Member Function Documentation

VfsFile * VfsDirectory::AddFile

(

const VfsFile &

file

)

Returns

address of existing or newly inserted file.

VfsDirectory * VfsDirectory::AddSubdirectory

(

const VfsPath &

name

)

Returns

address of existing or newly inserted subdirectory.

const PRealDirectory& VfsDirectory::AssociatedDirectory ( ) const

inline

void VfsDirectory::Clear

(

)

empty file and subdirectory lists (e.g.

when rebuilding VFS). CAUTION: this invalidates all previously returned pointers.

void VfsDirectory::DeleteSubtree

(

const VfsFile &

file

)

remove the given file or subdirectory according to the priority of the passed .DELETED file.

CAUTION: Invalidates all previously returned pointers of the file or subdirectory (and contents) if those have lower priority than file.

bool VfsDirectory::DeleteTree ( const VfsFile &  file )

private

remove all files with a lower priority than file and do the same for all subdirectories recursively.

Returns

true if the directory is empty afterwards

const VfsFiles& VfsDirectory::Files ( ) const

inline

VfsFile * VfsDirectory::GetFile

(

const VfsPath &

name

)

Returns

file with the given name. (note: non-const to allow changes to the file)

VfsDirectory * VfsDirectory::GetSubdirectory

(

const VfsPath &

name

)

Returns

subdirectory with the given name. (note: non-const to allow changes to the subdirectory)

void VfsDirectory::RemoveFile

(

const VfsPath &

name

)

remove the given file from the virtual directory (no effect on the physical file).

no effect if the file does not exist.

void VfsDirectory::RequestRepopulate

(

)

ensure the next ShouldPopulate returns true.

void VfsDirectory::SetAssociatedDirectory

(

const PRealDirectory &

realDirectory

)

side effect: the next ShouldPopulate() will return true.

bool VfsDirectory::ShouldPopulate

(

)

Returns

whether this directory should be populated from its AssociatedDirectory(). note that calling this is a promise to do so if true is returned – the flag is reset immediately.

const VfsSubdirectories& VfsDirectory::Subdirectories ( ) const

inline
