Method Detail

getCurrentGlobalVariables

public static GlobalVariables getCurrentGlobalVariables()

injectGlobalVariables

public static void injectGlobalVariables(GlobalVariables globalVariables)

popGlobalVariables

public static GlobalVariables popGlobalVariables()

getUserSession

public static UserSession getUserSession()

Returns:

the UserSession that has been assigned to this thread of execution it is important that this not be called by anything that lives outside

setHideSessionFromTestsMessage

public static void setHideSessionFromTestsMessage(String message)

Sets an error message for tests that try to use the session without declaring it. This method should be use by only KualiTestBase, not by other test code and especially not by production code.

Parameters:

message - the detail to throw, or null to allow access to the session

setUserSession

public static void setUserSession(UserSession userSession)

sets the userSession object into the global variable for this thread

Parameters:

userSession -

getMessageMap

public static MessageMap getMessageMap()

public static void mergeErrorMap(MessageMap messageMap)

Merges a message map into the global variables error map

Parameters:

messageMap -

setMessageMap

public static void setMessageMap(MessageMap messageMap)

Sets a new (clean) MessageMap

Parameters:

messageMap -

getRequestCache

setRequestCache

public static void setRequestCache(String cacheName,
                   Object cacheObject)

getUifFormManager

public static UifFormManager getUifFormManager()

Retrieves the UifFormManager which can be used to store and remove forms from the session

Returns:

UifFormManager

setUifFormManager

public static void setUifFormManager(UifFormManager uifFormManager)

Sets a UifFormManager for the current thread

Parameters:

uifFormManager -

Sets a new (clean) AuditErrorList

Parameters:

errorMap -

clear

Type Parameters:

T - callable return type

Parameters:

callable - the code to run under a new set of GlobalVariables

Returns:

return value from callable

Throws:

Exception - from Callable.call()

doInNewGlobalVariables
