Returns:

iterator

@Transactional(readOnly=true)
public Iterator<? extends P> iterator(int first,
                                                                    int count)

Fetch records Note if first or count < 0 then it will not consider pagination and hence get all records

model

public org.apache.wicket.model.IModel<P> model(P object)

size

@Transactional(readOnly=true)
public int size()

getProductDao

public ProductDao getProductDao()

setProductDao

public void setProductDao(ProductDao productDao)

setQuery

public void setQuery(Query<P> query)

getFilter

public Query<P> getFilter()

Will apply the filter result to remove them from the main result before producing final result.
The filter result must be a subset of the original result else the count will be wrong (lesser than what it should be)

setFilter

public void setFilter(Query<P> filter)

Will apply the filter result to remove them from the main result before producing final result.
The filter result must be a subset of the original result else the count will be wrong (lesser than what it should be)

setJPARawQueries

public void setJPARawQueries(String rawJPAQueryStr,
                             Map<String,Object> rawJPAQueryParams)

If provided will execute the Query directly without consulting query or filter

reset

public void reset()

getDefaultOrderField

public String getDefaultOrderField()

setDefaultOrderField

public void setDefaultOrderField(String defaultOrderField)
