Output Streams

We classify output streams by:

the sink passed to their constructor
the special methods they add

The abstract superclass of all output streams is:

OutputStream

+ write(int)
+ flush()
+ close()

Subclasses of OutputStream include:

ByteArrayOutputStream

+ ctor()
+ toByteArray() : byte[]

FileOutputStream

+ ctor( File )
+ ctor( String )

PipedOutputStream

+ ctor( PipedInputStream )
+ connect(PipedInputStream)

Filter output streams take other output streams as their sink:

ObjectOutputStream

+ ctor(OutputStream)
+ writeObject(Object)

FilterOutputStream

+ ctor(OutputStream)

Subclasses of FilterOutputStream include:

BufferedOutputStream

+ ctor(OutputStream)

DataOutputStream

+ ctor(OutputStream)
+ write(int)
+ writeDouble(double)
... and so on

PrintStream

+ ctor(OutputStream)
+ print(Object or primitive)
+ println(Object or primitive)

A special filter output stream is the abstract:

DeflaterOutputStream

+ ctor(OutputStream)

Subclasses of DeflaterOutputStream include:

ZipOutputStream

+ ctor(OutputStream)
+ putNextEntry(ZipEntry)
+ closeEntry()

JarOutputStream

+ ctor(OutputStream, Manifest)
+ putNextEntry(ZipEntry)
