    public void setRoleDisabledIcon(java.lang.String iconDisabled)

### getAvailableRoleItems

    public java.util.List getAvailableRoleItems()

  Returns all the items that are candidates for assignment to the role. This list should only include an item that is already assigned if it makes sense to assign the item multiple times.

  Specified by:
    `getAvailableRoleItems` in interface `com.sas.util.RoleInterface`
  Returns:
    the available items
  See Also:
    `getRoleItems()`

### getRoleItems

    public java.util.List getRoleItems()

  Returns the items that have been assigned to the role.

                             int offset)

  Specified by:
    `moveRoleItem` in interface `com.sas.util.RoleInterface`

### addRoleItem

    public void addRoleItem(java.lang.Object item)

  Assigns the given item to the role. Should not fail if caller has honored the information provided by `getAvailableRoleItems()`,`getMinRoleItemCount()`, and `getMaxRoleItemCount()`. After calling caller should recall these other methods since assigning one item may make another invalid for assignment and/or otherwise change the assignment rules. This method will create a DataItemReference for any item that is in the InformationMap but not in the dataSelection. This is necessary for persistence of item attributes since map item attribues cannot be changed at runtime.

  Specified by:
    `addRoleItem` in interface `com.sas.util.RoleInterface`
  Parameters:
    `item` - the item to assign
  See Also:
    `addRoleItems(java.util.List)`, `removeRoleItem(java.lang.Object)`

### addRoleItem

    public void addRoleItem(java.lang.Object item,
                            java.util.List availableRoleItems)

  Assigns the given item to the role. Should not fail if caller has honored the information provided by `getAvailableRoleItems()`, `getMinRoleItemCount()`, and `getMaxRoleItemCount()`. After calling caller should recall these other methods since assigning one item may make another invalid for assignment and/or otherwise change the assignment rules. This method will create a DataItemReference for any item that is in the InformationMap but not in the dataSelection. This is necessary for persistence of item attributes since map item attribues cannot be changed at runtime.

  Parameters:
    `item` - the item to assign
  See Also:
    `addRoleItems(java.util.List)`, `removeRoleItem(java.lang.Object)`, `DataItemReference`

### addRoleItems

    public java.util.List addRoleItems(java.util.List items)

  Assigns the given items to the role.

  This is a convenience method for consecutive calls to `addRoleItem()`, but saves the caller the trouble of requerying `getAvailableRoleItems()`, `getMinRoleItemCount()`, and `getMaxRoleItemCount()` and validating the returned results against the remaining items to be added.

  Specified by:
    `addRoleItems` in interface `com.sas.util.RoleInterface`
  Parameters:
    `items` - the items to assign
  Returns:
    `null` if all items added, otherwise a list of the items that could not be added
  See Also:
    `addRoleItem(java.lang.Object)`

### removeRoleItem

    public void removeRoleItem(java.lang.Object item)

  Unassigns the given item from the role. After calling caller should recall `getAvailableRoleItems()`, `getMinRoleItemCount()`, and `getMaxRoleItemCount()` since unassigning one item may make another valid for assignment and/or otherwise change the assignment rules.

  Specified by:
    `removeRoleItem` in interface `com.sas.util.RoleInterface`
  Parameters:
    `item` - the item to unassign
  See Also:
    `addRoleItem(java.lang.Object)`, `removeAllRoleItems()`

### removeAllRoleItems

    public void removeAllRoleItems()

  Unassigns all items from the role. After calling caller should recall `getAvailableRoleItems()`, `getMinRoleItemCount()`, and `getMaxRoleItemCount()` since unassigning one item may make another valid for assignment and/or otherwise change the assignment rules.

  Specified by:
    `removeAllRoleItems` in interface `com.sas.util.RoleInterface`
  See Also:
    `removeRoleItem(java.lang.Object)`

### toString

    public java.lang.String toString()

  Overrides:
    `toString` in class `java.lang.Object`
