Method Details

count

public int count(Map<String,FilterMeta> filterBy)

Description copied from class: LazyDataModel

Counts the all available data for the given filters. In case of SQL, this would execute a "SELECT COUNT ... WHERE ...". In case you dont use SQL and receive both rowCount and data within a single call, this method should just return 0. You must call LazyDataModel.recalculateFirst(int, int, int) and LazyDataModel.setRowCount(int) in your LazyDataModel.load(int, int, java.util.Map, java.util.Map) method.

Specified by:

count in class LazyDataModel<T>

Parameters:

filterBy - a map with all filter information (only relevant for DataTable, not for eg DataView)

Returns:

the data count

load

public List<T> load(int first,
 int pageSize,
 Map<String,SortMeta> sortBy,
 Map<String,FilterMeta> filterBy)

Description copied from class: LazyDataModel

Loads the data for the given parameters.

Specified by:

load in class LazyDataModel<T>

Parameters:

first - the first entry

pageSize - the page size

sortBy - a map with all sort information (only relevant for DataTable, not for eg DataView)

filterBy - a map with all filter information (only relevant for DataTable, not for eg DataView)

Returns:

the data

sort

protected void sort(List<T> values)

filter

protected List<T> filter(List<T> values,
 Map<String,FilterMeta> filterBy)

getRowData

public T getRowData(String rowKey)

Specified by:

getRowData in interface SelectableDataModel<T>

Overrides:

getRowData in class LazyDataModel<T>

getRowKey

public String getRowKey(T obj)

Specified by:

getRowKey in interface SelectableDataModel<T>

Overrides:

getRowKey in class LazyDataModel<T>
