Field Detail

parameter

final AvaticaParameter parameter

calendar

final Calendar calendar

Calendar is not thread-safe. But calendar is only used from within one thread, and we have to trust that clients are not modifying calendars that they pass to us in a method such as PreparedStatement.setTime(int, Time, Calendar), so we do not need to synchronize access.

index

private final int index

slots

final TypedValue[] slots

DUMMY_VALUE

public static final Object DUMMY_VALUE

Value that means the parameter has been set to null. If value is null, parameter has not been set.
