Procedures

• Add(Instance: Codeunit "BOM Tree Node") (internal): Adds an instance to the dictionary. The key is fetched from the GetKey() procedure of the Instance implementation. The instance to add. In case there is another instance with a key same as the one being added, an error shall be raised.
• TryAdd(Instance: Codeunit "BOM Tree Node") (internal): Adds an instance to the dictionary by calling the Add() procedure in a TryFunction. The instance to add.
• Get(InstanceKey: Text; var Found: Codeunit "BOM Tree Node") (internal): Fetches the instance based on the given key. The key given. The instance that was fetched.
• TryGet(UniqueKey: Text; var Found: Codeunit "BOM Tree Node") (internal): Fetches the instance based on the given key by calling the Get() procedure in a TryFunction. The key given. The instance that was fetched.
• ContainsKey(InstanceKey: Text): Boolean + BC28 (internal): Checks whether an instance with the given key exists in the dictionary without raising an error. The key given.
• Remove(InstanceKey: Text): Removes the instance from the dictionary that correponds to the given key. The given key.
• ResetEnumerator(): Resets the internal variables that allow iterating through the items in the dictionary. It is a good practice to call this before starting an iteration.
• MoveNext(): Boolean: Advances the enumerator to the next element of the dictionary.
• GetCurrent(var Instance: Codeunit "BOM Tree Node") (internal): Gets the element in the dictionary at the current position of the enumerator. The instance pointed at.
• Count(): Integer: Gets the number of items in the dictionary.

Calls

From the extracted call graph of BC29 (graphify-al on the snapshot checkout): calls whose target is known from a declared type or an Object::"Name" argument. Interface dispatch and calls through events are not counted, so the list is not complete.

Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC29 call graph. For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: bcatlas_resolve_node(object_type: "codeunit", object_name: "BOM Tree Node Dictionary"), then bcatlas_get_procedure_body or bcatlas_get_neighbors on the returned id.
