Class MapFacade

java.lang.Object

org.openxava.model.MapFacade

public class MapFacade
extends java.lang.Object

Allows manage model objects in Map format.

It's used in generic OpenXava action to make CRUD operations, but if it's convenient for you, you can use directly.

A principle a good design is use maps for generic or automatic things, but in all other cases the use of the model objects directly is better, because the compiler do a good work for us, we can use method calls, etc.

We use the EJB exceptions (CreateException, FinderException, RemoveException, etc) with the typical semantic associated to each. Although the implementation does not use EJB.
We use RemoteException to indicate a system error. Although the implementation is local.
Since version 3.0 MapFacade uses runtime exception for system errors, before (in v2.x) it used RemoteException.
The first parameter of each method is modelName, this is a name of a OpenXava component (Customer, Invoice, etc) or a qualified aggregate (Invoice.InvoiceDetail for example).

Transactional behaviour

MapFacade has transactional behaviour inside your action or test (since 2.2.5). That is, you can write the next code inside an action or test:

 public void execute() throws Exception {
                ...
                MapFacade.create("Customer", customerValue);
                MapFacade.create("Invoice", invoiceValue);
                ... 
 }
 

If Invoice creation fails, the Customer will not be saved; moreover if any other exception is thrown by other sentence of the action. Both Customer and Invoice data will not be saved.
The data is flushed in each MapFacade call, but not committed.
This behavior can be modified for your application with the next property in xava.properties file:

 mapFacadeAutoCommit=true
 

If you mapFacadeAutoCommit=true or mapFacadeAsEJB=true and you execute the above code, if the creation of Invoice fails, the Customer is already saved and committed and it will not be removed.

When autocommit is not used (the default) you can do a commit programatically, using the @{link #commit()} method. In this way:

 public void execute() throws Exception {
                ...
                MapFacade.create("Customer", customerValue);
                MapFacade.commit();
                MapFacade.create("Invoice", invoiceValue);
                ... 
 }

getValues

                                      SystemException

Obtain the specified values from entity/aggregate from a map with primary key values.

The memberNames parameter is a map to use a treelike structure.
The property names are in key part. If it's a simple property the value is null, otherwise it has a map with the same structure.
For example, if we have a Customer that references to a Seller, we can send a map with the next values:

 
 { "number", null }
 { "name", null }
 { "seller", { {"number", null}, {"name", null} } }
 

Parameters:

modelName - OpenXava model name. Not null.

keyValues - Key values of object to find. Not null. By value semantics.

memberNames - Member names to obtain its values. Not null. By value semantics.

Returns:

Map with entity values. Not null.

Throws:

javax.ejb.ObjectNotFoundException - If object with this key does not exist

javax.ejb.FinderException - Logic problem on find.

XavaException - Any problem related to OpenXava. Rollback transaction.

SystemException - System problem. Rollback transaction.

                                                   XavaException,
                                                   SystemException

Obtain the specified values from entity/aggregate searching it by any property.

The memberNames parameter is a map to use a treelike structure.
The property names are in key part. If it's a simple property the value is null, otherwise it has a map with the same structure.
For example, if we have a Customer that references to a Seller, we can send a map with the next values:

 
 { "number", null }
 { "name", null }
 { "seller", { {"number", null}, {"name", null} } }
 

The searchingValues parameters are the values used to search. For example, if you can search by name and surname you can send to searchingValues a map with the next values:

 
 { "name", "JUAN" }
 { "surname", "PEREZ" }
 

In this case it returns the map with the value of the first "JUAN PEREZ" of database.

If you use:

 { "name", "J" }
 

Then it returns the values for the first object of which name starts with 'J'.

If you use:

 { "description", "%BIG" }
 

Then it returns the values for the first object of which description contains "BIG".

Parameters:

modelName - OpenXava model name. Not null.

searchingValues - Values used for search the object. Not null. By value semantics.

memberNames - Member names to obtain its values. Not null. By value semantics.

Returns:

Obtain the values of the entity/aggregate from the own entity.

The memberNames parameter is a map to use a treelike structure.
The property names are in key part. If it's a simple property the value is null, otherwise it has a map with the same structure.

 { "number", null }
 { "name", null }
 { "seller", { {"number", null}, {"name", null} } }

Removes an elemente from a collection.

If it's a aggregate remove the aggregate, and if it's a entity reference make the left to point to the parent object, hence left the collection.
Does not delete aggregates directly, but with this method, because thus the needed logic for remove a element from a collection is executed.

Parameters:

modelName - OpenXava model name. Not null.

keyValues - Key value of the container of the collection. Not null. By value semantics.

collectionName - Collection name of the container collection of element to remove. Not null.

collectionElementKeyValues - Key value of element to remove. Not null. By value semantics.

Throws:

javax.ejb.FinderException - Logic problem on find.

ValidationException - Data validation problems.

javax.ejb.RemoveException - Logic problem on remove.

keyValues - Key value of the container of the collection. Not null. By value semantics.

collectionName - Collection name of the container collection of element to add. Not null.
