The following attributes are only supported on the common to all reloading "batch-oriented" metadata providers (ResourceBackedMetadataProvideri.e., FileBackedHTTPMetadataProvider, FilesystemMetadataProvider, and FileBackedHTTPMetadataProviderResourceBackedMetadataProvider):
| Name | Type | Default | Description |
|---|---|---|---|
| parserPoolRef | Bean ID | shibboleth.ParserPool | Identifies a Spring bean for the (OpenSAML) ParserPool object used to parse incoming metadata. Generally should not be changed. |
| taskTimerRef | Bean ID | Identifies a Spring bean containing a Java TaskTimer used to schedule reloads. When not set, an internal timer is created. Generally should not be changed. | |
| minRefreshDelay | Duration | PT30S | Lower bound on the next refresh from the time calculated based on the metadata's expiration. |
| maxRefreshDelay | Duration | PT4H | Upper bound on the next refresh from the time calculated based on the metadata's expiration. |
| refreshDelayFactor | Real Number (strictly between 0.0 and 1.0) | 0.75 | A factor applied to the initially determined refresh time in order to determine the next refresh time (typically to ensure refresh takes place prior to the metadata's expiration). Attempts to refresh metadata will generally begin around the product of this number and the maximum refresh delay. |
| indexesRef 3.3 | Bean ID | Identifies an optional | |
| resolveViaPredicatesOnly 3.3 | Boolean | false | Flag indicating whether resolution may be performed solely by applying predicates to the entire metadata collection, when an entityID input criterion is not supplied. |
| expirationWarningThreshold 3.4 | Duration | PT0S (disabled) | For each attempted metadata refresh (whether or not fresh metadata is obtained), if requireValidMetadata is true, and there is a validUntil XML attribute on the document root element, and the difference between validUntil and the current time is less than expirationWarningThreshold, the system logs a warning about the impending expiration. |
