Interface ServiceLocationAttributeVerifier

public interface ServiceLocationAttributeVerifier

The ServiceLocationAttributeVerifier provides access to service templates. Classes implementing this interface parse SLP template definitions, provide information on attribute definitions for service types, and verify whether a ServiceLocationAttribute object matches a template for a particular service type. Clients obtain ServiceLocationAttributeVerifier objects for specific SLP service types through the TemplateRegistry.

Method Summary

Methods

Modifier and Type	Method and Description
ServiceLocationAttributeDescriptor	getAttributeDescriptor(java.lang.String pAttributeId) Return the ServiceLocationAttributeDescriptor for the attribute having the named id.
java.util.Enumeration	getAttributeDescriptors() Returns an Enumeration allowing introspection on the attribute definition in the service template.
java.lang.String	getDescription() Return the descriptive help text for the template.
java.util.Locale	getLocale() Return the language locale of the template.
ServiceType	getServiceType() Returns the SLP service type for which this is the verifier.
java.lang.String	getURLSyntax() Return the URL syntax expression for the service: URL.
java.lang.String	getVersion() Return the template version number identifier.
void	verifyAttribute(ServiceLocationAttribute pAttribute) Verify that the attribute matches the template definition.
void	verifyRegistration(java.util.Vector pAttributeVector) Verify that the Vector of ServiceLocationAttribute objects matches the template for this service type.

Method Detail

getServiceType

ServiceType getServiceType()

Returns the SLP service type for which this is the verifier.

Returns:

The service type

getLocale

java.util.Locale getLocale()

Return the language locale of the template.

Returns:

The locale

getVersion

java.lang.String getVersion()

Return the template version number identifier.

Returns:

The version

getURLSyntax

java.lang.String getURLSyntax()

Return the URL syntax expression for the service: URL.

Returns:

The url syntax

getDescription

java.lang.String getDescription()

Return the descriptive help text for the template.

Returns:

The description

getAttributeDescriptor

ServiceLocationAttributeDescriptor getAttributeDescriptor(java.lang.String pAttributeId)

Return the ServiceLocationAttributeDescriptor for the attribute having the named id. If no such attribute exists in this template, return null. This method is primarily for GUI tools to display attribute information. Programmatic verification of attributes should use the verifyAttribute() method.

Parameters:

pAttributeId - The attribute id

Returns:

The descriptor

getAttributeDescriptors

java.util.Enumeration getAttributeDescriptors()

Returns an Enumeration allowing introspection on the attribute definition in the service template. The Enumeration returns ServiceLocationAttributeDescriptor objects for the attributes. This method is primarily for GUI tools to display attribute information. Programmatic verification of attributes should use the verifyAttribute() method.

Returns:

Enumeration of attribute descriptors

verifyAttribute

void verifyAttribute(ServiceLocationAttribute pAttribute)
                     throws ServiceLocationException

Verify that the attribute matches the template definition. If the attribute doesn't match, ServiceLocationException is thrown with the error code as ServiceLocationException.PARSE_ERROR.

Parameters:

pAttribute - The ServiceLocationAttribute object to be verified.

Throws:

ServiceLocationException - if validation failed

verifyRegistration

void verifyRegistration(java.util.Vector pAttributeVector)
                        throws ServiceLocationException

Verify that the Vector of ServiceLocationAttribute objects matches the template for this service type. The vector must contain all the required attributes, and all attributes must match their template definitions. If the attributes don't match, ServiceLocationException is thrown with the error code as ServiceLocationException.PARSE_ERROR

Parameters:

pAttributeVector - A Vector of ServiceLocationAttribute objects for the registration.

Throws:

ServiceLocationException - if attributes don't match
