Method Details

getViewIndexFor

public static int getViewIndexFor(@Nullable TransformationList<?,?> transformationList,
 int index)

Maps the given index of the transformation lists direct source list to an index in the transformation list. Returns a negative value, if the source index is not mapped. This method is also a workaround for undefined index-out-of-bounds behavior of TransformationList.getViewIndex(int).

Parameters:

transformationList - the given transformation list

index - the given source list index

Returns:

the corresponding transformation list index

Throws:

IllegalArgumentException - if the source list is not in the transformation chain

Since:

2.0
