Class TypeQualifiers

  net.java.ao.types.TypeQualifiers

public class TypeQualifiers
extends Object

Describes optional modifiers to a type: string length for string types, precision and scale for numeric types. Each TypeInfo may have default qualifiers set by the database provider; qualifiers may also be modified by annotations.

Field Summary

static int	MAX_STRING_LENGTH Maximum string length (for strings of limited length) cannot be set to greater than this value.
static int	UNLIMITED_LENGTH If stringLength is set to this constant, the field is an unlimited-length string (TEXT, CLOB, or LONG VARCHAR).
