 #### BuildMap (basic_partition_map_builder)
 
-High-level interface to build and query partition maps.
+Interface to build and query partition maps.
+
+##### Members
+- `Map_t _current_map`: Current map.
+- `std::string _workdir`: Search directory.
+- `bool _any_generating_error, _map_builded`: Status flags.
+
+##### Core Methods
+- `readDirectory(path)`: Build map from a directory.
+- `readDefaultDirectories()`: Build map from default `/dev` entries.
+- `getAll()`: Returns the current `Map_t` map.
+- `get(name)`: Returns optional info `(size, isLogical)`.
+- `getLogicalPartitionList()`, `getPhysicalPartitionList()`, `getPartitionList()`: Return partition lists.
+- `getRealLinkPathOf(name)`, `getRealPathOf(name)`: Returns path.
+- `hasPartition(name)`, `isLogical(name)`, `sizeOf(name)`, `empty()`: Info queries.
+- `copyPartitionsToVector(vec)`, `copyLogicalPartitionsToVector(vec)`, `copyPhysicalPartitionsToVector(vec)`: Copy lists to vectors.
+
+##### doFor*** Methods
+- `doForAllPartitions(func)`
+- `doForPhysicalPartitions(func)`
+- `doForLogicalPartitions(func)`
+- `doForPartitionList(list, func)`
+
+##### Operators
+- `operator*()`: Returns reference to internal map.
+- `operator std::vector<Info>()`: Returns list as vector<Info>.
+- `operator int()`: Returns partition count.
+- `operator std::string()`: Returns working directory.
+- `operator bool()`: Success check.
+- `operator!()`: Failure check.
+- `operator()(path)`: Build map from path.
