Layer - Feature Service

URL	`http://<adminfeatureservice-url>/<layerId>`
Supported Operations	Refresh
Parent Resource	Feature Service

Description

The layer resource represents a single feature layer or a non spatial table in a feature service. A feature layer is a table or view with at least one spatial column.

For tables, it provides basic information about the table such as its id, name, fields, types and templates.

For feature layers, in addition to the table information above, it provides information such as its geometry type, min and max scales, and spatial reference.

Each type includes information about the type such as the type id, name, and definition expression. Sub-types also include a default symbol and a list of feature templates.

Each feature template includes a template name, description and a prototypical feature.

The property supportsRollbackOnFailures will be true to indicate the support for transactional edits.

The property maxRecordCount returns the maximum number of records that will be returned at once for a query.

The property capabilities returns Query, Create, Delete, Update, and Editing capabilities. The Editing capability will be included if Create, Delete or Update is enabled for a Feature Service.

Note, query and edit operations are not available on a layer in the adminstrative view.

Parameters
