|---|---|
java.nio.ByteBuffer |
getIndexedValue(java.nio.ByteBuffer partitionKey,
Clustering<?> clustering,
CellPath path,
java.nio.ByteBuffer cellValue)
Extract the value to be inserted into the index from the components of the base data

boolean |
isStale(Row data,
java.nio.ByteBuffer indexValue,
int nowInSec)
Check whether a value retrieved from an index is still valid by comparing it to current row from the base table.
|
boolean |
supportsOperator(ColumnMetadata indexedColumn,
Operator operator)
Returns true if an index of this type can support search predicates of the form [column] OPERATOR [value]
