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 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

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.
