Constructor Detail

OwStandardObjectCollection

public OwStandardObjectCollection()

Method Detail

sort

public void sort(OwSort sortCriteria_p)
          throws Exception

sort the list by the given criteria. The default implementation sorts on the cached objects in the application server. The function may be overloaded to sort by the ECM System with SQL sort statements.

Specified by:

sort in interface OwObjectCollection

Parameters:

sortCriteria_p - list of sortcriteria

Throws:

Exception

isComplete

public boolean isComplete()
                   throws Exception

check if object list has retrieved all objects If false, there are more objects available, but it is not guaranteed that you can retrieve them with the next / prev functions. I.e. hasNext / Prev might still return false.

Specified by:

isComplete in interface OwObjectCollection

Returns:

boolean true = all available objects have been added to the list

Throws:

Exception

setComplete

public void setComplete(boolean fComplete_p)

set the complete flag

hasNext

public boolean hasNext()
                throws Exception

overridable to check if object list has access to more next objects, than currently added. I.e. if it could do another SQL Query and obtain more objects from the ECM System.

Specified by:

hasNext in interface OwObjectCollection

Returns:

boolean true = there are more objects available, call getMore() to retrieve additional objects.

Throws:

Exception

hasPrev

public boolean hasPrev()
                throws Exception

overridable to check if object list has access to more previous objects, than currently added. I.e. if it could do another SQL Query and obtain more objects from the ECM System.

Specified by:

hasPrev in interface OwObjectCollection

Returns:

boolean true = there are more objects available, call getMore() to retrieve additional objects.

Throws:

Exception

getNext

public void getNext()
             throws Exception

overridable to retrieve further objects, than currently added. I.e. submit another SQL Query and obtain more objects from the ECM System. NOTE: The retrieved objects will replace the current objects in the list

Specified by:

getNext in interface OwObjectCollection

Throws:

Exception

getPrev

public void getPrev()
             throws Exception

overridable to retrieve further objects, than currently added. I.e. submit another SQL Query and obtain more objects from the ECM System. NOTE: The retrieved objects will replace the current objects in the list

Specified by:

getPrev in interface OwObjectCollection

Throws:

Exception

getAttribute

public Object getAttribute(int iIndex_p)
                    throws Exception

get a object at the specified index or throws OwObjectNotFoundException

Specified by:

getAttribute in interface OwAttributeBag

Parameters:

iIndex_p - int index

Returns:

Object

Throws:

Exception

getSafeAttribute

public Object getSafeAttribute(String strName_p,
                               Object default_p)

get the attribute with the given name, returns default if not found.

Specified by:

getSafeAttribute in interface OwAttributeBag

getAttribute

public Object getAttribute(String strName_p)
                    throws Exception

get the attribute with the given name

Specified by:

getAttribute in interface OwAttributeBag

Throws:

Exception

setAttribute

public void setAttribute(String strName_p,
                         Object object_p)
                  throws Exception

set the attribute with the given name

Throws:

Exception

hasAttribute

public boolean hasAttribute(String strName_p)

check if attribute exists

Specified by:

hasAttribute in interface OwAttributeBag

getAttributeNames

public Collection getAttributeNames()

get all attribute names in the bag

Specified by:

getAttributeNames in interface OwAttributeBag

attributecount

public int attributecount()

Description copied from interface: OwAttributeBag

get the number of attributes, or -1 if unknown

Specified by:

attributecount in interface OwAttributeBag
