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

Contains information about an event source for an Lambda function. The event source defines the topics on which this Lambda function subscribes to receive messages that run the function.

    • topic

      public final String topic()

      The topic to which to subscribe to receive event messages.

      Returns:
      The topic to which to subscribe to receive event messages.

    • type

      public final LambdaEventSourceType type()

      The type of event source. Choose from the following options:

      • PUB_SUB – Subscribe to local publish/subscribe messages. This event source type doesn't support MQTT wildcards (+ and #) in the event source topic.

      • IOT_CORE – Subscribe to Amazon Web Services IoT Core MQTT messages. This event source type supports MQTT wildcards (+ and #) in the event source topic.

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

      Returns:
      The type of event source. Choose from the following options:

    • toBuilder

      public LambdaEventSource.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<LambdaEventSource.Builder,LambdaEventSource>
      Returns:
      a builder for type T

    • builder

    • serializableBuilderClass

      public static Class<? extends LambdaEventSource.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.
