setValueFrom

public void setValueFrom(ColumnValueSelector<?> selector)

setValueFrom in interface SettableColumnValueSelector<Float>

getFloat in interface BaseFloatColumnValueSelector

isNull

public boolean isNull()

Description copied from interface: BaseNullableColumnValueSelector

Returns true if the primitive long, double, or float value returned by this selector should be treated as null. Users of BaseLongColumnValueSelector.getLong(), BaseDoubleColumnValueSelector.getDouble() and BaseFloatColumnValueSelector.getFloat() must check this method first, or else they may improperly use placeholder values returned by the primitive get methods. Users of BaseObjectColumnValueSelector.getObject() should not call this method. Instead, call "getObject" and check if it is null.

isNull in interface BaseNullableColumnValueSelector
