Class RegisteredFormatIds

java.lang.Object

org.apache.derby.iapi.services.io.RegisteredFormatIds

public class RegisteredFormatIds
extends java.lang.Object

Registration of TypedFormat classes.

A TypedFormat is registered by placing a class name at the correct place in the correct array, driven by the base format number:

• 2 byte - MIN_TWO_BYTE_FORMAT_ID - TwoByte

The offset from the base format number (0 based) gives the offset in the array.

The class name is either:

• The actual class name of the TypeFormat.
• The name of a class that extends org.apache.derby.iapi.services.io.FormatableInstanceGetter. In this case the monitor will register an instance of the class after calling its setFormatId() method with format id it is registered as.
