All Implemented Interfaces:

Closeable, Flushable, Appendable

Direct Known Subclasses:

StringBufferPrintStream, VT100PrintStream

public abstract class AbstractPrintStream
extends PrintStream

Abstracts the minimal implementation methods by extension of PrintStream.
Implementing a customized PrintStream requires the implementation of the following methods:

• write(int), and
• write(byte[], int, int)

Method Detail

write

public abstract void write(int b)

Overrides:

write in class PrintStream

write

public abstract void write(byte[] buf,
                           int off,

Overrides:

write in class PrintStream

_write

protected void _write(int b)

Use this method to delegate calls to those with similar signature from PrintStream. e.g. in situations where data is gathered on output, or other output is prepended or appended.
