Method Detail





getCustomErrorResponsePolicy
public CustomErrorResponsePolicy getCustomErrorResponsePolicy()
customErrorResponsePolicy specifies how the Load Balancer returns error responses when
 BackendServiceor BackendBucket responds with an error. If a policy for an error code is not
 configured for the RouteRule, a policy for the error code configured in
 pathMatcher.defaultCustomErrorResponsePolicy is applied. If one is not specified in
 pathMatcher.defaultCustomErrorResponsePolicy, the policy configured in
 UrlMap.defaultCustomErrorResponsePolicy takes effect. For example, consider a UrlMap with the
 following configuration: - UrlMap.defaultCustomErrorResponsePolicy are configured with policies
 for 5xx and 4xx errors - A RouteRule for /coming_soon/ is configured for the error code 404. If
 the request is for www.myotherdomain.com and a 404 is encountered, the policy under
 UrlMap.defaultCustomErrorResponsePolicy takes effect. If a 404 response is encountered for the
 request www.example.com/current_events/, the pathMatcher's policy takes effect. If however, the
 request for www.example.com/coming_soon/ encounters a 404, the policy in
 RouteRule.customErrorResponsePolicy takes effect. If any of the requests in this example
 encounter a 500 error code, the policy at UrlMap.defaultCustomErrorResponsePolicy takes effect.
 When used in conjunction with routeRules.routeAction.retryPolicy, retries take precedence. Only
 once all retries are exhausted, the customErrorResponsePolicy is applied. While attempting a
 retry, if load balancer is successful in reaching the service, the customErrorResponsePolicy is
 ignored and the response from the service is returned to the client. customErrorResponsePolicy
 is supported only for global external Application Load Balancers.

Returns:
value or null for none








setCustomErrorResponsePolicy
public HttpRouteRule setCustomErrorResponsePolicy(CustomErrorResponsePolicy customErrorResponsePolicy)
customErrorResponsePolicy specifies how the Load Balancer returns error responses when
 BackendServiceor BackendBucket responds with an error. If a policy for an error code is not
 configured for the RouteRule, a policy for the error code configured in
 pathMatcher.defaultCustomErrorResponsePolicy is applied. If one is not specified in
 pathMatcher.defaultCustomErrorResponsePolicy, the policy configured in
 UrlMap.defaultCustomErrorResponsePolicy takes effect. For example, consider a UrlMap with the
 following configuration: - UrlMap.defaultCustomErrorResponsePolicy are configured with policies
 for 5xx and 4xx errors - A RouteRule for /coming_soon/ is configured for the error code 404. If
 the request is for www.myotherdomain.com and a 404 is encountered, the policy under
 UrlMap.defaultCustomErrorResponsePolicy takes effect. If a 404 response is encountered for the
 request www.example.com/current_events/, the pathMatcher's policy takes effect. If however, the
 request for www.example.com/coming_soon/ encounters a 404, the policy in
 RouteRule.customErrorResponsePolicy takes effect. If any of the requests in this example
 encounter a 500 error code, the policy at UrlMap.defaultCustomErrorResponsePolicy takes effect.
 When used in conjunction with routeRules.routeAction.retryPolicy, retries take precedence. Only
 once all retries are exhausted, the customErrorResponsePolicy is applied. While attempting a
 retry, if load balancer is successful in reaching the service, the customErrorResponsePolicy is
 ignored and the response from the service is returned to the client. customErrorResponsePolicy
 is supported only for global external Application Load Balancers.

Parameters:
customErrorResponsePolicy - customErrorResponsePolicy or null for none








getDescription
public String getDescription()
The short description conveying the intent of this routeRule. The description can have a
 maximum length of 1024 characters.

Returns:
value or null for none








setDescription
public HttpRouteRule setDescription(String description)
The short description conveying the intent of this routeRule. The description can have a
 maximum length of 1024 characters.

Parameters:
description - description or null for none








getHeaderAction
public HttpHeaderAction getHeaderAction()
Specifies changes to request and response headers that need to take effect for the selected
 backendService. The headerAction value specified here is applied before the matching
 pathMatchers[].headerAction and after pathMatchers[].routeRules[].routeAction.weightedBackendSe
 rvice.backendServiceWeightAction[].headerAction HeaderAction is not supported for load
 balancers that have their loadBalancingScheme set to EXTERNAL. Not supported when the URL map
 is bound to a target gRPC proxy that has validateForProxyless field set to true.

Returns:
value or null for none








setHeaderAction
public HttpRouteRule setHeaderAction(HttpHeaderAction headerAction)
Specifies changes to request and response headers that need to take effect for the selected
 backendService. The headerAction value specified here is applied before the matching
 pathMatchers[].headerAction and after pathMatchers[].routeRules[].routeAction.weightedBackendSe
 rvice.backendServiceWeightAction[].headerAction HeaderAction is not supported for load
 balancers that have their loadBalancingScheme set to EXTERNAL. Not supported when the URL map
 is bound to a target gRPC proxy that has validateForProxyless field set to true.

Parameters:
headerAction - headerAction or null for none








getMatchRules
public List<HttpRouteRuleMatch> getMatchRules()
The list of criteria for matching attributes of a request to this routeRule. This list has OR
 semantics: the request matches this routeRule when any of the matchRules are satisfied. However
 predicates within a given matchRule have AND semantics. All predicates within a matchRule must
 match for the request to match the rule.

Returns:
value or null for none








setMatchRules
public HttpRouteRule setMatchRules(List<HttpRouteRuleMatch> matchRules)
The list of criteria for matching attributes of a request to this routeRule. This list has OR
 semantics: the request matches this routeRule when any of the matchRules are satisfied. However
 predicates within a given matchRule have AND semantics. All predicates within a matchRule must
 match for the request to match the rule.

Parameters:
matchRules - matchRules or null for none








getPriority
public Integer getPriority()
For routeRules within a given pathMatcher, priority determines the order in which a load
 balancer interprets routeRules. RouteRules are evaluated in order of priority, from the lowest
 to highest number. The priority of a rule decreases as its number increases (1, 2, 3, N+1). The
 first rule that matches the request is applied. You cannot configure two or more routeRules
 with the same priority. Priority for each rule must be set to a number from 0 to 2147483647
 inclusive. Priority numbers can have gaps, which enable you to add or remove rules in the
 future without affecting the rest of the rules. For example, 1, 2, 3, 4, 5, 9, 12, 16 is a
 valid series of priority numbers to which you could add rules numbered from 6 to 8, 10 to 11,
 and 13 to 15 in the future without any impact on existing rules.

Returns:
value or null for none








setPriority
public HttpRouteRule setPriority(Integer priority)
For routeRules within a given pathMatcher, priority determines the order in which a load
 balancer interprets routeRules. RouteRules are evaluated in order of priority, from the lowest
 to highest number. The priority of a rule decreases as its number increases (1, 2, 3, N+1). The
 first rule that matches the request is applied. You cannot configure two or more routeRules
 with the same priority. Priority for each rule must be set to a number from 0 to 2147483647
 inclusive. Priority numbers can have gaps, which enable you to add or remove rules in the
 future without affecting the rest of the rules. For example, 1, 2, 3, 4, 5, 9, 12, 16 is a
 valid series of priority numbers to which you could add rules numbered from 6 to 8, 10 to 11,
 and 13 to 15 in the future without any impact on existing rules.

Parameters:
priority - priority or null for none








getRouteAction
public HttpRouteAction getRouteAction()
In response to a matching matchRule, the load balancer performs advanced routing actions, such
 as URL rewrites and header transformations, before forwarding the request to the selected
 backend. Only one of urlRedirect, service or routeAction.weightedBackendService can be set. URL
 maps for classic Application Load Balancers only support the urlRewrite action within a route
 rule's routeAction.

Returns:
value or null for none
