Map Bin Operations
Map expressions is a system for calling CDT Map operations. These expressions return bins that can be used in other expressions that take a bin_expr parameter.
Map Modify Operations
Map_modify expressions differ from CDT Map operations in that they return the modified bin instead of a specified return type (for remove_by ops) or predefined return type (The CDT operation put returns an int for example).
map_clear
Introduced: 5.2.0.4
map_clear(context, bin)
Clear all elements in map bin.

Increment element at key by delta.
- context (library_specific)

map_put
Introduced: 5.2.0.4
map_put(context, policy, key, value, bin)

map_put_items
Introduced: 5.2.0.4

Map Read Operations
Map_read expressions (other than MAP_SIZE) return a result based on their integer_value parameter. Calling single result CDT operations (e.g. MAP_GET_BY_INDEX) requires an integer_value when integer_value is MAP_RETURN_KEY or MAP_RETURN_VALUE as a map key or value can be any expression type.
