5.7.3. Data type mappings

MetaFactory contains 2 hardcoded maps (javaTypes and hibernateTypes). The maps functionality should be used to modify a built-in map or to add your own map (but this functionality is not implemented yet).

The following maps are defined by MetaFactory:

• javaTypes - maps pattern type (key) to java type (value)

• hibernateTypes - maps pattern type (key) to hibernate type (value)

Table 5.62 javaTypes

Pattern type	Java type
big_decimal	java.math.BigDecimal
binary	byte[]
blob	java.sql.Blob
boolean	boolean
byte	byte
calendar_date	java.util.Calendar
calendar	java.util.Calendar
character	Character
clob	java.sql.Clob
Date	java.util.Date
DateTime	java.util.Date
double	double
Double	Double
float	float
Float	Float
int	int
integer	int
Integer	Integer
long	long
Long	Long
short	short
String	String
text	String
time	java.sql.Time
timestamp	java.sql.Timestamp
void	void
yes_no	boolean

Table 5.63 hibernateTypes

Pattern type	Hibernate type
big_decimal	big_decimal
binary	binary
blob	blob
boolean	boolean
Boolean	boolean
byte	byte
calendar_date	calendar_date
calendar	calendar
character	character
clob	clob
Date	date
DateTime	timestamp
double	double
Double	double
float	float
Float	float
integer	integer
Integer	integer
long	long
Long	long
short	short
Short	short
String	string
text	text
time	time
timestamp	timestamp
yes_no	yes_no

In the pattern a map can be used by applying the MetaFactory expression language (a simple version of el). The syntax is:

${map(mapName, key)}

Example

${map(javaTypes, big_decimal)}

which returns java.math.BigDecimal
