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)

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
