DataPath

open class DataPath: PropertyPath

Used together with DataQuery to represent a select, expand or sort item which is a single-part or multi-part path expression. For example, a path whose OData URL representation is Address/City might be used to access the City property in a complex-typed Address property. Also used to represent paths in OData CSDL.

  • Sets the item index to address an element of a collection typed property.

    Declaration

    Swift

    open func atIndex(_ itemIndex: Int) -> DataPath

    Parameters

    itemIndex

    Zero-based index of the element in the collection.

    Return Value

    This data path.

  • Data type with a DataType.code of DataType.PATH, DataType.PATH_EXPRESSION, DataType.ANNOTATION_PATH, DataType.NAVIGATION_PATH, DataType.STRUCTURAL_PATH, or DataType.DYNAMIC_PATH.

    Declaration

    Swift

    override open var dataType: DataType

  • The defined property for a single-part path or the terminating defined property for a multi-part path.
