Interface WrapperFactory

All Known Implementing Classes:

AbstractWrapperFactory, GenericWrapperFactory, JSAccessRequestBatchWrapperFactory, JSAttributeValueWrapperFactory, JSCollectionWrapperFactory, JSDirectoryObjectWrapperFactory, JSDNWrapperFactory, JSIRuleResultWrapperFactory, JSMapWrapperFactory, JSPackagedApprovalDocumentWrapperFactory, JSPackagedApprovalItemWrapperFactory, JSRAAttributeWrapperFactory, JSRAObjectWrapperFactory

public interface WrapperFactory

A class that implements WrapperFactory knows how to wrap a specific type of Object or a set of objects. Some scripting engines require a specific wrapper just for that engine. In those cases the WrapperFactory implementation must be aware of each scripting language supported.

Since:

ITIM 5.0

Field Summary

static java.lang.String	FESI_LANG Constant WrapperFactory classes can use to check for use of the FESI engine.
static java.lang.String	IBMJS_LANG Constant WrapperFactory classes can use to check for use of the IBMJS engine.

Method Summary

java.lang.Object	getObjectToStore(java.lang.Object obj) Get the object that should be returned on a lookup call on ObjectWrapperManager.
ObjectWrapper	wrap(java.lang.Object obj, java.lang.String lang, java.lang.Object param) Correctly wrap the given object to use in the scripting environment.

Method Detail

wrap

ObjectWrapper wrap(java.lang.Object obj,
                   java.lang.String lang,
                   java.lang.Object param)

Correctly wrap the given object to use in the scripting environment. If a wrapper that a WrapperFactory creates does not need any special context information, it is safe to ignore lang and param.

Parameters:

obj - The Object to wrap.

lang - The scripting language we are using. This is used to choose a specific wrapper if the wrapper must vary depending on scripting language.

param - Some wrapper classes need parameters to correctly wrap objects. param is how this information is passed. param can be null if no extra information is necessary.

Returns:

null - if (obj == null)
null - if param is not sufficient to wrap the object for the given language.
Wrapped object - else.

getObjectToStore

java.lang.Object getObjectToStore(java.lang.Object obj)

Get the object that should be returned on a lookup call on ObjectWrapperManager. This method exists so that if a different object should be returned than is passed in. This is the case if a DirectoryObjectEntity is wrapped, but a DirectoryObject should be returned. In most cases obj will be returned.

Parameters:

obj - The same object that was passed wrap.

Returns:

The object to store in ObjectWrapperManagers lookup map.
