Transform (Speedment - Common - CodeGen 3.2.10 API)

Type Parameters:

F - the model to generate from

T - the resulting model

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface Transform<F,T>
```
Transforms must have a public constructor with no parameters so that it can be instantiated dynamically.

Since:

2.0

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`default boolean`	`is(Class<? extends Transform<?,?>> transformer)`	Returns true if this transform is or contains the specified transformer.
`Optional<T>`	`transform(Generator gen, F model)`	Transforms a model from one type to another.

  - transform
```
Optional<T> transform(Generator gen,
                      F model)
```
    Transforms a model from one type to another. A reference to the current code generator is supplied so that intermediate generation processes can be initiated to resolve dependencies. The transform can choose not to accept a particular input and therefore return empty.
    This method is not meant to be called outside the code generator. If you want to transform between different types, setup a Generator, install the Transform in the factory and call one of the on()-methods in Generator.
    
    Parameters:
    
    gen - a reference to the generator being used
    
    model - the model to transform
    
    Returns:
    
    the transformed model or empty if the transformation could not be done for that input
  - is
```
default boolean is(Class<? extends Transform<?,?>> transformer)
```
    Returns true if this transform is or contains the specified transformer. This is used internally by the code generator to avoid circular paths.
    
    Parameters:
    
    transformer - the type of the transformer to check
    
    Returns:
    
    true if this transform is or contains the input
