Method Detail

init
protected void init()
Description copied from class:Filter

in classFilter

canFilter()
-
canFilter
protected boolean canFilter()
This is a quickfix for #55-swingx: NPE if sorter is in pipeline. No way to automatically cleanup "from the outside" if the sorter is hooked to a columnIndex which is no longer valid. So we check here for assigned and valid index.PENDING: should be done higher up?
- Returns:
- boolean to indicate whether accessing the values is valid.
-
