XInputStream
Hello,
The methods readBytes and readSomeBytes have an argument Byte[][] .
But shouldn't it be Byte[] ? because java.io.InputStream reads to a byte[]?
What is the point of having a byte [][]?
This example also suggests this:
http://forum.openoffice.org/en/forum/viewtopic.php?t=3801
They copy the ans to buffer[0] in buffer[][].

the IDL definition says it is an "out" parameter and "out" parameters
are mapped in Java to arrays of length 1. The caller of this method is
responsible for this parameter.
In C++ it's a reference parameter that is already created/initialized
and that can be changed or better filled in the method.

Hello,
Also in the file XInputStream implementation,
readSomeBytes() implementation just calls readBytes() method.
Code:
sal_Int32 SAL_CALL
XInputStream_impl::readSomeBytes(
uno::Sequence< sal_Int8 >& aData,
sal_Int32 nMaxBytesToRead )
throw( io::NotConnectedException,
io::BufferSizeExceededException,
io::IOException,
uno::RuntimeException)
{
return readBytes( aData,nMaxBytesToRead );
}
But this behaviour is not like the one described in
http://www.openoffice.org/api/docs/common/ref/com/sun/star/io/XInputStream.html#readBytes
.
Should I also do the same?
