Constructor Details

NoCopyByteArrayOutputStream

public NoCopyByteArrayOutputStream()

Create a new output stream with default initial capacity.

NoCopyByteArrayOutputStream

public NoCopyByteArrayOutputStream(int size)

Create a new output stream with the specified initial capacity.

Parameters:

size - the initial capacity of the internal buffer

Method Details

array

public byte[] array()

Get the underlying buffer. Data was added to this buffer up to size(). Note that calling this method again may return a different result if additional data was inserted and the buffer had to grow.

asInputStream

public ByteArrayInputStream asInputStream()

Get an InputStream view on this object, based on the current buffer and size.

asByteBuffer

public ByteBuffer asByteBuffer()

Get a ByteBuffer view on this object, based on the current buffer and size.
