Method Detail

defaultTTL

public Long defaultTTL()

The default amount of time that objects stay in the distribution's cache before the distribution forwards another request to the origin to determine whether the content has been updated.

The value specified applies only when the origin does not add HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects.

Returns:

The default amount of time that objects stay in the distribution's cache before the distribution forwards another request to the origin to determine whether the content has been updated.

The value specified applies only when the origin does not add HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects.

minimumTTL

public Long minimumTTL()

The minimum amount of time that objects stay in the distribution's cache before the distribution forwards another request to the origin to determine whether the object has been updated.

A value of 0 must be specified for minimumTTL if the distribution is configured to forward all headers to the origin.

Returns:

The minimum amount of time that objects stay in the distribution's cache before the distribution forwards another request to the origin to determine whether the object has been updated.

A value of 0 must be specified for minimumTTL if the distribution is configured to forward all headers to the origin.

maximumTTL

public Long maximumTTL()

The maximum amount of time that objects stay in the distribution's cache before the distribution forwards another request to the origin to determine whether the object has been updated.

The value specified applies only when the origin adds HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects.

Returns:

The maximum amount of time that objects stay in the distribution's cache before the distribution forwards another request to the origin to determine whether the object has been updated.

The value specified applies only when the origin adds HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects.

allowedHTTPMethods

public String allowedHTTPMethods()

The HTTP methods that are processed and forwarded to the distribution's origin.

You can specify the following options:

• GET,HEAD - The distribution forwards the GET and HEAD methods.

• GET,HEAD,OPTIONS - The distribution forwards the GET, HEAD, and OPTIONS methods.

• GET,HEAD,OPTIONS,PUT,PATCH,POST,DELETE - The distribution forwards the GET, HEAD, OPTIONS, PUT, PATCH, POST, and DELETE methods.

If you specify the third option, you might need to restrict access to your distribution's origin so users can't perform operations that you don't want them to. For example, you might not want users to have permission to delete objects from your origin.

Returns:

The HTTP methods that are processed and forwarded to the distribution's origin.

You can specify the following options:

• GET,HEAD - The distribution forwards the GET and HEAD methods.

• GET,HEAD,OPTIONS - The distribution forwards the GET, HEAD, and OPTIONS methods.

• GET,HEAD,OPTIONS,PUT,PATCH,POST,DELETE - The distribution forwards the GET, HEAD, OPTIONS, PUT, PATCH, POST, and DELETE methods.

If you specify the third option, you might need to restrict access to your distribution's origin so users can't perform operations that you don't want them to. For example, you might not want users to have permission to delete objects from your origin.

cachedHTTPMethods

public String cachedHTTPMethods()

The HTTP method responses that are cached by your distribution.

You can specify the following options:

• GET,HEAD - The distribution caches responses to the GET and HEAD methods.

• GET,HEAD,OPTIONS - The distribution caches responses to the GET, HEAD, and OPTIONS methods.

Returns:

The HTTP method responses that are cached by your distribution.

You can specify the following options:

• GET,HEAD - The distribution caches responses to the GET and HEAD methods.

• GET,HEAD,OPTIONS - The distribution caches responses to the GET, HEAD, and OPTIONS methods.

forwardedCookies

public CookieObject forwardedCookies()

An object that describes the cookies that are forwarded to the origin. Your content is cached based on the cookies that are forwarded.

Returns:

An object that describes the cookies that are forwarded to the origin. Your content is cached based on the cookies that are forwarded.

forwardedHeaders

public HeaderObject forwardedHeaders()

An object that describes the headers that are forwarded to the origin. Your content is cached based on the headers that are forwarded.

Returns:

An object that describes the headers that are forwarded to the origin. Your content is cached based on the headers that are forwarded.

forwardedQueryStrings

public QueryStringObject forwardedQueryStrings()

An object that describes the query strings that are forwarded to the origin. Your content is cached based on the query strings that are forwarded.

Returns:

An object that describes the query strings that are forwarded to the origin. Your content is cached based on the query strings that are forwarded.

toBuilder

public CacheSettings.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<CacheSettings.Builder,CacheSettings>

Returns:

a builder for type T

builder

public static CacheSettings.Builder builder()

serializableBuilderClass

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

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

equalsBySdkFields

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

sdkFields

public 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.
