Constructor Detail

XPojoIterator

public XPojoIterator(XModel parent,
                     XPojoDataSource ds)

Creates a new instance of XPojoIterator.

Parameters:

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

ds - the data source object

Method Detail

sync

public void sync()

Specified by:

current in interface XIterator

Returns:

current element

hasNext

public boolean hasNext()

Indicates whether the iterator has more elements

Specified by:

hasNext in interface XIterator
