Member Function Documentation

◆ is_directory()

bool Dir_Walker::is_directory ( const Path path)
static

Check if the path is a directory.

The file/directory must exist.

Parameters
[in]pathThe path to check
Returns
true if it is a directory

◆ walk()

template<typename F >
static void Dir_Walker::walk ( const Path basedir,
bool  recursive,
F &&  f 
)
inlinestatic

Depth first traversal of the directory starting from basedir.

Parameters
[in]basedirStart scanning from this directory
[in]recursivetrue if scan should be recursive
[in]fFunction to call for each entry

◆ walk_posix()

void Dir_Walker::walk_posix ( const Path basedir,
bool  recursive,
Function &&  f 
)
staticprivate

Depth first traversal of the directory starting from basedir.

Parameters
[in]basedirStart scanning from this directory
[in]recursivetrue if scan should be recursive
[in]fCallback for each entry found
[in]basedirStart scanning from this directory
[in]recursivetrue if scan should be recursive
[in]fFunction to call for each entry
