setValueFrom

public void setValueFrom(ColumnValueSelector<?> selector)

Specified by:

setValueFrom in interface SettableColumnValueSelector<Long>

setValue

public void setValue(long value)

Optimized method for assigning timestamps, that are known to never be null

getLong

public long getLong()

Specified by:

getLong in interface BaseLongColumnValueSelector

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.
