public class UnsafeByteArrayOutputStream
extends ByteArrayOutputStream

An unsynchronized implementation of ByteArrayOutputStream that will return the backing byte array if its length == size(). This avoids unneeded array copy where the BOS is simply being used to extract a byte array of known length from a 'serialized to stream' method. Unless the final length can be accurately predicted the only performance this will yield is due to unsynchronized methods.

方法详细资料

write

public void write(int b)

Writes the specified byte to this byte array output stream.

覆盖:

write 在类中 ByteArrayOutputStream

参数:

b - the byte to be written.

write

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

Writes len bytes from the specified byte array starting at offset off to this byte array output stream.

覆盖:

write 在类中 ByteArrayOutputStream

参数:

b - the entity.

off - the start offset in the entity.

len - the number of bytes to write.

writeTo

public void writeTo(OutputStream out)
             throws IOException

Writes the complete contents of this byte array output stream to the specified output stream argument, as if by calling the output stream's write method using out.write(buf, 0, count).

覆盖:

writeTo 在类中 ByteArrayOutputStream

参数:

out - the output stream to which to write the entity.

抛出:

IOException - if an I/O error occurs.

reset

public void reset()

Resets the count field of this byte array output stream to zero, so that all currently accumulated output in the output stream is discarded. The output stream can be used again, reusing the already allocated buffer space.

覆盖:

reset 在类中 ByteArrayOutputStream

ByteArrayInputStream.count

toByteArray

public byte[] toByteArray()

Creates a newly allocated byte array. Its size is the current size of this output stream and the valid contents of the buffer have been copied into it.

覆盖:

toByteArray 在类中 ByteArrayOutputStream

返回:

the current contents of this output stream, as a byte array.

另请参阅:

ByteArrayOutputStream.size()

size

public int size()

Returns the current size of the buffer.

覆盖:

size 在类中 ByteArrayOutputStream

返回:

the value of the count field, which is the number of valid bytes in this output stream.

ByteArrayOutputStream.count
