org.opensaml.saml.metadata.resolver.impl.TemplateRequestURLBuilder

All Implemented Interfaces:

Function<CriteriaSet,String>

public class TemplateRequestURLBuilder
extends Object
implements Function<CriteriaSet,String>

Function which produces a URL by substituting an entity ID value from criteria into a Velocity template string.

The entity ID will be replaced in the template string according to the template variable entityID, e.g. "https://metadataservice.com/entity/${entityID}".

The value of the encodingStyle parameter determines whether and how the entity ID will be encoded prior to substitution, and accepts an enum value from TemplateRequestURLBuilder.EncodingStyle. Legacy deprecated constructors accept an encoded parameter, where true means TemplateRequestURLBuilder.EncodingStyle.form and false means TemplateRequestURLBuilder.EncodingStyle.none.
