Constructor & Destructor Documentation

opensaml::saml2md::AbstractMetadataProvider::AbstractMetadataProvider ( const xercesc::DOMElement * e = nullptr )

protected

Constructor.

If a DOM is supplied, a set of default logic will be used to identify and build a KeyInfoResolver plugin and install it into the provider.

The following XML content is supported:

<KeyInfoResolver> elements with a type attribute

XML namespaces are ignored in the processing of these elements.

Parameters

e	DOM to supply configuration for provider

Member Function Documentation

virtual void opensaml::saml2md::AbstractMetadataProvider::clearDescriptorIndex ( bool freeSites = false )

protectedvirtual

Clear the cache of known entities and groups.

Parameters

freeSites true iff the objects cached in the site map should be freed.

const EntitiesDescriptor* opensaml::saml2md::AbstractMetadataProvider::getEntitiesDescriptor	(	const char *	name,
		bool	requireValidMetadata = `true`
	)		const

virtual

Gets the metadata for a given group of entities.

If a valid group is returned, the resolver will be left in a locked state. The caller MUST unlock the resolver when finished with the group.

Parameters

name	the name of the group
requireValidMetadata	indicates whether the metadata for the group must be valid/current

Returns: the group's metadata or nullptr if there is no metadata or no valid metadata

Implements opensaml::saml2md::MetadataProvider.

std::pair<const EntityDescriptor*,const RoleDescriptor*> opensaml::saml2md::AbstractMetadataProvider::getEntityDescriptor ( const Criteria & criteria ) const

virtual

Gets entity metadata based on supplied criteria.

If a valid entity is returned, the provider will be left in a locked state. The caller MUST unlock the provider when finished with the entity.

Parameters

criteria lookup criteria

Returns: the entity's metadata (and optionally a role) or nullptr if there is no qualifying metadata

Implements opensaml::saml2md::MetadataProvider.

Reimplemented in opensaml::saml2md::DynamicMetadataProvider.

virtual void opensaml::saml2md::AbstractMetadataProvider::index	(	EntityDescriptor *	site,
		time_t	validUntil,
		bool	replace = `false`
	)		const

protectedvirtual

Deprecated:: Loads an entity into the cache for faster lookup.

This includes processing known reverse lookup strategies for artifacts.

Parameters

site	entity definition
validUntil	maximum expiration time of the entity definition
replace	true iff existing entries for the same entity should be cleared/replaced

virtual void opensaml::saml2md::AbstractMetadataProvider::index	(	EntitiesDescriptor *	group,
		time_t	validUntil
	)		const

protectedvirtual

Deprecated:: Loads a group of entities into the cache for faster lookup.

Parameters

group	group definition
validUntil	maximum expiration time of the group definition

virtual void opensaml::saml2md::AbstractMetadataProvider::indexEntity	(	EntityDescriptor *	site,
		time_t &	validUntil,
		bool	replace = `false`
	)		const

protectedvirtual

Loads an entity into the cache for faster lookup.

This includes processing known reverse lookup strategies for artifacts. The validUntil parameter will contain the smallest value found on output.

Parameters

site	entity definition
validUntil	maximum expiration time of the entity definition
replace	true iff existing entries for the same entity should be cleared/replaced

virtual void opensaml::saml2md::AbstractMetadataProvider::indexGroup	(	EntitiesDescriptor *	group,
		time_t &	validUntil
	)		const

protectedvirtual

Loads a group of entities into the cache for faster lookup.

The validUntil parameter will contain the smallest value found on output.

Parameters

group	group definition
validUntil	maximum expiration time of the group definition

void opensaml::saml2md::AbstractMetadataProvider::outputStatus ( std::ostream & os ) const

virtual

Generate an XML representation of the provider's status.

The XML must be well-formed, but is otherwise arbitrary.

Parameters

os	stream to write status information to

Reimplemented from opensaml::saml2md::MetadataProvider.
