## Member Function Documentation

gcc_pure static gcc_nonnull_all string PathTraitsUTF8::Build | ( | const_pointer_type | a,
|  | size_t | a_size,
|  | const_pointer_type | b,
|  | size_t | b_size
| ) |  |
| static

Constructs the path from the given components.

If either of the components is empty string, remaining component is returned unchanged. If both components are empty strings, empty string is returned.

gcc_pure static gcc_nonnull_all const_pointer_type PathTraitsUTF8::GetBase | ( | const_pointer_type | p | ) |
| static

Determine the "base" file name of the given UTF-8 path.

The return value points inside the given string.

| inline static

Definition at line 213 of file Traits.hxx.

gcc_pure static gcc_nonnull_all string PathTraitsUTF8::GetParent | ( | const_pointer_type | p | ) |
| static

Determine the "parent" file name of the given UTF-8 path.

As a special case, returns the string "." if there is no separator in the given input string.

gcc_pure static gcc_nonnull_all const_pointer_type PathTraitsUTF8::Relative | ( | const_pointer_type | base,
|  | const_pointer_type | other
| ) |  |
| static

Determine the relative part of the given path to this object, not including the directory separator.

Returns an empty string if the given path equals this object or nullptr on mismatch.
