Example 1 with TemporalFieldDescriptorBuilder

use of org.locationtech.geowave.core.geotime.adapter.TemporalFieldDescriptorBuilder in project geowave by locationtech.

the class FeatureDataAdapter method initializeFieldDescriptors.

private void initializeFieldDescriptors() {
    final List<AttributeDescriptor> attributes = featureType.getAttributeDescriptors();
    fieldDescriptors = new FieldDescriptor[attributes.size()];
    for (int i = 0; i < attributes.size(); i++) {

        if (attribute instanceof GeometryDescriptor) {
            final SpatialFieldDescriptorBuilder<?> builder = new SpatialFieldDescriptorBuilder<>(attribute.getType().getBinding());
            builder.fieldName(attribute.getName().getLocalPart());
            builder.crs(((GeometryDescriptor) attribute).getCoordinateReferenceSystem());
            if ((featureType.getGeometryDescriptor() != null) && featureType.getGeometryDescriptor().equals(attribute)) {
                builder.spatialIndexHint();

    // this assumes attribute names are unique, which *should* be a fair assumption
    descriptorsMap = Arrays.stream(fieldDescriptors).collect(Collectors.toMap(FieldDescriptor::fieldName, descriptor -> descriptor));
}

Example 2 with TemporalFieldDescriptorBuilder

use of org.locationtech.geowave.core.geotime.adapter.TemporalFieldDescriptorBuilder in project geowave by locationtech.
