MetadataProviderReloadingAttributes

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

Name	Type	Default	Description

Name	Type	Default	Description
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.
expirationWarningThreshold	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.
indexesRef	Bean ID		Bean ID of a Set<MetadataIndex> used to support resolution of metadata based on criteria other than an entityID, e.g. resolving by protocol endpoint for CAS or by SAML Artifact source ID.
resolveViaPredicatesOnly	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
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 Timer used to schedule reloads. When not set, an internal one is created. Generally should not be changed.
