Input Streams

We classify input streams by:

the source passed to their constructor
the special methods they add

The abstract superclass of all input streams is:

InputStream

+ read() : int
+ close()

Subclasses of InputStream include:

FileInputStream

+ ctor( File )
+ ctor( String )

ByteArrayInputStream

+ ctor( byte[] )

PipedInputStream

+ ctor( PipedOutputStream )
+ connect(PipedOutputStream)

SequenceInputStream

+ ctor( Enumeration )

Filter input streams take other input streams as their source:

ObjectInputStream

+ ctor(InputStream)
+ readObject() : Object

FilterInputStream

# ctor( InputStream )

Subclasses of FilterInputStream include:

BufferedInputStream

+ ctor(InputStream)

CheckedInputStream

+ ctor(InputStream, Checksum)
+ getChecksum() : Checksum

DataInputStream

+ ctor(InputStream)
+ readDouble() : double
+ readInt() : int
... and so on

PushbackInputStream

+ ctor(InputStream)
+ unread(int)

A special filter input stream is the abstract:

InflaterInputStream

+ ctor(InputStream, Inflater)

Subclasses of InflaterInputStream include:

ZipInputStream

+ ctor(InputStream)
+ getNextEntry() : ZipEntry
+ closeEntry()

JarInputStream

+ ctor(InputStream)
+ getManifest() : Manifest
