Class ByteVector

java.lang.Object

scala.tools.asm.ByteVector

public class ByteVector
extends java.lang.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 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 Detail

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(java.lang.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.
