cf.ConstructList

---

class cf.ConstructList(constructs=None)

An ordered sequence of constructs.

The elements of the list are construct of the same type.

The list supports the python list-like operations (such as indexing and methods like append).

>>> fl = cf.ConstructList()
>>> len(fl)
0
>>> fl = cf.FieldList(f)
>>> len(fl)
1
>>> fl = cf.FieldList([f, g])
>>> len(fl)
2
>>> fl = cf.FieldList(cf.FieldList([f] * 3))
>>> len(fl)
3
>>> len(fl + fl)
6

Such methods provide functionality similar to that of a built-in list. The main difference is that when an element needs to be assessed for equality its equals method is used, rather than the == operator.

Initialisation

Parameters:

constructs: (sequence of) constructs

Create a new list with these constructs.
