Class PathImageInputStream

java.lang.Object

javax.imageio.stream.ImageInputStreamImpl

is.galia.stream.PathImageInputStream

All Implemented Interfaces:

Closeable, DataInput, AutoCloseable, ImageInputStream

public class PathImageInputStream
extends ImageInputStreamImpl
implements ImageInputStream

Analog of FileImageInputStream that uses Paths instead of Files.

Also, unlike FileImageInputStream which is backed by a RandomAccessFile, this implementation is backed by a faster buffered implementation.

Constructor Details

PathImageInputStream

public PathImageInputStream(Path path)
                     throws IOException

Constructs an instance that will read from a given Path.

The file contents must not change between the time this object is constructed and the time of the last call to a read method.

Parameters:

path - Path to read from.

Throws:

NoSuchFileException - if path is a directory or cannot be opened for reading for any other reason.

IOException - if an I/O error occurs.
