Class LambdaFunctionAssociations

java.lang.Object
software.amazon.awssdk.services.cloudfront.model.LambdaFunctionAssociations
All Implemented Interfaces:
Serializable, SdkPojo, ToCopyableBuilder<LambdaFunctionAssociations.Builder,LambdaFunctionAssociations>
@Generated("software.amazon.awssdk:codegen") public final class LambdaFunctionAssociations extends Object implements SdkPojo, Serializable, ToCopyableBuilder<LambdaFunctionAssociations.Builder,LambdaFunctionAssociations>

A complex type that specifies a list of Lambda@Edge functions associations for a cache behavior.

If you want to invoke one or more Lambda@Edge functions triggered by requests that match the PathPattern of the cache behavior, specify the applicable values for Quantity and Items. Note that there can be up to 4 LambdaFunctionAssociation items in this list (one for each possible value of EventType) and each EventType can be associated with only one function.

If you don't want to invoke any Lambda@Edge functions for the requests that match PathPattern, specify 0 for Quantity and omit Items.

  • Method Details

    • quantity

      public final Integer quantity()

      The number of Lambda@Edge function associations for this cache behavior.

      Returns:
      The number of Lambda@Edge function associations for this cache behavior.

    • hasItems

      public final boolean hasItems()
      For responses, this returns true if the service returned a value for the Items 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.

    • items

      public final List<LambdaFunctionAssociation> items()

      Optional: A complex type that contains LambdaFunctionAssociation items for this cache behavior. If Quantity is 0, you can omit Items.

      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 hasItems() method.

      Returns:
      Optional: A complex type that contains LambdaFunctionAssociation items for this cache behavior. If Quantity is 0, you can omit Items.

    • toBuilder

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

    • builder

      public static LambdaFunctionAssociations.Builder builder()

    • serializableBuilderClass

      public static Class<? extends LambdaFunctionAssociations.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.
