Description copied from interface: ISortedColumns

Adds all the columns of a given column map to this column map. This is equivalent to: for (Column c : cm) add(c); but is potentially faster.

Specified by:

addAll in interface ISortedColumns

isEmpty

public boolean isEmpty()

Description copied from interface: ISortedColumns

Returns true if this map is empty, false otherwise.

Specified by:

isEmpty in interface ISortedColumns

getEstimatedColumnCount

public int getEstimatedColumnCount()

Specified by:

getEstimatedColumnCount in interface IIterableColumns
