Member Function Documentation

add()

def psyclone.f2pygen.IfThenGen.add	(		self,
			new_object,
			position = None
	)

Adds a new object to the tree. The actual position is determined by
the position argument. Note, there are two trees, the first is
the f2pygen object tree, the other is the f2py generated code
tree. These are similar but different. At the moment we
specify where to add things in terms of the f2pygen tree
(which is a higher level api) but we also insert into the f2py
tree at exactly the same location which needs to be sorted out
at some point.
