Modifier and Type	Method and Description
InstrumentationContext<java.lang.Object>	beginFieldFetch(InstrumentationFieldFetchParameters parameters) This is called just before a field DataFetcher is invoked.
InstrumentationContext<Document>	beginParse(InstrumentationExecutionParameters parameters) This is called just before a query is parsed.
InstrumentationContext<java.util.List<ValidationError>>	beginValidation(InstrumentationValidationParameters parameters) This is called just before the parsed query document is validated.
InstrumentationState	createState() This will be called just before execution to create an object that is given back to all instrumentation methods to allow them to have per execution request state
java.util.concurrent.CompletableFuture<ExecutionResult>	instrumentExecutionResult(ExecutionResult executionResult, InstrumentationExecutionParameters parameters) This is called to allow instrumentation to instrument the execution result in some way

Description copied from interface: Instrumentation

This will be called just before execution to create an object that is given back to all instrumentation methods to allow them to have per execution request state

Returns:

a state object that is passed to each method

instrumentExecutionResult
