MetadataProviderReloadingAttributes

The following attributes are common to all reloading "batch-oriented" metadata providers (i.e., FileBackedHTTPMetadataProvider, FilesystemMetadataProvider, and ResourceBackedMetadataProvider):

Name	Type	Default	Description
`parserPoolRef`	Bean ID	shibboleth.ParserPool	Identifies a Spring bean for the XML parser used to parse 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 `Set<MetadataIndex>` used to support resolution of metadata based on criteria other than an entityID.
`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.
