Detailed Description

The DynamicLayer class extends a Layer to be able to express itself as several Layers. Each of these 'sub-layers' is defined by adding filters to the original layer. The filters are configured in the LayerConfig class, on a set of nodes related to the original dynamic layer node by LAYER_CONFIG relationships. One key example of where this type of capability is very valuable is for example when a layer contains geometries of multiple types, but geotools can only express one type in each layer. Then we can use DynamicLayer to expose each of the different geometry types as a different layer to the consuming application (desktop or web application). DynamicLayer extends EdiableLayerImpl, and is therefore editable. Not that this support is dependant on the correct working of the appropriate GeometryEncoder, and also does not extend to the sub-layers provided. Those are read-only views.

Each dataset can have one or more layers. This methods provides a way to iterate over all layers.

Returns
iterable over all Layers that can be viewed from this dataset

Implements Neo4jSpatiotemporal.SpatialTemporalDataset.

boolean Neo4jSpatiotemporal.DynamicLayerTemporal.removeLayerConfig ( String  name)
protected
DynamicLayerConfigTemporal Neo4jSpatiotemporal.DynamicLayerTemporal.restrictLayerProperties ( String  name,
String[]  names 
)

Restrict specified layers attributes to the specified set. This will simply save the quest to the LayerConfig node, so that future queries will only return attributes that are within the named list. If you want to have it perform and automatic search, pass null for the names list, but be warned, this can take a long time on large datasets.

Parameters
nameof layer to restrict
namesto use for attributes
Returns
DynamicLayerConfigTemporal Neo4jSpatiotemporal.DynamicLayerTemporal.restrictLayerProperties ( String  name)

Restrict specified layers attributes to only those that are actually found to be used. This does an exhaustive search and can be time consuming. For large layers, consider manually setting the properties instead.

Parameters
name
Returns
