Old description: Mapbender data source module

Components abstracting raw doctrine tables into repositories.

The base DataStore is a repository promoting loaded rows into DataItem objects, and also supports DataItem objects when updating / inserting.

FeatureType is an extended repository type with spatial data support. It loads / stores Feature objects, with dedicated methods for accessing / replacing the geometry. The geometry is internally always an EWKT, but methods are provided to get / update the plain WKT or the SRID individually.

Only a single geometry column per table is supported.

Main repository methods

Method search loads all rows from the table and promotes them into an array of DataItem / Feature objects. Accepts an array of controlling parameters. Allowed params are maxResults, where (string; additional SQL where clause). FeatureType additionally supports params srid (explicit geometry output SRID) and intersect (string; (E)WKT geometry to spatially limit results).

Method count Accepts the same parameters as search, but returns only the number of matched rows.

Method getById loads one DataItem / Feature. Filters are skipped.

Methods save, insert, update perform storage. save auto-inflects to insert or update, depending on the presence of an id in the passed argument. These methods accept either DataItem / Feature objects or arrays. The affected or new row is reloaded and returned as a DataItem / Feature object.

Method delete removes the row corresponding with an id or a specific DataItem / Feature object.

Configuring repositories

Named DataStore / FeatureType repositorys can be pre-configured globally via container parameters (dataStores and featureTypes respectively), or instantiated ad hoc from a configuration array.

DataStore configuration supports the following values:

NOTE: you should not attempt placing spatial data into the "default" database containing your Doctrine entities. You will encounter errors running Doctrine schema updates.

NOTE: Both the filter setting and the where search param may use a magic placeholder :userName, which is automatically bound to the name of the user running the query.
