                                              AbstractInstantiationError

Attempt to create an instance of an abstract complex type.

These types are analogous to abstract base classes, and cannot be created directly. A type should be used that extends the abstract class.

When an incoming document is missing the xsi:type attribute which redirects an element with an abstract type to the correct type, the node attribute is provided so the user can get a clue as to where the problem occured. When this exception is a result of constructor mis-use in Python code, the traceback will tell you where the problem lies.

Method Details | [hide private]

### __init__(self, type, location, node) (Constructor) | source code
Create an exception indicating a PyXB-related problem. If no args are present, a default argument is taken from the `message` keyword. Parameters: `type` - the value for the type attribute. `location` - the value for the location attribute. `node` - the value for the node attribute. Overrides: exceptions.BaseException.__init__

### __unicode__(self) | source code
Overrides: exceptions.BaseException.__unicode__

### __str__(self) (Informal representation operator) | source code
str(x) Overrides: exceptions.BaseException.__str__ (inherited documentation)
