Method Details

observesValues

public static LegacyCoercingInputInterceptor observesValues(BiConsumer<Object, GraphQLInputType> observerCallback)

This will ONLY observe legacy values and invoke the callback when it gets one. you can use this to enumerate how many legacy values are hitting you graphql implementation

Parameters:

observerCallback - a callback allowing you to observe a legacy scalar value

Returns:

an InputInterceptor that only observes values

migratesValues

public static LegacyCoercingInputInterceptor migratesValues()

This will change legacy values as it encounters them to something acceptable to the more strict coercion rules.

Returns:

an InputInterceptor that migrates values to a more strict value

migratesValues

public static LegacyCoercingInputInterceptor migratesValues(BiConsumer<Object, GraphQLInputType> observerCallback)

This will change legacy values as it encounters them to something acceptable to the more strict coercion rules. The observer callback will be invoked if it detects a legacy value that it will change.

Parameters:

observerCallback - a callback allowing you to observe a legacy scalar value before it is migrated

Returns:

an InputInterceptor that both observes values and migrates them to a more strict value

intercept

public Object intercept(@Nullable
 @Nullable Object input,
 @NotNull
 @NotNull GraphQLInputType graphQLType,
 @NotNull
 @NotNull GraphQLContext graphqlContext,
 @NotNull
 @NotNull Locale locale)

Description copied from interface: InputInterceptor

This is called with a value that is to be presented to the ValuesResolver code. The values may be scalars, enums and complex input types.

Specified by:

intercept in interface InputInterceptor

Parameters:

input - the input value that can be null

graphQLType - the input type

graphqlContext - the graphql context in play

locale - the locale in play

Returns:

a value that may differ from the original value
