Class ByteVector

  • 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​(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.

      • 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.

      • 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.

      • 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 whose UTF8 encoded length must be less than 65536.
        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.
