Method Summary

IPersistentObject	create(java.lang.Class<?> typ, java.lang.String id, boolean persistent) Create an IPersistentObject.
IPersistentObject[]	executeQuery(Query qbe)
IPersistentObject	fetch(java.lang.Class<?> typ, java.lang.String id) Fetch an IPersistentObject from the storage.
void	setBinding(java.util.Map<java.lang.String,java.lang.Class<? extends IPersistentObject>> map) get an arbitrary Property from an IPersistentObject

Method Detail

fetch

IPersistentObject fetch(java.lang.Class<?> typ,
                        java.lang.String id)
                        throws ElexisCoreException

Fetch an IPersistentObject from the storage. This is a replacement for the static load(String)-Methods of earlier PersistentObject implementations

Parameters:

clazz - full qualified class name of the Object to load

id - GUID of the object to load

Returns:

the newly created Object, populated with according properties from the data storage, or null if an Object with the given id does not exist.

Throws:

ElexisCoreException - if access to the Object was not possible (e.g. due to missing class or missing access to the storage)

create

IPersistentObject create(java.lang.Class<?> typ,
                         java.lang.String id,
                         boolean persistent)
                         throws ElexisCoreException

Parameters:

clazz - full qualified class name of the Object to create

id - id of the Object to create. Can be null, then the id will be created by the framework

persistent - true if the Object should be persisted in the storage

Returns:

the newly created Object

Throws:

ElexisCoreException - if Creation wos not possible

setBinding

void setBinding(java.util.Map<java.lang.String,java.lang.Class<? extends IPersistentObject>> map)

get an arbitrary Property from an IPersistentObject

Parameters:

object - IPersistentObject to query

propertyName - name of the Property to read

Throws:

ElexisStorageException - id the storage is not ready

executeQuery

IPersistentObject[] executeQuery(Query qbe)
