Detailed Description

Provides a default savefile manager implementation for common platforms.

Member Function Documentation

updateSavefilesList()

void DefaultSaveFileManager::updateSavefilesList ( Common::StringArray &  lockedFiles )

overridevirtual

Refresh the save files list (because some new files might have been added) and remember the "locked" files list. These files cannot be used for saving or loading because they are being synced by CloudManager.

Implements Common::SaveFileManager.

listSavefiles()

Common::StringArray DefaultSaveFileManager::listSavefiles ( const Common::String &  pattern )

overridevirtual

List available save files matching a given pattern.

The pattern format is based on DOS patterns, also known as "glob" in the POSIX world. Refer to the Common::matchString() function for information about the precise pattern format.

Parameters

pattern

Pattern to match. Wildcards like * or ? are allowed.

Returns

List of strings for all present file names.

Common::matchString()

Implements Common::SaveFileManager.

openRawFile()

Common::InSaveFile* DefaultSaveFileManager::openRawFile ( const Common::String &  name )

overridevirtual

Open the file with the specified name in the given directory for loading. In contrast to openForLoading(), it returns a raw file instead of unpacked.

Parameters

name	Name of the save file.

Returns

Pointer to an InSaveFile, or NULL if an error occurred.

Implements Common::SaveFileManager.

openForLoading()

Common::InSaveFile* DefaultSaveFileManager::openForLoading ( const Common::String &  name )

overridevirtual

Open the file with the specified name in the given directory for loading.

Parameters

name	Name of the save file.

Returns

Pointer to an InSaveFile, or NULL if an error occurred.

Implements Common::SaveFileManager.

openForSaving()

Common::OutSaveFile* DefaultSaveFileManager::openForSaving ( const Common::String &  name, bool  compress = true  )

overridevirtual

Open the save file with the specified name in the given directory for saving.

Saved games are compressed by default, and engines are expected to always write compressed saves.

A notable exception is when uncompressed files are needed for compatibility with games not supported by ScummVM, such as character exports from the Quest for Glory series. QfG5 is a 3D game and will not be supported by ScummVM.

Parameters

name	Name of the save file.
compress	Whether to compress the resulting save file (default) or not.

Returns

Pointer to an OutSaveFile, or NULL if an error occurred.

Implements Common::SaveFileManager.

removeSavefile()

bool DefaultSaveFileManager::removeSavefile ( const Common::String &  name )

overridevirtual

Remove the given save file from the system.

Parameters

name	Name of the save file to be removed.

Returns

True if no error occurred, false otherwise.

Implements Common::SaveFileManager.

exists()

bool DefaultSaveFileManager::exists ( const Common::String &  name )

overridevirtual

Checks if the savefile exists.

Parameters

name	Name of the save file.

Returns

true if the file exists. false otherwise.

Implements Common::SaveFileManager.

getSavePath()

virtual Common::Path DefaultSaveFileManager::getSavePath ( ) const

protectedvirtual

Get the path to the savegame directory. Should only be used internally since some platforms might implement savefiles in a completely different way.

checkPath()

virtual void DefaultSaveFileManager::checkPath ( const Common::FSNode &  dir )

protectedvirtual

Checks the given path for read access, existence, etc. Sets the internal error and error message accordingly.

removeFile()

virtual Common::ErrorCode DefaultSaveFileManager::removeFile ( const Common::FSNode &  fileNode )

protectedvirtual

Removes the given file. This is called from removeSavefile() with the full file path.

Reimplemented in WindowsSaveFileManager.

assureCached()

void DefaultSaveFileManager::assureCached ( const Common::Path &  savePathName )

protected

Assure that the given save path is cached.

Parameters

savePathName

String representation of save path to cache.

Member Data Documentation

_saveFileCache

SaveFileCache DefaultSaveFileManager::_saveFileCache

protected

Cache of all the save files in the currently cached directory.

Modify with caution because we only re-cache when the save path changed! This needs to be updated inside at least openForSaving and removeSavefile.

_lockedFiles

Common::StringArray DefaultSaveFileManager::_lockedFiles

protected

List of "locked" files. These cannot be used for saving/loading because CloudManager is downloading those.
