Class CachePolicy

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

A cache policy.

When it's attached to a cache behavior, the cache policy determines the following:

  • The values that CloudFront includes in the cache key. These values can include HTTP headers, cookies, and URL query strings. CloudFront uses the cache key to find an object in its cache that it can return to the viewer.

  • The default, minimum, and maximum time to live (TTL) values that you want objects to stay in the CloudFront cache.

The headers, cookies, and query strings that are included in the cache key are also included in requests that CloudFront sends to the origin. CloudFront sends a request when it can't find a valid object in its cache that matches the request's cache key. If you want to send values to the origin but not include them in the cache key, use OriginRequestPolicy.

      public final Instant lastModifiedTime()

      The date and time when the cache policy was last modified.

      Returns:
      The date and time when the cache policy was last modified.

      The cache policy configuration.

      Returns:
      The cache policy configuration.

    • toBuilder

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

    • builder

      public static CachePolicy.Builder builder()

    • serializableBuilderClass

      public static Class<? extends CachePolicy.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.
