H2ScanIndex (Ignite 8.9.14-p2)

java.lang.Object
- org.gridgain.internal.h2.engine.DbObjectBase
- - org.gridgain.internal.h2.schema.SchemaObjectBase
  - - org.gridgain.internal.h2.index.BaseIndex
    - - org.apache.ignite.internal.processors.query.h2.opt.H2ScanIndex<D>

All Implemented Interfaces:

org.gridgain.internal.h2.engine.DbObject, org.gridgain.internal.h2.index.Index, org.gridgain.internal.h2.schema.SchemaObject

Direct Known Subclasses:

H2TableScanIndex
```
public class H2ScanIndex<D extends org.gridgain.internal.h2.index.BaseIndex>
extends org.gridgain.internal.h2.index.BaseIndex
```
Scan index. Do not actually store any information, but rather delegate to some underlying index. The only reason why this index exists is H2 requirement that every table must have the very first index with IndexType.isScan() set to true. See TYPE.
