public interface TypedFormat

Cloudscape interface for identifying the format id for the stored form of an object. Objects of different classes may have the same format id if:

• The objects read and write the same stored forms.
• The object's getTypeId() method returns the same identifier.
• The objects support all the interfaces the type implies.

Method Summary

int	getTypeFormatId() Get a universally unique identifier for the type of this object.

Method Detail

getTypeFormatId

public int getTypeFormatId()

Get a universally unique identifier for the type of this object.

Returns:

The identifier. (A UUID stuffed in an array of 16 bytes).
