The new BoundedInputStream wraps a new BufferedInputStream.

Parameters:

file - The file.

Returns:

a new BoundedInputStream

Throws:

IOException - if an I/O error occurs

newBoundedInputStream

private static BoundedInputStream newBoundedInputStream(FileInputStream fileInputStream)
                                                 throws IOException

Throws:

IOException

newBoundedInputStream

                                         throws IOException

Throws:

IOException

newBoundedInputStream

static BoundedInputStream newBoundedInputStream(Path path)
                                         throws IOException

Creates a new BoundedInputStream bound by the size of the given path.

The new BoundedInputStream wraps a new BufferedInputStream.

Parameters:

path - The path.

Returns:

a new BoundedInputStream

Throws:

IOException - if an I/O error occurs

newBoundedInputStream

static BoundedInputStream newBoundedInputStream(String first,
 String... more)
                                         throws IOException

Creates a new BoundedInputStream bound by the size of the given file.

The new BoundedInputStream wraps a new BufferedInputStream.

Parameters:

first - the path string or initial part of the path string.

more - additional strings to be joined to form the path string.

Returns:

a new BoundedInputStream

Throws:

IOException - if an I/O error occurs

newBoundedInputStream

static BoundedInputStream newBoundedInputStream(URL url)
                                         throws IOException,
