Example

example

EastingNorthing { easting: 530000.0 northing: 180000.0 crs: "EPSG:27700" }

Good to know

Jadpo stores it as written and doesn't convert it to or from a Point.
== tells you whether two are the same. < and list.sort_by don't take it, so sort by one of its parts instead.

In JSON

An object of its parts, in a request, a response or json.write:

json

{"easting":"530000","northing":"180000","crs":"EPSG:27700"}{"easting":"448251.795","northing":"5411932.678","crs":"EPSG:32630"}

Details

Text form, storage, how it is shown, and operations

EastingNorthing is in the group Geospatial, and has been in Jadpo since 0.1.0.

Text form

It has no single text form, so text.from and text.parse don't take it.

How it is stored

It is stored in 3 columns, each named for the field, _ and its suffix. This is {"easting":"448251.795","northing":"5411932.678","crs":"EPSG:32630"}:

Column	Type	Holds
`<field>_easting`	`numeric`	`448251.795`
`<field>_northing`	`numeric`	`5411932.678`
`<field>_crs`	`text`	`'EPSG:32630'`

How it is shown to people

text.format(value, locale:) shows it to people in their locale.

With locale: Locale.en_gb:

Value	Shown
`{"easting":"530000","northing":"180000","crs":"EPSG:27700"}`	`easting 530,000, northing 180,000 (EPSG:27700)`
`{"easting":"448251.795","northing":"5411932.678","crs":"EPSG:32630"}`	`easting 448,251.795, northing 5,411,932.678 (EPSG:32630)`

Operations

It also takes text.format, json.read, json.write and ==. How every standard type behaves says how they work.
