PoolingByteArrayOutputStream

public PoolingByteArrayOutputStream(ByteArrayPool pool)

Constructs a new PoolingByteArrayOutputStream with a default size. If more bytes are written to this instance, the underlying byte array will expand.

PoolingByteArrayOutputStream

public PoolingByteArrayOutputStream(ByteArrayPool pool,
                                    int size)

Constructs a new ByteArrayOutputStream with a default size of size bytes. If more than size bytes are written to this instance, the underlying byte array will expand.

参数:

size - initial size for the underlying byte array. The value will be pinned to a default minimum size.
