createDirectory()

void fs::createDirectory

(

const std::string &

dir

)

Definition at line 69 of file Filesystem.cxx.

{ LOG(LOG_ERROR) << "fs::createDirectory() not implemented!"; }

Here is the caller graph for this function:

fileExists()

bool fs::fileExists

(

const std::string &

filePath

)

Check if a file (or folder) exists.

Parameters

filePath

Path to file or folder to check

Returns

true if the path exists

Definition at line 62 of file Filesystem.cxx.

{ return true; }

Here is the caller graph for this function:

getBasePath()

std::string fs::getBasePath

(

)

Get base path (where Cytopia is being run)

A wrapper for SDL_GetBasePath, which is not run on Android because it hard-crashes the app. Memory is freed after the call.

Returns

the Base path

Definition at line 77 of file Filesystem.cxx.

{ return ""; }

Here is the caller graph for this function:

getDirectoryListing()

std::vector<std::string> fs::getDirectoryListing

(

const std::string &

directory

)

Get a directory listing of a given directory.

Parameters

directory

Name of the folder to retrieve the directory listing from

Returns

a directory::iterator containing the folder content

Definition at line 55 of file Filesystem.cxx.

{
  LOG(LOG_ERROR) << "fs::getDirectoryListing() not implemented!";
}

getSaveGamePaths()

std::vector<std::string> fs::getSaveGamePaths

(

)

Get all savegames in the savegame directory.

Returns

a std::vector containing paths with all savegames

Definition at line 60 of file Filesystem.cxx.

{ LOG(LOG_ERROR) << "fs::getSaveGamePaths() not implemented!"; }

readCompressedFileAsString()

std::string fs::readCompressedFileAsString

(

const std::string &

fileName

)

Read contents from a file as string.

Parameters

fileName	Name of the file to read
binaryMode	(optional) open the file in binary mode. (default: false)

Returns

the content of the file as string
