## About

**ObjectMapper** is a class for automatic object mapping inspired by .NET **AutoMapper**.
It helps you to create objects between project layers (data layer, service layer, view) in a simple, transparent way.

## Example

1. **Mapping of the properties without mapping definition**

In this case are mapped only these properties of the target class which
are in target and source classes. Other properties are not mapped.
Suppose we have class `A` with attributes `name` and `last_name`
and class `B` with attribute `name`.
Initialization of the ObjectMapper will be:

```python
mapper = ObjectMapper()
mapper.create_map(A, B)
instance_b = mapper.map(A(), B)
```

In this case, value of A.name will be copied into B.name.

2. **Mapping with defined mapping functions**

Suppose we have class `A` with attributes `first_name` and `last_name`
, class `B` with attribute `full_name` and class `C` with attribute reverse_name.
And want to map it in a way `B.full_name = A.first_name + A.last_name` and
`C.reverse_name = A.last_name + A.first_name`
Initialization of the ObjectMapper will be:

```python
mapper = ObjectMapper()
mapper.create_map(A, B, {'name': lambda a : a.first_name + " " + a.last_name})
mapper.create_map(A, C, {'name': lambda a : a.last_name + " " + a.first_name})

instance_b = mapper.map(A(), B)
instance_c = mapper.map(A(), C)
```

In this case, to the `B.name` will be mapped `A.first_name + " " + A.last_name`
In this case, to the `C.name` will be mapped `A.last_name + " " + A.first_name`

3. **Mapping suppression**

For some purposes, it can be needed to suppress some mapping.
Suppose we have class `A` with attributes `name` and `last_name`
and class `B` with attributes `name` and `last_name`.
And we want to map only the `A.name` into `B.name`, but not `A.last_name` to
`B.last_name`
Initialization of the ObjectMapper will be:

```python
mapper = ObjectMapper()
mapper.create_map(A, B, {'last_name': None})

instance_b = mapper.map(A(), B)
```

In this case, value of A.name will be copied into `B.name` automatically by the attribute name `name`.
Attribute `A.last_name` will be not mapped thanks the suppression (lambda function is None).

4. **Case insensitive mapping**

Suppose we have class `A` with attributes `Name` and `Age` and
class `B` with attributes `name` and `age` and we want to map `A` to `B` in a way
`B.name` = `A.Name` and `B.age` = `A.Age`
Initialization of the ObjectMapper will be:

```python
mapper = ObjectMapper()
mapper.create_map(A, B)
instance_b = mapper.map(A(), B, ignore_case=True)
```

In this case, the value of A.Name will be copied into B.name and
the value of A.Age will be copied into B.age.

**Note:** You can find more examples in tests package
