Modifier and Type	Method	Description
InstrumentationContext<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<List<ValidationError>>	beginValidation(InstrumentationValidationParameters parameters, InstrumentationState rawState)	This is called just before the parsed query document is validated.
@Nullable CompletableFuture<InstrumentationState>	createStateAsync(InstrumentationCreateStateParameters parameters)	This will be called just before execution to create an object, in an asynchronous manner, that is given back to all instrumentation methods to allow them to have per execution request state
@NonNull CompletableFuture<ExecutionResult>	instrumentExecutionResult(ExecutionResult executionResult, InstrumentationExecutionParameters parameters, InstrumentationState rawState)	This is called to allow instrumentation to instrument the execution result in some way

Method Details

createStateAsync

public @Nullable CompletableFuture<InstrumentationState> createStateAsync(InstrumentationCreateStateParameters parameters)

Description copied from interface: Instrumentation

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

Specified by:

createStateAsync in interface Instrumentation

Overrides:

createStateAsync in class SimplePerformantInstrumentation

Parameters:

parameters - the parameters to this step

Returns:

a state object that is passed to each method

instrumentExecutionResult

public @NonNull CompletableFuture<ExecutionResult> instrumentExecutionResult(ExecutionResult executionResult,
 InstrumentationExecutionParameters parameters,
 InstrumentationState rawState)

Description copied from interface: Instrumentation

This is called to allow instrumentation to instrument the execution result in some way

Specified by:

instrumentExecutionResult in interface Instrumentation

Overrides:

instrumentExecutionResult in class SimplePerformantInstrumentation

Parameters:

executionResult - CompletableFuture of the result to instrument

parameters - the parameters to this step

rawState - the state created during the call to Instrumentation.createStateAsync(InstrumentationCreateStateParameters)

Returns:

a new execution result completable future

beginFieldFetch

public InstrumentationContext<Object> beginFieldFetch(InstrumentationFieldFetchParameters parameters,
 InstrumentationState rawState)

Description copied from interface: Instrumentation

This is called just before a field DataFetcher is invoked.

Specified by:

beginFieldFetch in interface Instrumentation

Overrides:

beginFieldFetch in class SimplePerformantInstrumentation

Parameters:

parameters - the parameters to this step

rawState - the state created during the call to Instrumentation.createStateAsync(InstrumentationCreateStateParameters)

Returns:

a nullable InstrumentationContext object that will be called back when the step ends (assuming it's not null)

beginParse

public InstrumentationContext<Document> beginParse(InstrumentationExecutionParameters parameters,
 InstrumentationState rawState)

Description copied from interface: Instrumentation

This is called just before a query is parsed.

Specified by:

beginParse in interface Instrumentation

Overrides:

beginParse in class SimplePerformantInstrumentation

Parameters:

parameters - the parameters to this step

rawState - the state created during the call to Instrumentation.createStateAsync(InstrumentationCreateStateParameters)

Returns:

a nullable InstrumentationContext object that will be called back when the step ends (assuming it's not null)

beginValidation

public InstrumentationContext<List<ValidationError>> beginValidation(InstrumentationValidationParameters parameters,
 InstrumentationState rawState)

Description copied from interface: Instrumentation

This is called just before the parsed query document is validated.

Specified by:

beginValidation in interface Instrumentation

Overrides:

beginValidation in class SimplePerformantInstrumentation

Parameters:

parameters - the parameters to this step

rawState - the state created during the call to Instrumentation.createStateAsync(InstrumentationCreateStateParameters)

Returns:

a nullable InstrumentationContext object that will be called back when the step ends (assuming it's not null)
