Convert a tbl_sql object to an overture_call object

Adds the overture_call class to a tbl_sql object. open_curtain() does this for you; call it directly on a lazy table of Overture data you built yourself, so that collect() returns sf and record_overture() knows the type and theme of the data.

Usage

as_overture(x, type, theme = get_theme_from_type(type), release = NULL)

Arguments

x: A tbl_sql object representing an Overture Maps dataset.
type: A string specifying the type of overture dataset to read. Setting to "*" or NULL will read all types for a given theme. See overture_types() for the valid values.
theme: Inferred from type by default. Must be set if type is "*" or NULL.
release: The Overture release the data came from, such as "2026-08-19.0", or NULL if unknown.

Value

A tbl_sql object with the additional class overture_call and an overture_playbill attribute: a list with type, theme and release.

Examples

if (FALSE) { # interactive()
# The open_curtain() function already uses as_overture() internally,
# but you can also use it directly:
conn <- stage_conn()
division <- open_curtain("division", tablename = "test")

class(division)

# views
division2 <- tbl(conn, "test")
division2 <- as_overture(division2, "division")

strike_stage(conn)
}
