com.alibaba.fastjson.asm Class ByteVector

java.lang.Object
  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.

Author:: Eric Bruneton

Constructor Summary
`ByteVector()` Constructs a new `ByteVector` with a default initial size.
`ByteVector(int initialSize)` Constructs a new `ByteVector` with the given initial size.

Method Summary
`ByteVector`	`putByte(int b)` Puts a byte into this byte vector.
`ByteVector`	`putByteArray(byte[] b, int off, int len)` Puts an array of bytes into this byte vector.
`ByteVector`	`putInt(int i)` Puts an int into this byte vector.
`ByteVector`	`putShort(int s)` Puts a short into this byte vector.
`ByteVector`	`putUTF8(String s)` Puts an UTF8 string into this byte vector.

Constructor Detail

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 Detail

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.

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.

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.

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.
