//
// <synopsis>
// These functions allow the user to write either an entire or a
// partial <src>Block</src> out to an <src>ostream</src> or to
// <src>AipsIO</src>. These functions provide simple storage and
// display capabilities for <src>Block</src>.

//# It appears that (at least for the SUN compiler) the 3rd argument
//# cannot be an uInt (otherwise the compiler says no match when
//# called as e.g. putBlock(ios,blk,10);).
//#
//# Note that as of 29-Dec-2008 the size of Block is a size_t, so nr should
//# also be a size_t. However, because AipsIO cannot handle sizes larger than
//# an uInt, it makes no sense to make that change.
//
// These functions allow the user to read and write <src>Block</src>s
// from the <src>AipsIO</src> stream.
//
// <src>putBlock</src> writes the <src>Block</src> to the stream. If
// a number, <src>nr</src>, of elements is specified, only the first
// <src>nr</src> elements will be written out to <src>AipsI0</src>.
//
// <src>getBlock</src> reads a <src>Block</src> in from an
// <src>AipsIO</src> stream.
//

template<class T> void getBlock (AipsIO&, Block<T>&);

// These functions allow the user to write <src>Block</src>s out to
// a standard <src>ostream</src>. The user can either write the entire
// <src>Block</src> out to the stream, or if a number of elements,
// <src>nr</src>, is specified, only the first <src>nr</src> elements
// of the <src>Block</src> will be written out.

// These are the standard shift operators for writing an entire
// <src>Block</src> out to a stream. Shift operators are provided
// to write the block out to either <src>AipsIO</src> or
// <src>ostream</src>. A shift operator is also provided for
// reading a <src>Block</src> in from <src>AipsIO</src>.
// <note> STL containers like vector and list are written in the same way as
// a Block, so they can be written one way and read back the other.
// </note>
