protected int curIdx

Constructor Detail

PojoIterator

public PojoIterator(DataModel parent,
                    PojoDataSource ds)

Creates a new instance of PojoIterator.

Parameters:

parent - the parent model node wich pojo is expected to be a collection

ds - the data source object

Method Detail

get

public java.lang.Object get(java.lang.String element)

Description copied from class: PojoModel

Get the value of the element located at the path in the element parameter. The element name parameter can include an attribute name by appending '@attributeName' to the path, where attributeName is the name of the attribute.

Overrides:

get in class PojoModel

Parameters:

element - The path to the DataModel required

Returns:

The value of the DataModel or the attribute

sync

public void sync()

Syncs this node with the collection stored in the parent node

Overrides:

sync in class PojoModel

current

public java.lang.Object current()

Returns the model node wrapping the current element in the iteration

Specified by:

current in interface Iterator

Returns:

current element

hasNext

public boolean hasNext()

Indicates whether the iterator has more elements

Specified by:

hasNext in interface Iterator

Returns:

true if the iterator has more elements, false otherwise.

next

public java.lang.Object next()

Gets the model node wrapping the next element in the iterated collection

Specified by:

next in interface Iterator

Returns:

the next element in the iteration if there is one or the current element if there is no more elements in the iteration.

first

public java.lang.Object first()

Returns the model node wrapping the first object from the iterated collection and resets the iteration index to 0

Specified by:

first in interface Iterator

Returns:

first element of the iteration

last

public java.lang.Object last()

Returns the model node wrapping the last element of the iterated collection

Specified by:

last in interface Iterator

Returns:

iteration last element

hasPrevious

public boolean hasPrevious()

Indicates whether this iterator has more elements while traversing the iterated collection in the reverse direction

Specified by:

hasPrevious in interface Iterator

Returns:

true if the iterator has more elements, false otherwise

previous

public java.lang.Object previous()

Returns the model node wrapping the previous element in the iteration.

Specified by:

previous in interface Iterator

Returns:

previous element

getId

public java.lang.String getId()

Gets the values of the ID attribute

Overrides:

getId in class PojoModel

Returns:

the ID attribute
