    Parameters

    path

    The path to the collection.

    Return Value

    A Pipeline with the specified collection as its source.

  • Specifies a collection as the data source for the pipeline.

    Declaration

    Swift

    public func collection(_ coll: CollectionReference) -> Pipeline

    Parameters

    coll

    The CollectionReference of the collection.

    Return Value

    A Pipeline with the specified collection as its source.

  • Specifies a collection group as the data source for the pipeline.

    Swift

    public func collectionGroup(_ collectionId: String) -> Pipeline

    Parameters

  • Specifies the entire database as the data source for the pipeline.

    Declaration

    This allows you to convert a standard Firestore query into a pipeline, which can then be further modified with additional pipeline stages.

    Declaration

    Swift

    public func create(from query: Query) -> Pipeline

    Parameters

    query

    The Query to convert into a pipeline.

    Return Value

    A Pipeline that is equivalent to the given query.
