Features
- Converting Enums
- Converting Interfaces
- Converting Types to Classes
- Apply TypeExtension to Classes if Type(Class) with the defined name exists othervise creates new class
- Automatically implements Interface fields inside Class
- other coming soon
# WORK IN PROGRESS
## Current working example
At this point it converts this schema
```graphql
schema {
query: Query
mutation: Mutation
}
# The query type, represents all of the entry points into our object graph
type Query {
hero(episode: Episode): Character
reviews(episode: Episode!): [Review]
search(text: String): [SearchResult]
character(id: ID!): Character
droid(id: ID!): Droid
human(id: ID!): Human
starship(id: ID!): Starship
}
# The mutation type, represents all updates we can make to our data
type Mutation {
createReview(episode: Episode, review: ReviewInput!): Review
}
# The episodes in the Star Wars trilogy
enum Episode {
# Star Wars Episode IV: A New Hope, released in 1977.
NEWHOPE
# Star Wars Episode V: The Empire Strikes Back, released in 1980.
