Class PrettyAstPrinter

java.lang.Object

graphql.language.AstPrinter

graphql.language.PrettyAstPrinter

@ExperimentalApi
public class PrettyAstPrinter
extends AstPrinter

A printer that acts as a code formatter. This printer will preserve pretty much all elements from the source text, even those that are not part of the AST (and are thus discarded by the AstPrinter), like comments.
