Interface ParameterQuerySession

All Superinterfaces:

java.lang.AutoCloseable, java.io.Closeable, OsidSession

All Known Subinterfaces:

ParameterSearchSession

public interface ParameterQuerySession
extends OsidSession

This session provides methods for searching Parameter objects. The search query is constructed using the ParameterQuery.

Two views of the configuration data are defined;

• federated: parameters defined in configurations that are a parent of this configuration in the configuration hierarchy are included
• isolated: parameters are contained to within this configuration

Method Summary

Methods

Modifier and Type	Method and Description

Id	getConfigurationId() Gets the Configuration Id associated with this session.
ParameterQuery	getParameterQuery() Gets a paraameter query.
ParameterList	getParametersByQuery(ParameterQuery parameterQuery) Gets a list of Parameters matching the given query.
void	useFederatedConfigurationView() Federates the view for methods in this session.
void	useIsolatedConfigurationView() Isolates the view for methods in this session.

Method Detail

getConfigurationId

Id getConfigurationId()

Gets the Configuration Id associated with this session.

Returns:

the Configuration Id associated with this session

Compliance:

mandatory - This method must be implemented.

getConfiguration

Configuration getConfiguration()
                               throws OperationFailedException,
                                      PermissionDeniedException

Gets the Configuration associated with this session.

Returns:

the Configuration associated with this session

Throws:

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

canSearchParameters

boolean canSearchParameters()

Tests if this user can perform Parameter searches. A return of true does not guarantee successful authorization. A return of false indicates that it is known all methods in this session will result in a PERMISSION_DENIED. This is intended as a hint to an application that may opt not to offer search operations to unauthorized users.

Returns:

false if lookup methods are not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

useFederatedConfigurationView

void useFederatedConfigurationView()

Federates the view for methods in this session. A federated view will include parameters from parent configurations in the configuration hierarchy.

Compliance:

mandatory - This method is must be implemented.

useIsolatedConfigurationView

void useIsolatedConfigurationView()

Isolates the view for methods in this session. An isolated view restricts searches to this configuration only.

Compliance:

mandatory - This method is must be implemented.

getParameterQuery

ParameterQuery getParameterQuery()

Gets a paraameter query.

Returns:

the parameter query

Compliance:

mandatory - This method must be implemented.

getParametersByQuery

ParameterList getParametersByQuery(ParameterQuery parameterQuery)
                                   throws OperationFailedException,
                                          PermissionDeniedException

Gets a list of Parameters matching the given query.

Parameters:

parameterQuery - the parameter query

Returns:

the returned ParameterList

Throws:

NullArgumentException - parameterQuery is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - a query form is not of this service

Compliance:

mandatory - This method must be implemented.
