Interface InputAdminSession

All Superinterfaces:

AutoCloseable, Closeable, OsidSession, OsidSession

All Known Subinterfaces:

InputBatchAdminSession

public interface InputAdminSession
extends OsidSession

This session creates, updates, and deletes Inputs . 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 Input , a InputForm is requested using getInputFormForCreate() specifying the desired device, controller, and record Types or none if no record Types are needed. The returned InputForm 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 InputForm is submiited to a create operation, it cannot be reused with another create operation unless the first operation was unsuccessful. Each InputForm corresponds to an attempted transaction.

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

The delete operations delete Inputs . To unmap a Input from the current System , the InputSystemAssignmentSession should be used. These delete operations attempt to remove the Input itself thus removing it from all known System catalogs.

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

Method Details

getSystemId

Id getSystemId()

Gets the System Id associated with this session.

Returns:

the System Id associated with this session

Compliance:

mandatory - This method must be implemented.

getSystem

System getSystem()
          throws OperationFailedException,
PermissionDeniedException

Gets the System associated with this session.

Returns:

the system

Throws:

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

canCreateInputs

boolean canCreateInputs()

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

Compliance:

mandatory - This method must be implemented.

canCreateInputWithRecordTypes

boolean canCreateInputWithRecordTypes(Type[] inputRecordTypes)

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

Parameters:

inputRecordTypes - array of input record types

Returns:

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

Throws:

NullArgumentException - inputRecordTypes is null

Compliance:

mandatory - This method must be implemented.

getInputFormForCreate

InputForm getInputFormForCreate(Id deviceId,
 Id controllerId,
 Type[] inputRecordTypes)
                         throws NotFoundException,
OperationFailedException,
PermissionDeniedException

Gets the input form for creating new inputs. A new form should be requested for each create transaction.

Parameters:

deviceId - a device Id

controllerId - a controller Id

inputRecordTypes - array of input record types

Returns:

the input form

Throws:

NotFoundException - deviceId or controllerId is not found

NullArgumentException - deviceId, controllerId , or inputRecordTypes 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.

Input createInput(InputForm inputForm)
           throws OperationFailedException,
