abstract class GeoMesaFeatureIndex[T, U] extends NamedIndex with LazyLogging

Represents a particular indexing strategy

T

values extracted from a filter and used for creating ranges - extracted geometries, z-ranges, etc

U

a single key space index value, e.g. Long for a z-value, etc

Instance Constructors

  1. new GeoMesaFeatureIndex(ds: GeoMesaDataStore[_], sft: SimpleFeatureType, name: String, version: Int, attributes: Seq[String], mode: IndexMode)

    ds

    data store

    sft

    simple feature type stored in this index

    name

    name of the index

    version

    version of the index

    attributes

Abstract Value Members

  1. abstract def getFilterStrategy(filter: Filter, transform: Option[SimpleFeatureType]): Option[FilterStrategy]

    Gets options for a 'simple' filter, where each OR is on a single attribute, e.g.

    Gets options for a 'simple' filter, where each OR is on a single attribute, e.g. (bbox1 OR bbox2) AND dtg bbox AND dtg AND (attr = foo OR attr = bar) not: bbox OR dtg

    Because the input is simple, it can be satisfied with a single query filter.

    filter

    input filter

    transform

    attribute transforms

    returns

    a filter strategy which can satisfy the query, if available

  2. abstract def keySpace: IndexKeySpace[T, U]

    Primary key space used by this index

  3. abstract def tieredKeySpace: Option[IndexKeySpace[_, _]]

    Tiered key space beyond the primary one, if any
