CompoundAccessController

public CompoundAccessController(AccessController a_accessController)
                         throws WTPropertyVetoException

Supported API: false

Parameters:

a_accessController -

Throws:

WTPropertyVetoException

Method Detail

getMaxCount

public int getMaxCount()

Gets the value of the attribute: maxCount.

Supported API: false

Returns:

int

setMaxCount

public void setMaxCount(int a_MaxCount)

Sets the value of the attribute: maxCount.

Supported API: false

Parameters:

a_MaxCount -

checkAccess

public boolean checkAccess(Object a_object)
                    throws PersistenceException

Check access of the object. Return false if the current principal does not have READ permission on all of the objects. This method is implemented by call the Access Control service hasAccess() method.

Supported API: false

Specified by:

checkAccess in interface AccessController

Overrides:

checkAccess in class AccessControllerAdapter

Parameters:

a_object -

Returns:

boolean

Throws:

PersistenceException

getItemBuilders

public Vector getItemBuilders(Vector a_tableInfos,
                              ResultBuilder a_resultBuilder,
                              int a_itemOffset)
                       throws PersistenceException

Return a Vector of ItemBuilders that will be used to retrieve Access Control related objects. For each existing ItemBuilder, if Access Control is not supplied for that Item, then a surrogate ItemBuilder is added.

Supported API: false

Specified by:

getItemBuilders in interface AccessController

Overrides:

getItemBuilders in class AccessControllerAdapter

Parameters:

a_tableInfos - Vector of concrete TableExpression instances to use to create the Access Control items

a_resultBuilder - instance used to create the Access Control items

a_itemOffset - The current offset where the items will be placed in the results.

Returns:

Vector

Throws:

PersistenceException

Retrun a ItemBuilders that will be used to retrieve Access Control related objects.

Supported API: false

Specified by:

getViewItemBuilder in interface AccessController

Overrides:

getViewItemBuilder in class AccessControllerAdapter

Parameters:

a_classInfo -

a_alias -

Returns:

ItemBuilder
