Class DimensionLayer

  • All Implemented Interfaces:
    RemoteResource, LayerContent, Loadable
    public final class DimensionLayer
extends Layer
implements RemoteResource
    A layer that can visualize dimension features data.

    Dimension features are a special kind of annotation feature for showing specific lengths or distances on a map. A dimension may indicate the length of a side of a building or land parcel, or the distance between two features, such as a fire hydrant and the corner of a building. They are described in detail in "Dimension".

    Each Dimension feature has specific text and specific locations for its schematic lines and arrows.

    Dimension features are not linked to other point, line or polygon features, even if the dimension measurement was created to refer to one or more features.

    You can construct a dimension layer using a feature table containing dimension features:

    Dimension layers can be taken offline from a feature service hosted on ArcGIS Enterprise 10.9 or later, using the GeodatabaseSyncTask. Dimension layers are also supported in mobile map packages or mobile geodatabases created in ArcGIS Pro 2.9 or later.

    Dimension respects the reference scale defined by the map, so dimension will always be presented to the user at the correct size and position, as defined by the dimension author.

    Dimension features cannot be added, changed or deleted by Runtime users. (Attempts will produce a "Geodatabase table not editable" (3016) error)

    The fields of a Dimension feature can be queried by Runtime users or used in the definition expression, but not have their values changed. The automatic fields are described in detail in "Dimension fields". Authors may have added additional fields relevant to their data description.

    The Runtime user does not have access to, and cannot change, the Renderer or the Styles used for rendering dimensions.

      • getDefinitionExpression

        public String getDefinitionExpression()
        Gets an expression which is a SQL statement where clause to specify the subset of features to be displayed.

        The definition expression string uses the SQL-92 where clause syntax The default value is an empty string, which will allow all dimension features in the data source to be used by the DimensionLayer.

        Be sure to escape special characters in the expression string as required for your platform. The DATE keyword expects the date format yyyy-mm-dd and the TIMESTAMP keyword expects the time stamp format yyyy-mm-dd hh:mm:ss. See the ArcGIS Blog article entitled "Querying Feature Services Date-Time Queries" for more information.

        Returns:
        an expression which is a SQL statement where clause to specify the subset of features to be displayed
        Since:

      • setDefinitionExpression

        public void setDefinitionExpression​(String definitionExpression)

      • getReferenceScale

        public double getReferenceScale()
        Gets the reference scale for the layer.

        The reference scale of the layer is the scale at which a client should view the layer for the schematic lines and text to appear at its authored size.

        If the client changes the viewing scale, then schematic lines and text will grow or shrink to keep a consistent size on the map (not the screen).

        For a valid layer, the reference scale will always be a finite value, greater than zero. Until the layer is loaded, the reference scale will be zero.
