CustomScalarAdapters

class CustomScalarAdapters : ExecutionContext.Element

A wrapper around a MapAdapter> used to retrieve custom scalar adapters at runtime.

For historical reasons, it also contains other context used when parsing response. See https://github.com/apollographql/apollo-kotlin/pull/3813

Types

object Key : ExecutionContext.Key<CustomScalarAdapters>

Properties

deferredFragmentIdentifiers

val deferredFragmentIdentifiers: Set<DeferredFragmentIdentifier>?

Defer identifiers used to determine whether the parser must parse @defer fragments

val errors: List<Error>?

Errors to use with @catch

val falseVariables: Set<String>?

Operation variables used to determine whether the parser must parse @skip/@include fragments

open override val key: ExecutionContext.Key<*>

A key of this execution context element.

Functions

fun <T : Any> adapterFor(name: String): Adapter<T>?

firstErrorStartingWith

@ApolloExperimental

fun firstErrorStartingWith(path: List<Any>): Error?

open override fun <R> fold(initial: R, operation: (R, ExecutionContext.Element) -> R): R

Accumulates entries of this context starting with initial value and applying operation from left to right to current accumulator value and each element of this context.

open operator override fun <E : ExecutionContext.Element> get(key: ExecutionContext.Key<E>): E?

Returns the element with the given key from this context or null.

open override fun minusKey(key: ExecutionContext.Key<*>): ExecutionContext

Returns a context containing elements from this context, but without an element with the specified key.

fun newBuilder(): CustomScalarAdapters.Builder

open operator fun plus(context: ExecutionContext): ExecutionContext

Returns a context containing elements from this context and elements from other context. The elements from this context with the same key as in the other one are dropped.
