMetaType.Type) → bool[source]¶

Returns True if the specified metaType is a numeric type.

Added in version 3.40.

Parameters:: metaType (QMetaType.Type)
Return type:: bool

static typeToDisplayString(type: QMetaType.Type, subType: QMetaType.Type = QMetaType.Type.UnknownType) → str[source]¶

Returns a user-friendly translated string representing a QVariant type.

The optional subType can be used to specify the type of variant list or map values.

typeToDisplayString(type: QVariant.Type, subType: QVariant.Type = QVariant.Type.Invalid) -> str Returns a user-friendly translated string representing a QVariant type.

The optional subType can be used to specify the type of variant list or map values.

Deprecated since version 3.38: Use the method with a QMetaType.Type argument instead.

Parameters:

type (QMetaType.Type)
subType (QMetaType.Type = QMetaType.Type.UnknownType)

Return type:

str
