Interface ParameterAdminSession

All Superinterfaces:

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

All Known Subinterfaces:

ParameterBatchAdminSession

public interface ParameterAdminSession
extends OsidSession

This session creates, updates, and deletes Parameters. The data for create and update is provided by the consumer via the form object. OsidForms are requested for each create or update and may not be reused.

Create and update operations differ in their usage. To create a Parameter, a ParameterForm is requested using getParameterFormForCreate() specifying the desired relationship peers and record Types or none if no record Types are needed. The returned ParameterForm will indicate that it is to be used with a create operation and can be used to examine metdata or validate data prior to creation. Once the ParameterForm is submiited to a create operation, it cannot be reused with another create operation unless the first operation was unsuccessful. Each ParameterForm corresponds to an attempted transaction.

For updates, ParameterForms are requested to the Parameter Id that is to be updated using getParameterFormForUpdate(). Similarly, the ParameterForm has metadata about the data that can be updated and it can perform validation before submitting the update. The ParameterForm can only be used once for a successful update and cannot be reused.

The delete operations delete Parameters. To unmap a Parameter from the current Configuration, the ParameterConfigurationAssignmentSession should be used. These delete operations attempt to remove the Parameter itself thus removing it from all known Configuration catalogs.

This session includes an Id aliasing mechanism to assign an external Id to an internally assigned Id.

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.

canCreateParameters

boolean canCreateParameters()

Tests if this user can create Parameters. A return of true does not guarantee successful authorization. A return of false indicates that it is known creating a Parameter will result in a PERMISSION_DENIED. This is intended as a hint to an application that may opt not to offer create operations to an unauthorized user.

Returns:

false if Parameter creation is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

canCreateParameterWithRecordTypes

boolean canCreateParameterWithRecordTypes(Type[] parameterRecordTypes)

Tests if this user can create a single Parameter using the desired record types. While ConfigurationManager.getParameterRecordTypes() can be used to examine which records are supported, this method tests which record(s) are required for creating a specific Parameter. Providing an empty array tests if a Parameter can be created with no records.

Parameters:

parameterRecordTypes - array of parameter record types

Returns:

true if Parameter creation using the specified record Types is supported, false otherwise

Throws:

NullArgumentException - parameterRecordTypes is null

Compliance:

mandatory - This method must be implemented.

getParameterFormForCreate

ParameterForm getParameterFormForCreate(Type[] parameterRecordTypes)
                                        throws OperationFailedException,
                                               PermissionDeniedException

Gets the paramater form for creating new parameters.

Parameters:

parameterRecordTypes - array of parameter record types

Returns:

the parameter form

Throws:

NullArgumentException - configurationRecordTypes is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - unable to get form for requested record types

Compliance:

mandatory - This method must be implemented.

createParameter

Parameter createParameter(ParameterForm parameterForm)
                          throws OperationFailedException,
                                 PermissionDeniedException

Creates a new Parameter.

Parameters:

parameterForm - the form for this Parameter

Returns:

the new Parameter

Throws:

IllegalStateException - parameterForm already used in a create transaction

InvalidArgumentException - one or more of the form elements is invalid

NullArgumentException - parameterForm is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - parameterForm did not originate from getParameterFormForCreate()

Compliance:

mandatory - This method must be implemented.

canUpdateParameters

boolean canUpdateParameters()

Tests if this user can update Parameters. A return of true does not guarantee successful authorization. A return of false indicates that it is known updating a Parameter will result in a PERMISSION_DENIED. This is intended as a hint to an application that may opt not to offer update operations to an unauthorized user.

Returns:

false if Parameter modification is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

getParameterFormForUpdate

ParameterForm getParameterFormForUpdate(Id parameterId)
                                        throws NotFoundException,
