public class ByteVector
extends Object

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

Constructor Details

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 Details

putByte

public ByteVector putByte(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.

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.

putInt

public ByteVector putInt(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.

putLong

public ByteVector putLong(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.

putShort

public ByteVector putShort(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.

putUTF8

public ByteVector putUTF8(String s)
Puts an UTF8 string into this byte vector. The byte vector is automatically enlarged if necessary.
Parameters:
s - a String.
Returns:
this byte vector.
