public final class FloatColumnBuilder extends Object
FloatColumn instances. Example:
FloatColumn column = FloatColumn.builder().add(10f).addAll(200f, 300f, 400f).build();Elements appear in the resulting column in the same order they were added to the builder.
Builder instances can be reused; it is safe to call
build multiple times to build multiple columns in
series. Each new column contains all the elements of the ones created before
it.
