Example 1 with DataIndexReaderParams

use of org.locationtech.geowave.core.store.operations.DataIndexReaderParams in project geowave by locationtech.

the class DataIndexUtils method delete.

    // IDs to be non-null within reader params and deletions don't have logic for handling ranges
    // for now, although less efficient, let's query by prefix and then delete by the returned IDs
