FieldCollection class
FieldCollection class
A collection of Field objects that represents the fields in the specified range. To learn more, visit the Working with Fields documentation article.
Remarks
An instance of this collection iterates fields which start fall within the specified range.
The FieldCollection collection does not own the fields it contains, rather, is just a selection of fields.
The FieldCollection collection is “live”, i.e. changes to the children of the node object that it was created from are immediately reflected in the fields returned by the FieldCollection properties and methods.

Examples
Shows how to remove fields from a field collection.
doc = aw.Document()
builder = aw.DocumentBuilder(doc=doc)
builder.insert_field(field_code=' DATE \\@ "dddd, d MMMM yyyy" ')
builder.insert_field(field_code=' TIME ')
builder.insert_field(field_code=' REVNUM ')
builder.insert_field(field_code=' AUTHOR "John Doe" ')
builder.insert_field(field_code=' SUBJECT "My Subject" ')
builder.insert_field(field_code=' QUOTE "Hello world!" ')
doc.update_fields()
fields = doc.range.fields
self.assertEqual(6, fields.count)
# Below are four ways of removing fields from a field collection.
# 1 - Get a field to remove itself:
fields[0].remove()
self.assertEqual(5, fields.count)
# 2 - Get the collection to remove a field that we pass to its removal method:
last_field = fields[3]
fields.remove(last_field)
self.assertEqual(4, fields.count)
# 3 - Remove a field from a collection at an index:
fields.remove_at(2)
self.assertEqual(3, fields.count)
# 4 - Remove all the fields from the collection at once:
fields.clear()
self.assertEqual(0, fields.count)
