Method Detail

getWCID

static String getWCID(Persistable object)
               throws WTException

Compute the string key for the object (EPMDocument, EPMDocumentMaster) EPMDocument and EPMDocumentMaster use their referenceString.

Throws:

WTException

getObjectFromTable

static Object getObjectFromTable(Hashtable objects,
                                 Object object)
                          throws WTException

Get the canonical copy of an object from the cache.

Throws:

WTException

getLinkFromTable

static com.objectspace.jgl.Pair getLinkFromTable(Hashtable objects,
                                                 com.objectspace.jgl.Pair pair)
                                          throws WTException

Get the canonical copy of an EPMMemberLink from the cache. If the object already exists in the table, the cached copy is returned. If the object does not already exist in the table, a Pair containing the EPMMemberLink and the link target is created, and inserted in the table, and returned.

Throws:

WTException

getMasterFromTable

static EPMDocumentMaster getMasterFromTable(Hashtable objects,
                                            EPMDocumentMaster mastered)
                                     throws WTException

Get the canonical copy of an EPMDocumentMaster from the cache. If the object already exists in the table, the cached copy is returned. If the object does not already exist in the table, an EPMRecursiveResultSet containing the EPMDocumentMaster is created, and inserted in the table, and the original object is returned.

Throws:

WTException

getDocumentFromTable

static EPMDocument getDocumentFromTable(Hashtable objects,
                                        EPMDocument iterated)
                                 throws WTException

Get the canonical copy of an EPMDocument from the cache. If the object already exists in the table, the cached copy is returned. If the object does not already exist in the table, an EPMRecursiveResultSet containing the EPMDocument is created, and inserted in the table, and the original object is returned. If not already present, a cache entry for the EPMDocumentMaster is created.

Throws:

WTException

navigateDownRecursive

static EPMRecursiveResultSet navigateDownRecursive(EPMDocument doc,
                                                   QuerySpec querySpec,
                                                   boolean onlyOther,
                                                   ConfigSpec spec,
                                                   Class linkClass,
                                                   String roleName,
                                                   int depth,
                                                   Hashtable objects)
                                            throws WTException,
                                                   WTPropertyVetoException
