Map return type. Type of data to return when selecting or removing items from the map.

Variants

None

Do not return a result.

Index

Return key index order.

• 0 = first key
• N = Nth key
• -1 = last key

ReverseIndex

Return reverse key order.

• 0 = last key
• -1 = first key

Rank

Return value order.

• 0 = smallest value
• N = Nth smallest value
• -1 = largest value

ReverseRank

Return reserve value order.

• 0 = largest value
• N = Nth largest value
• -1 = smallest value

Count

Return count of items selected.

Key

Return key for single key read and key list for range read.

Value

Return value for single key read and value list for range read.

KeyValue

Return key/value items. The possible return types are:

• Value::HashMap: Returned for unordered maps
• Value::OrderedMap: Returned for range results where range order needs to be preserved.

Inverted

Invert meaning of map command and return values. With the INVERTED flag enabled, the keys outside of the specified key range will be removed and returned.
