Module aerospike::operations::maps

Unique key map bin operations. Create map operations used by the client's operate() method.

All maps maintain an index and a rank. The index is the item offset from the start of the map, for both unordered and ordered maps. The rank is the sorted index of the value component. Map supports negative indexing for indexjkj and rank.

The default unique key map is unordered.

Index/Count examples:

• Index 0: First item in map.
• Index 4: Fifth item in map.
• Index -1: Last item in map.
• Index -3: Third to last item in map.
• Index 1, Count 2: Second and third items in map.
• Index -3, Count 3: Last three items in map.
• Index -5, Count 4: Range between fifth to last item to second to last item inclusive.

Rank examples:

• Rank 0: Item with lowest value rank in map.
• Rank 4: Fifth lowest ranked item in map.
• Rank -1: Item with highest ranked value in map.
• Rank -3: Item with third highest ranked value in map.
• Rank 1 Count 2: Second and third lowest ranked items in map.
• Rank -3 Count 3: Top three ranked items in map.

Structs

MapPolicy

MapPolicy directives when creating a map and writing map items.

Enums

MapOrder	Map storage order.
MapReturnType	Map return type. Type of data to return when selecting or removing items from the map.
MapWriteMode	Unique key map write type.

Functions

clear	Create map clear operation. Server removes all items in the map. Server does not return a result.
decrement_value	Create map decrement operation. Server decrements values by decr for all items identified by the key and returns the final result. Valid only for numbers.
get_by_index	Create map get by index operation. Server selects the map item identified by index and returns the selected data specified by return_type.
get_by_index_range	Create map get by index range operation. Server selects count map items starting at the specified index and returns the selected data specified by return_type.
get_by_index_range_from	Create map get by index range operation. Server selects the map items starting at the specified index to the end of the map and returns the selected data specified by return_type.
get_by_key	Create map get by key operation. Server selects the map item idenfieid by the key and returns the selected data specified by return_type.
get_by_key_range	Create map get by key range operation. Server selects the map items identified by the key range (begin inclusive, end exclusive). If begin is Value::Nil, the range is less than end. If end is Value::Nil the range is greater than equal to begin. Server returns the selected data specified by return_type.
get_by_rank	Create map get by rank operation. Server selects the mamp item identified by rank and returns the selected data specified by return_type.
get_by_rank_range	Create map get ranke range operation. Server selects count map items at the specified rank and returns the selected data specified by return_type.
get_by_rank_range_from	Create map get by rank range operation. Server selects the map items starting at the specified rank to the last ranked item and returns the selected data specified by return_type.
get_by_value	Create map get by value operation. Server selects the map items identified by value and returns the selected data specified by return_type.
get_by_value_range	Create map get by value range operation. Server selects the map items identified by the value range (begin inclusive, end exclusive). If begin is Value::Nil, the range is less than end. If end is Value::Nil, the range is greater than equal to begin. Server returns the selected data specified by return_type.
increment_value	Create map increment operation. Server increments values by incr for all items identified by the key and returns the final result. Valid only for numbers.
put_item	Create map put operation. Server writes the key/value item to the map bin and returns the map size.
put_items	Create map put items operation. Server writes each map item to the map bin and returns the map size.
remove_by_index	Create map remove operation. Server removes the map item identified by the index and return the removed data specified by return_type.
remove_by_index_range	Create map remove operation. Server removes count map items starting at the specified index and returns the removed data specified by return_type.
remove_by_index_range_from	Create map remove operation. Server removes the map items starting at the specified index to the end of the map and returns the removed data specified by return_type.
remove_by_key	Create map remove operation. Server removes the map item identified by the key and returns the removed data specified by return_type.
remove_by_key_list	Create map remove operation. Server removes map items identified by keys and returns removed data specified by return_type.
remove_by_key_range	Create map remove operation. Server removes map items identified by the key range (begin inclusive, end exclusive). If begin is Value::Nil, the range is less than end. If end is Value::Nil, the range is greater than equal to begin. Server returns removed data specified by return_type.
remove_by_rank	Create map remove operation. Server removes the map item identified by rank and returns the removed data specified by return_type.
remove_by_rank_range	Create map remove operation. Server removes count map items starting at the specified rank and returns the removed data specified by return_type.
remove_by_rank_range_from	Create map remove operation. Server removes the map items starting at the specified rank to the last ranked item and returns the removed data specified by return_type.
remove_by_value	Create map remove operation. Server removes the map items identified by value and returns the removed data specified by return_type.
remove_by_value_list	Create map remove operation. Server removes the map items identified by values and returns the removed data specified by return_type.
remove_by_value_range	Create map remove operation. Server removes map items identified by value range (begin inclusive, end exclusive). If begin is Value::Nil, the range is less than end. If end is Value::Nil, the range is greater than equal to begin. Server returns the removed data specified by return_type.
set_order	Create set map policy operation. Server set the map policy attributes. Server does not return a result.
