Class ByteVector

java.lang.Object
org.eclipse.persistence.internal.libraries.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.

  • Constructor Details

    • ByteVector

      public ByteVector()
      Constructs a new ByteVector with a default initial capacity.

    • ByteVector

      public ByteVector(int initialCapacity)
      Constructs a new ByteVector with the given initial capacity.
      Parameters:
      initialCapacity - the initial capacity of the byte vector to be constructed.

  • Method Details

    • size

      public int size()
      Returns the actual number of bytes in this vector.
      Returns:
      the actual number of bytes in this vector.

    • putByte

      public ByteVector putByte(int byteValue)
      Puts a byte into this byte vector. The byte vector is automatically enlarged if necessary.
      Parameters:
      byteValue - a byte.
      Returns:
      this byte vector.

    • putShort

      public ByteVector putShort(int shortValue)
      Puts a short into this byte vector. The byte vector is automatically enlarged if necessary.
      Parameters:
      shortValue - a short.
      Returns:
      this byte vector.

    • putInt

      public ByteVector putInt(int intValue)
      Puts an int into this byte vector. The byte vector is automatically enlarged if necessary.
      Parameters:
      intValue - an int.
      Returns:
      this byte vector.

    • putLong

      public ByteVector putLong(long longValue)
      Puts a long into this byte vector. The byte vector is automatically enlarged if necessary.
      Parameters:
      longValue - a long.
      Returns:
      this byte vector.

    • putUTF8

      public ByteVector putUTF8(String stringValue)
      Puts an UTF8 string into this byte vector. The byte vector is automatically enlarged if necessary.
      Parameters:
      stringValue - a String whose UTF8 encoded length must be less than 65536.
      Returns:
      this byte vector.

    • putByteArray

      public ByteVector putByteArray(byte[] byteArrayValue, int byteOffset, int byteLength)
      Puts an array of bytes into this byte vector. The byte vector is automatically enlarged if necessary.
      Parameters:
      byteArrayValue - an array of bytes. May be null to put byteLength null bytes into this byte vector.
      byteOffset - index of the first byte of byteArrayValue that must be copied.
      byteLength - number of bytes of byteArrayValue that must be copied.
      Returns:
      this byte vector.
