com.alibaba.fastjson.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.

构造器详细资料

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.

参数:

initialSize - the initial size of the byte vector to be constructed.

方法详细资料

putByte

public ByteVector putByte(int b)

Puts a byte into this byte vector. The byte vector is automatically enlarged if necessary.

参数:

b - a byte.

返回:

this byte vector.

putShort

public ByteVector putShort(int s)

Puts a short into this byte vector. The byte vector is automatically enlarged if necessary.

参数:

s - a short.

返回:

this byte vector.

putInt

public ByteVector putInt(int i)

Puts an int into this byte vector. The byte vector is automatically enlarged if necessary.

参数:

i - an int.

返回:

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.

参数:

s - a String.

返回:

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.

参数:

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.

返回:

this byte vector.
