Constructor Detail

MappingConnectionExecutor

public MappingConnectionExecutor(MappingConnectionManager manager,
                                 MappingConnectionManager.MappingConnectionDescription[] objectDescriptions)

Constructor.

Parameters:

manager - is the ToolManager.

objectDescriptions - are the object descriptions.

Method Detail

getResults

public MappingConnection[] getResults()

Get the result.

Returns:

the looked-up or read cached instances.

create

public java.lang.Object[] create(ICacheDescription[] objectDescriptions)
                          throws ManifoldCFException

Create a set of new objects to operate on and cache. This method is called only if the specified object(s) are NOT available in the cache. The specified objects should be created and returned; if they are not created, it means that the execution cannot proceed, and the execute() method will not be called.

Parameters:

objectDescriptions - is the set of unique identifier of the object.

Returns:

the newly created objects to cache, or null, if any object cannot be created. The order of the returned objects must correspond to the order of the object descriptinos.

Throws:

ManifoldCFException

exists

public void exists(ICacheDescription objectDescription,
                   java.lang.Object cachedObject)
            throws ManifoldCFException

Notify the implementing class of the existence of a cached version of the object. The object is passed to this method so that the execute() method below will have it available to operate on. This method is also called for all objects that are freshly created as well.

Parameters:

objectDescription - is the unique identifier of the object.

cachedObject - is the cached object.

Throws:

ManifoldCFException

execute

public void execute()
             throws ManifoldCFException

Perform the desired operation. This method is called after either createGetObject() or exists() is called for every requested object.

Throws:

ManifoldCFException
