Mapping between Clang AST identifier and clang-uml unique ids. More...

Detailed Description

Mapping between Clang AST identifier and clang-uml unique ids.

Since identifiers provided by Clang AST are not transferable between translation units (i.e. the same class can have a different id when visited from different translation units), we need global identifiers which are the same among all translation units.

Currently they are calculated as hashes from the fully qualified string representation of the type.

This class allows to store mappings between Clang local identifiers in current translation unit and the global identifiers for the element.

◆ add()

void clanguml::common::visitor::ast_id_mapper::add	(	int64_t	ast_id,
		eid_t	global_id
	)

Add id mapping.

Parameters

ast_id	Clang's local AST id.
global_id	Global element id.

◆ get_global_id()

std::optional< eid_t > clanguml::common::visitor::ast_id_mapper::get_global_id ( eid_t ast_id )

Get global element id based on it's local Clang AST id, if exists.

Parameters

ast_id Clang's local AST id.

Returns: Global id, if exists.
