Constructor & Destructor Documentation

TreeNode()

tiny_dlna::TreeNode::TreeNode ( )

default

Member Function Documentation

addMimeRule()

static void tiny_dlna::TreeNode::addMimeRule ( const std::string &  ext, const std::string &  mime  )

inlinestatic

Add one MIME rule mapping extension -> MIME type.

getMime()

std::string tiny_dlna::TreeNode::getMime ( ) const

inline

Very basic MIME inference based on file extension.

Returns

A MIME type string for known audio formats, or empty string if unknown or directory.

level()

int tiny_dlna::TreeNode::level ( ) const

inline

Returns the nesting level from the root.

Returns

0 for the root, otherwise number of parents to reach the root.

operator delete()

static void tiny_dlna::TreeNode::operator delete ( void *  ptr )

inlinestatic

operator new()

static void * tiny_dlna::TreeNode::operator new ( std::size_t  size )

inlinestatic

path()

std::string tiny_dlna::TreeNode::path ( ) const

inline

Computes the full path from the root to this node.

Returns

Path string where directory components are separated by '/'.

setMimeRules()

static void tiny_dlna::TreeNode::setMimeRules ( const std::vector< std::pair< std::string, std::string > > &  rules )

inlinestatic

Replace all MIME rules.

Extensions are matched case-insensitively against the file name and should include the leading dot (e.g. ".mp3"). If provided without a dot or with uppercase letters, they will be normalized.
