@Generated("software.amazon.awssdk:codegen") public final class ChangeEvent extends Object implements SdkPojo, Serializable, ToCopyableBuilder<ChangeEvent.Builder,ChangeEvent>

Represents a change event that occurred in the system, such as deployments, configuration changes, or other operational events that may impact service performance.

  • Method Details

    • timestamp

      public final Instant timestamp()

      The timestamp when the change event occurred, expressed as the number of milliseconds since January 1, 1970, 00:00:00 UTC.

      Returns:
      The timestamp when the change event occurred, expressed as the number of milliseconds since January 1, 1970, 00:00:00 UTC.

    • accountId

      public final String accountId()

      The AWS account ID where the change event occurred.

      Returns:
      The AWS account ID where the change event occurred.

    • region

      public final String region()

      The AWS region where the change event occurred.

      Returns:
      The AWS region where the change event occurred.

    • hasEntity

      public final boolean hasEntity()
      For responses, this returns true if the service returned a value for the Entity property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • entity

      public final Map<String,String> entity()

      The entity or resource that was changed, such as a service, deployment, or configuration.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasEntity() method.

      Returns:
      The entity or resource that was changed, such as a service, deployment, or configuration.

    • changeEventType

      public final ChangeEventType changeEventType()

      The type of change that occurred, such as "Deployment", "Configuration", or "Infrastructure".

      If the service returns an enum value that is not available in the current SDK version, changeEventType will return ChangeEventType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from changeEventTypeAsString().

      Returns:
      The type of change that occurred, such as "Deployment", "Configuration", or "Infrastructure".
      See Also:

    • changeEventTypeAsString

      public final String changeEventTypeAsString()

      The type of change that occurred, such as "Deployment", "Configuration", or "Infrastructure".

      If the service returns an enum value that is not available in the current SDK version, changeEventType will return ChangeEventType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from changeEventTypeAsString().

      Returns:
      The type of change that occurred, such as "Deployment", "Configuration", or "Infrastructure".
      See Also:

    • eventId

      public final String eventId()

      A unique identifier for the change event.

      Returns:
      A unique identifier for the change event.

    • userName

      public final String userName()

      The name of the user or system that initiated the change event.

      Returns:
      The name of the user or system that initiated the change event.

    • eventName

      public final String eventName()

      A descriptive name for the change event that provides context about what changed.

      Returns:
      A descriptive name for the change event that provides context about what changed.

    • toBuilder

      public ChangeEvent.Builder toBuilder()
      Description copied from interface: ToCopyableBuilder
      Take this object and create a builder that contains all of the current property values of this object.
      Specified by:
      toBuilder in interface ToCopyableBuilder<ChangeEvent.Builder,ChangeEvent>
      Returns:
      a builder for type T

    • builder

      public static ChangeEvent.Builder builder()

    • serializableBuilderClass

      public static Class<? extends ChangeEvent.Builder> serializableBuilderClass()

    • hashCode

      public final int hashCode()
      Overrides:
      hashCode in class Object

    • equals

      public final boolean equals(Object obj)
      Overrides:
      equals in class Object

    • equalsBySdkFields

      public final boolean equalsBySdkFields(Object obj)
      Description copied from interface: SdkPojo
      Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

      If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

      Specified by:
      equalsBySdkFields in interface SdkPojo
      Parameters:
      obj - the object to be compared with
      Returns:
      true if the other object equals to this object by sdk fields, false otherwise.

    • toString

      public final String toString()
      Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
      Overrides:
      toString in class Object

    • getValueForField

      public final <T> Optional<T> getValueForField(String fieldName, Class<T> clazz)

    • sdkFields

      public final List<SdkField<?>> sdkFields()
      Specified by:
      sdkFields in interface SdkPojo
      Returns:
      List of SdkField in this POJO. May be empty list but should never be null.

    • sdkFieldNameToField

      public final Map<String,SdkField<?>> sdkFieldNameToField()
      Specified by:
      sdkFieldNameToField in interface SdkPojo
      Returns:
      The mapping between the field name and its corresponding field.
