Class ByteVector

java.lang.Object
  org.logicalcobwebs.asm.ByteVector

final class ByteVector
extends java.lang.Object

A dynamically extensible vector of bytes. This class is roughly equivalent to a DataOutputStream on top of a ByteArrayOutputStream, but is more efficient.

Field Summary

(package private) byte[]	data The content of this vector.
(package private) int	length Actual number of bytes in this vector.

Constructor Summary

ByteVector()
Constructs a new ByteVector with a default initial size.

ByteVector(int initialSize)
Constructs a new ByteVector with the given initial size.

Method Summary

private void	enlarge(int size) Enlarge this byte vector so that it can receive n more bytes.
ByteVector	put1(int b) Puts a byte into this byte vector.
ByteVector	put11(int b1, int b2) Puts two bytes into this byte vector.
ByteVector	put12(int b, int s) Puts a byte and a short into this byte vector.
ByteVector	put2(int s) Puts a short into this byte vector.
ByteVector	put4(int i) Puts an int into this byte vector.
ByteVector	put8(long l) Puts a long into this byte vector.
ByteVector	putByteArray(byte[] b, int off, int len) Puts an array of bytes into this byte vector.
ByteVector	putUTF(java.lang.String s) Puts a String in UTF format into this byte vector.

Constructor Detail

ByteVector

public ByteVector()

Constructs a new ByteVector with a default initial size.

ByteVector

public ByteVector(int initialSize)

Constructs a new ByteVector with the given initial size.

Parameters:

initialSize - the initial size of the byte vector to be constructed.

Method Detail

put1

public ByteVector put1(int b)

Puts a byte into this byte vector. The byte vector is automatically enlarged if necessary.

Parameters:

b - a byte.

Returns:

this byte vector.

put11

public ByteVector put11(int b1,
                        int b2)

Puts two bytes into this byte vector. The byte vector is automatically enlarged if necessary.

Parameters:

b1 - a byte.

b2 - another byte.

Returns:

this byte vector.

put2

public ByteVector put2(int s)

Puts a short into this byte vector. The byte vector is automatically enlarged if necessary.

Parameters:

s - a short.

Returns:

this byte vector.

put12

public ByteVector put12(int b,
                        int s)

Puts a byte and a short into this byte vector. The byte vector is automatically enlarged if necessary.

Parameters:

b - a byte.

s - a short.

Returns:

this byte vector.

put4

public ByteVector put4(int i)

Puts an int into this byte vector. The byte vector is automatically enlarged if necessary.

Parameters:

i - an int.

Returns:

this byte vector.

put8

public ByteVector put8(long l)

Puts a long into this byte vector. The byte vector is automatically enlarged if necessary.

Parameters:

l - a long.

Returns:

this byte vector.

putUTF

public ByteVector putUTF(java.lang.String s)

Puts a String in UTF format into this byte vector. The byte vector is automatically enlarged if necessary.

Parameters:

s - a String.

Returns:

this byte vector.

putByteArray

public ByteVector putByteArray(byte[] b,
                               int off,
                               int len)

Puts an array of bytes into this byte vector. The byte vector is automatically enlarged if necessary.

Parameters:

b - an array of bytes. May be null to put len null bytes into this byte vector.

off - index of the fist byte of b that must be copied.

len - number of bytes of b that must be copied.

Returns:

this byte vector.

enlarge

private void enlarge(int size)

Enlarge this byte vector so that it can receive n more bytes.

Parameters:

size - number of additional bytes that this byte vector should be able to receive.
