Interface RuleAdminSession

All Superinterfaces:

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

public interface RuleAdminSession
extends OsidSession

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

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

The delete operations delete Rules. To unmap a Rule from the current Engine, the RuleEngineAssignmentSession should be used. These delete operations attempt to remove the Rule itself thus removing it from all known Engine catalogs.

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

Method Detail

getEngineId

Id getEngineId()

Gets the Engine Id associated with this session.

Returns:

the Engine Id associated with this session

Compliance:

mandatory - This method must be implemented.

getEngine

Engine getEngine()
                 throws OperationFailedException,
                        PermissionDeniedException

Gets the Engine associated with this session.

Returns:

the Engine associated with this session

Throws:

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

canCreateRules

boolean canCreateRules()

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

Compliance:

mandatory - This method must be implemented.

canCreateRuleWithRecordTypes

boolean canCreateRuleWithRecordTypes(Type[] ruleRecordTypes)

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

Parameters:

ruleRecordTypes - array of rule record types

Returns:

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

Throws:

NullArgumentException - ruleRecordTypes is null

Compliance:

mandatory - This method must be implemented.

getRuleFormForCreate

RuleForm getRuleFormForCreate(Type[] ruleRecordTypes)
                              throws OperationFailedException,
                                     PermissionDeniedException

Gets the rule form for creating new rules. A new form should be requested for each create transaction.

Parameters:

ruleRecordTypes - array of rule record types

Returns:

the rule form

Throws:

NullArgumentException - ruleRecordTypes is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - unable to get form with requested record types

Compliance:

mandatory - This method must be implemented.

createRule

Rule createRule(RuleForm ruleForm)
                throws OperationFailedException,
                       PermissionDeniedException

Creates a new Rule.

Parameters:

ruleForm - the form for this Rule

Returns:

the new Rule

Throws:

IllegalStateException - ruleForm already used in a create transaction

InvalidArgumentException - one or more of the form elements is invalid

NullArgumentException - ruleForm is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - ruleForm did not originate from getRuleFormForCreate()

Compliance:

mandatory - This method must be implemented.

canUpdateRules

boolean canUpdateRules()

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

Compliance:

mandatory - This method must be implemented.

getRuleFormForUpdate

RuleForm getRuleFormForUpdate(Id ruleId)
                              throws NotFoundException,
