Class ChainedInstrumentation

java.lang.Object

graphql.execution.instrumentation.ChainedInstrumentation

All Implemented Interfaces:

Instrumentation

Direct Known Subclasses:

NoContextChainedInstrumentation

@PublicApi
public class ChainedInstrumentation
extends java.lang.Object
implements Instrumentation

This allows you to chain together a number of Instrumentation implementations and run them in sequence. The list order of instrumentation objects is always guaranteed to be followed and the InstrumentationState objects they create will be passed back to the originating implementation.
