Member Typedef Documentation

Function

using Dir_Walker::Function = std::function<void(const Path &, size_t)>

private

Path

using Dir_Walker::Path = std::string

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]

path

The 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]	basedir	Start scanning from this directory
[in]	recursive	true if scan should be recursive
[in]	f	Function 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]	basedir	Start scanning from this directory
[in]	recursive	true if scan should be recursive
[in]	f	Function to call for each entry
