Class TemplateRegistry

java.lang.Object
org.sblim.slp.TemplateRegistry

public abstract class TemplateRegistry extends Object
Subclasses of the TemplateRegistry abstract class provide access to service location templates [8]. Classes implementing TemplateRegistry perform a variety of functions. They manage the registration and access of service type template documents. They create attribute verifiers from service templates, for verification of attributes and introspection on template documents. Note that clients of the Advertiser are not required to verify attributes before registering (though they may get a TYPE_ERROR if the implementation supports type checking and there is a mismatch with the template).
