cryptix.openpgp.io
Class PGPDataOutputStream  

java.lang.Object
  cryptix.openpgp.io.PGPDataOutputStream

Direct Known Subclasses:

PGPByteArrayDataOutputStream, PGPChecksumDataOutputStream, PGPLengthDataOutputStream, PGPWrapperDataOutputStream

---

public abstract class PGPDataOutputStream

extends java.lang.Object

Generic superclass for all outputstreams

This class contains the basic methods for outputstreams. A subclass only has to implement the writeInternal and close methods and then all the other methods here will magically work.

Version:

$Revision: 1.2 $

Method Detail

writeInternal

protected abstract void writeInternal(int b)
                               throws java.io.IOException

Internal method used by all other methods to write one byte.

---

close

public abstract void close()
                    throws java.io.IOException

Close this inputstream

---

writeBoolean

public void writeBoolean(boolean x)
                  throws java.io.IOException

Write a boolean

---

writeByte

public void writeByte(byte x)
               throws java.io.IOException

Write a byte

---

writeShort

public void writeShort(short x)
                throws java.io.IOException

Write a short

---

writeInt

public void writeInt(int x)
              throws java.io.IOException

Write an int

---

writeLong

public void writeLong(long x)
               throws java.io.IOException

Write a long

---

writeFully

public void writeFully(byte[] b)
                throws java.io.IOException

Write an array of bytes

The complete array is written, calling this method is equivalent to writeFully(b, 0, b.length);

---

writeFully

public void writeFully(byte[] b,
                       int offset,
                       int len)
                throws java.io.IOException

Write an array of bytes

Writing starts at offset and continues for len bytes.

---

writeString

public void writeString(java.lang.String x)
                 throws java.io.IOException

Write a string

This method writes a string in UTF-8 encoding.

---

writeNullTerminatedString

public void writeNullTerminatedString(java.lang.String x)
                               throws java.io.IOException

Write a null terminated string

This method simply calls writeString and then writes a null byte.

---

writeLengthPrependedString

public void writeLengthPrependedString(java.lang.String x)
                                throws java.io.IOException

Write a string with a length byte prepended

---

writeMPI

public void writeMPI(java.math.BigInteger x)
              throws java.io.IOException

Write a PGP encoded multi-precision-integer (MPI)

This method uses the cryptix.openpgp.util.PGPMPI class to write an MPI.
