Class ByteVector

java.lang.Object
com.googlecode.aviator.asm.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.

  • Field Details

    • data

      byte[] data
      The content of this vector.

    • length

      int length
      Actual number of bytes in this vector.

  • 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.

    • put11

      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.

    • 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.

    • put12

      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.

    • 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.
      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.
