public class ByteArrayListOutputStream
extends ReversibleOutputStream

An OutputStream that writes to a list of byte arrays. The buffers have a minimum size. If a write operation is smaller than the minimum size, the data is stored in a separate buffer. This buffer will be filled up by subsequent writings to the minimum size before another buffer is created.

Constructor Details

ByteArrayListOutputStream

public ByteArrayListOutputStream()

Creates a new ByteArrayListOutputStream with a minimum buffer size of 4096 bytes.

ByteArrayListOutputStream

public ByteArrayListOutputStream(int minBufferSize)

Creates a new ByteArrayListOutputStream with the given minimum buffer size.

Parameters:

minBufferSize - the minimum buffer size

Method Details

write

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

Overrides:

write in class OutputStream

Throws:

IOException

write

public void write(int b)
           throws IOException

Specified by:

write in class OutputStream

Throws:

IOException

size

public long size()

Specified by:

size in class ReversibleOutputStream

getBuffers

public List<byte[]> getBuffers()

Returns the list of buffers. The list does not contain the current buffer. If the stream is closed, the current buffer is trimmed to the actual size and then added to the list.

Returns:

the list of buffers

close

public void close()
           throws IOException

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Overrides:

close in class OutputStream

Throws:

IOException

toInputStream

public InputStream toInputStream()

Specified by:

toInputStream in class ReversibleOutputStream
