Class TemplateRequestURLBuilder

java.lang.Object

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

All Implemented Interfaces:

Function<String,String>

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

Function which produces a URL by substituting a an entity ID value 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}".

If the value of the encoded parameter is true then the entity ID will be URL encoded prior to substitution. Otherwise, the literal value of the entity ID will be substituted.
