Method Detail

applyFilter

public void applyFilter(Map<Integer,Object> filterIndexToObjectMap)

Create GlazedLists matcher editors and apply them to facilitate filtering.

Specified by:

applyFilter in interface IFilterStrategy<T>

Parameters:

filterIndexToObjectMap - A Map of column indexes to filter text Strings.

getStringFromColumnObject

protected String getStringFromColumnObject(int columnIndex,
