Examples of com.fasterxml.jackson.databind.type.TypeFactory

com.fasterxml.jackson.databind.type.TypeFactory
Class used for creating concrete {@link JavaType} instances,given various inputs.
Instances of this class are accessible using {@link com.fasterxml.jackson.databind.ObjectMapper}as well as many objects it constructs (like {@link com.fasterxml.jackson.databind.DeserializationConfig} and{@link com.fasterxml.jackson.databind.SerializationConfig})), but usually those objects also expose convenience methods (constructType). So, you can do for example:
```
 JavaType stringType = mapper.constructType(String.class); 
```
However, more advanced methods are only exposed by factory so that you may need to use:
```
 JavaType stringCollection = mapper.getTypeFactory().constructCollectionType(List.class, String.class); 
```

                mapper._deserializationContext = mapper._deserializationContext.with(df);
            }


//          @Override
            public void addTypeModifier(TypeModifier modifier) {
                TypeFactory f = mapper._typeFactory;
                f = f.withModifier(modifier);
                mapper.setTypeFactory(f);
            }


//          @Override
            public void addValueInstantiators(ValueInstantiators instantiators) {
