Class ByteVector

java.lang.Object
org.eclipse.sisu.space.asm.ByteVector

final 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 whose UTF8 encoded length must be less than 65536.
      Returns:
      this byte vector.
    • encodeUTF8

      ByteVector encodeUTF8(String s, int i, int maxByteLength)
      Puts an UTF8 string into this byte vector. The byte vector is automatically enlarged if necessary. The string length is encoded in two bytes before the encoded characters, if there is space for that (i.e. if this.length - i - 2 >= 0).
      Parameters:
      s - the String to encode.
      i - the index of the first character to encode. The previous characters are supposed to have already been encoded, using only one byte per character.
      maxByteLength - the maximum byte length of the encoded string, including the already encoded characters.
      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.
