@InterfaceAudience.Private
public class ByteArrayOutputStream
extends OutputStream
implements ByteBufferWriter

write

public void write(ByteBuffer b,
                  int off,
                  int len)

从接口复制的说明: ByteBufferWriter

Writes len bytes from the specified ByteBuffer starting at offset off

指定者:

write 在接口中 ByteBufferWriter

参数:

b - the data.

off - the start offset in the data.

len - the number of bytes to write.

writeInt

public void writeInt(int i)

从接口复制的说明: ByteBufferWriter

Writes an int to the underlying output stream as four bytes, high byte first.

指定者:

writeInt 在接口中 ByteBufferWriter

参数:

i - the int to write

write

public void write(int b)

指定者:

write 在类中 OutputStream

write

public void write(byte[] b,
                  int off,
                  int len)

覆盖:

write 在类中 OutputStream

reset

public void reset()

Resets the pos field of this byte array output stream to zero. The output stream can be used again.

toByteArray

public byte[] toByteArray()

Copies the content of this Stream into a new byte array.

返回:

the contents of this output stream, as new byte array.

getBuffer

public byte[] getBuffer()

返回:

the underlying array where the data gets accumulated

size

public int size()

返回:

The current size of the buffer.
