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)

..	list-table:: javaTypes
	:widths: 30 30
	:header-rows: 1

	*	- Pattern type
		- Java type
	*	- big_decimal
		- java.math.BigDecimal
	*	- binary

	*	- yes_no

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

.. code-block::

	${map(mapName, key)}

.. rubric:: Example

.. code-block::

	${map(javaTypes, big_decimal)}

which returns java.math.BigDecimal
