The actual type of the collection may be one of the following:

• collection ( use COLLECTION )
• set ( use SET ) which contains unique elements
• list ( use LIST ) which is ordered

createItem

protected Item createItem(SessionContext ctx,
                          ComposedType type,
                          Item.ItemAttributeMap allAttributes)
                   throws JaloBusinessException

Generic item creation method.

Requires the following attributes:

• Type.CODE
• ELEMENT_TYPE

Optionally the type of collection may be defined by TYPE_OF_COLLECTION.

Specified by:

createItem in class Item

Parameters:

ctx - the current session context which this item is created within

type - the actual item type ( since subtypes may not provide a own jalo class this may be different from the type which this method was implemented for )

Returns:

the new item instance

Throws:

JaloBusinessException - indicates an error during creation - any changes will be rollbacked

getNonInitialAttributes

protected Item.ItemAttributeMap getNonInitialAttributes(SessionContext ctx,
                                                        Item.ItemAttributeMap allAttributes)

Cuts the following attribute values which are already set during actual item creation:

• Type.CODE
• ELEMENT_TYPE
• TYPE_OF_COLLECTION

Overrides:

getNonInitialAttributes in class Item

Parameters:

ctx - session context with language = NULL

allAttributes - a ItemAttributeMap contaning attribute values.

Returns:

a ItemAttributeMap containing all attribute values, which belong to non-initial attributes.

toString

public String toString(SessionContext ctx,
                       Object value)

Internal access to persistence layer implementation.

isAssignableFrom

type - the type to be checked.

See Also:

isTypeAssignableFrom(int, int)

isInstance

public boolean isInstance(Object o)

Tests if a given object is instance of this collection type. This checks the type of collection and each element of being instance of the element type.

Since all elements are checked this method is considerably costly so use with care!
