Class ExecutionAttributes

java.lang.Object

software.amazon.awssdk.core.interceptor.ExecutionAttributes

All Implemented Interfaces:

ToCopyableBuilder<ExecutionAttributes.Builder,ExecutionAttributes>

@NotThreadSafe
public class ExecutionAttributes
extends Object
implements ToCopyableBuilder<ExecutionAttributes.Builder,ExecutionAttributes>

A mutable collection of ExecutionAttributes that can be modified by ExecutionInterceptors in order to save and retrieve information specific to the current execution. This is useful for sharing data between ExecutionInterceptor method calls specific to a particular execution.

Nested Class Summary

Nested Classes

Modifier and Type	Class	Description
static class	ExecutionAttributes.Builder	TODO: We should deprecate this builder - execution attributes are mutable - why do we need a builder? We can just use copy() if it's because of unmodifiableExecutionAttributes(ExecutionAttributes).
