MetafacadeFactory when constructing or retrieving metafacade
instances. If the cache constains the metafacade it should not be constructed again.

| Method Summary | |
| final public void | add(Object mappingObject, MetafacadeBase metafacade)
Adds the metafacade to the cache according to first mappingObject, second the
metafacade, and finally by the current namespace. | | final public void | clear()
| | final public MetafacadeBase | get(Object mappingObject, Class metafacadeClass)
Returns the metafacade from the metafacade cache. | | public static MetafacadeCache | newInstance()
Constructs a new instance of this class. | | final public void | setNamespace(String namespace)
Sets the namespace to which the cache currently applies. | | public String | toString()
|
| add | | final public void add(Object mappingObject, MetafacadeBase metafacade)(Code) | | Adds the metafacade to the cache according to first mappingObject, second the
metafacade, and finally by the current namespace.
Parameters:
mappingObject - the mappingObject for which to cache the metafacade.
Parameters:
metafacade - the metafacade to cache. |
| clear | | final public void clear()(Code) | | Clears the cache of any metafacades
|
| get | | final public MetafacadeBase get(Object mappingObject, Class metafacadeClass)(Code) | |
Returns the metafacade from the metafacade cache. The Metafacades are cached first by according to its
mappingObject, next the metafacadeClass, and finally by the current namespace.
Metafacades must be cached in order to keep track of the state of its validation. If we keep creating a new one
each time, we can never tell whether or not a metafacade has been previously validated. Not to mention tremendous
performance gains.
Parameters:
mappingObject - the object to which the mapping applies
Parameters:
metafacadeClass - the class of the metafacade. MetafacadeBase stored in the cache. |
| newInstance | | public static MetafacadeCache newInstance()(Code) | | Constructs a new instance of this class.
the new instance |
| setNamespace | | final public void setNamespace(String namespace)(Code) | | Sets the namespace to which the cache currently applies.
Parameters:
namespace - the current namespace. |
