Method Detail

frapBOFromCache

public static <V extends BO> V frapBOFromCache(BOLoaderI bol,
                                               V bo)

Import a sub graph connected to the bo into this BOLoaderI, deep cloning the objects if necessary.

Returns:

a BO which has the bol as it's BOLoaderI, and all relations integrated into the current BOLoaderI object graph

queryBO

public static java.util.List queryBO(BOLoaderI bol,
                                     groovy.lang.GString query)

Enables the use of GString as query strings using parameters behind the scene, e.g.

 def name="Admin"
 tx.queryBO("Benutzer a WHERE Name=${->name}")
 

will execute the query "Benutzer a WHERE Name=$1" with parameterlist ['Admin']. Please mind that the parameters need to be written in closure syntax, which is either ${->name} or ${sw->sw.append('bla')}

queryBO

public static <V extends BO> java.util.List<V> queryBO(BOLoaderI bol,
                                                       java.lang.Class<V> entityClass,
                                                       groovy.lang.GString query)

query

public static de.ipcon.db.core.QueryResultsI query(BOLoaderI bol,
                                                   groovy.lang.GString query)

Enables the use of GString as query strings, queryBO(BOLoaderI,GString)

prepareQuery

public static BatchedBackendRequestI prepareQuery(BOLoaderI bol,
                                                  groovy.lang.GString query)

Enables the use of GString to prepare queries, queryBO(BOLoaderI,GString)
