Interface StateAdminSession

All Superinterfaces:

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

public interface StateAdminSession
extends OsidSession

This session creates, updates, and deletes States. 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 State, a StateForm is requested using getStateFormForCreate() specifying the desired relationship peers and record Types or none if no record Types are needed. The returned StateForm 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 StateForm is submiited to a create operation, it cannot be reused with another create operation unless the first operation was unsuccessful. Each StateForm corresponds to an attempted transaction.

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

The delete operations delete States. To unmap a State from the current Process, the StateProcessAssignmentSession should be used. These delete operations attempt to remove the State itself thus removing it from all known Process catalogs.

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

Method Detail

getProcessId

Id getProcessId()

Gets the Process Id associated with this session.

Returns:

the Process Id associated with this session

Compliance:

mandatory - This method must be implemented.

getProcess

Process getProcess()
                   throws OperationFailedException,
                          PermissionDeniedException

Gets the Process associated with this session.

Returns:

the Process associated with this session

Throws:

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

canCreateStates

boolean canCreateStates()

Tests if this user can create States. A return of true does not guarantee successful authorization. A return of false indicates that it is known creating a State 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 State creation is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

canCreateStateWithRecordTypes

boolean canCreateStateWithRecordTypes(Type[] stateRecordTypes)

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

Parameters:

stateRecordTypes - array of state record types

Returns:

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

Throws:

NullArgumentException - stateRecordTypes is null

Compliance:

mandatory - This method must be implemented.

getStateFormForCreate

StateForm getStateFormForCreate(Type[] stateRecordTypes)
                                throws OperationFailedException,
                                       PermissionDeniedException

Gets the state form for creating new states. A new form should be requested for each create transaction.

Parameters:

stateRecordTypes - array of state record types

Returns:

the state form

Throws:

NullArgumentException - stateRecordTypes 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.

createState

State createState(StateForm stateForm)
                  throws OperationFailedException,
                         PermissionDeniedException

Creates a new State.

Parameters:

stateForm - the form for this State

Returns:

the new State

Throws:

IllegalStateException - stateForm already used in a create transaction

InvalidArgumentException - one or more of the form elements is invalid

NullArgumentException - stateForm is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - stateForm did not originate from getStateFormForCreate()

Compliance:

mandatory - This method must be implemented.

canUpdateStates

boolean canUpdateStates()

Tests if this user can update States. A return of true does not guarantee successful authorization. A return of false indicates that it is known updating a State 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 State modification is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

getStateFormForUpdate

StateForm getStateFormForUpdate(Id stateId)
                                throws NotFoundException,

                                       PermissionDeniedException

Gets the state form for updating an existing state. A new state form should be requested for each update transaction.

Parameters:
