public class MultiByteArrayOutputStream
extends OutputStream

This class implements an output stream in which the data is written into a byte array. The buffer automatically grows as data is written to it. The data can be retrieved using toByteArrays() and toString().

Closing a MultiByteArrayOutputStream has no effect. The methods in this class can be called after the stream has been closed without generating an IOException.

从以下版本开始:

0.3.4

Implementation Requirements:

This class is thread-safe.

构造器详细资料

MultiByteArrayOutputStream

public MultiByteArrayOutputStream()

Creates a new byte array output stream. The buffer capacity is initially 10240 bytes, though its size increases if necessary.

MultiByteArrayOutputStream

public MultiByteArrayOutputStream(int size)

Creates a new byte array output stream, with a buffer capacity of the specified size, in bytes.

参数:

size - the initial size.

抛出:

IllegalArgumentException - if size is negative.

方法详细资料

write

public void write(int b)

Writes the specified byte to this byte array output stream.

指定者:

write 在类中 OutputStream

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 OutputStream

参数:

b - the data.

off - the start offset in the data.

len - the number of bytes to write.

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.

count

toByteArrays

public byte[][] toByteArrays()

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.

返回:

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

另请参阅:

size()

size

public long size()

Returns the current size of the buffer.

返回:

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

count

close

public void close()
           throws IOException

Closing a MultiByteArrayOutputStream has no effect. The methods in this class can be called after the stream has been closed without generating an IOException.

指定者:

close 在接口中 AutoCloseable

指定者:

close 在接口中 Closeable

覆盖:

close 在类中 OutputStream

抛出:

IOException
