void TBtLeafNode::Add	(	const TObject *	obj,

Add the object OBJ to the leaf node, inserting it at location INDEX in the fItem array.

Implements TBtNode.

void TBtLeafNode::Append ( TObject * obj )

Never called from anywhere where it might fill up THIS does NOT handle nofKeys.

void TBtLeafNode::AppendFrom	(	TBtLeafNode *	src,
		Int_t	start,
		Int_t	stop
	)

A convenience function, does not worry about the element in the parent, simply moves elements from SRC[start] to SRC[stop] into the current array.

This should never create a full node. That is, it is not used anywhere where THIS could possibly be near full. Does NOT handle nofKeys.
