Method Detail

compression

public Compression.type compression()

\brief Return the type of raw compression on the file, if any

path

@StdString
public String path()

\brief Return the file path, if any. Only valid when file source wraps a path.

filesystem

@SharedPtr
public FileSystem filesystem()

\brief Return the filesystem, if any. Otherwise returns nullptr

buffer

@Const
 @SharedPtr
 @ByRef
public ResizableBuffer buffer()

\brief Return the buffer containing the file, if any. Otherwise returns nullptr

Open

@ByVal
public OutputStreamResult Open()

\brief Get an OutputStream which wraps this file source
