This interface defines a WeakMap<string, object>. It allows storing and retrieving objects using a string key. Internally, objects are weakly referenced (using cl_abap_weak_reference) and may be garbage collected if no strong references exist elsewhere in the system.
Returns NULL if no mapping exists or if the object has been garbage collected.
keyThe string key associated with the object.
resultThe referenced object, or NULL if not available.
METHODS get IMPORTING !key TYPE string
RETURNING VALUE(result) TYPE REF TO object.If a mapping for the key already exists, it will be overwritten.
keyThe string key to associate with the object.
objThe object reference to store (may be NULL).
METHODS set IMPORTING !key TYPE string
obj TYPE REF TO object.Returns true if a mapping was removed, false otherwise.
keyThe string key of the mapping to remove.
resulttrue if removal was successful, false otherwise.
