Modifier and Type	Method	Description
InstrumentationContext<java.lang.Object>	beginFieldFetch(InstrumentationFieldFetchParameters parameters, InstrumentationState rawState)	This is called just before a field DataFetcher is invoked.
InstrumentationContext<Document>	beginParse(InstrumentationExecutionParameters parameters, InstrumentationState rawState)	This is called just before a query is parsed.
InstrumentationContext<java.util.List<ValidationError>>	beginValidation(InstrumentationValidationParameters parameters, InstrumentationState rawState)	This is called just before the parsed query document is validated.
@Nullable InstrumentationState	createState(InstrumentationCreateStateParameters parameters)	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
@NotNull java.util.concurrent.CompletableFuture<ExecutionResult>	instrumentExecutionResult(ExecutionResult executionResult, InstrumentationExecutionParameters parameters, InstrumentationState rawState)	This is called to allow instrumentation to instrument the execution result in some way

Method Detail

createState

@Nullable
public @Nullable InstrumentationState createState(InstrumentationCreateStateParameters parameters)

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

Specified by:

createState in interface Instrumentation

Overrides:

createState in class SimplePerformantInstrumentation

Parameters:

parameters - the parameters to this step

Returns:

a state object that is passed to each method

instrumentExecutionResult

@NotNull
