Method Detail

cutStringToByteLength

public static java.lang.String cutStringToByteLength(java.lang.String str,
                                                     int max)

truncates a string to a certain byte length. is assumes that each non-ascii character takes 2 bytes space which is considered for how much has to be cut off.

Parameters:

max - the allowed max byte length

preloadLocalizedProperties

public static void preloadLocalizedProperties(java.util.Set<PK> langPKs,
                                              java.util.Collection<LocalizableItemRemote> _items)

createProperties

public static EJBPropertyRowCache createProperties(TypeInfoMap infoMap,
                                                   PK itemPK,
                                                   PK typePK,
                                                   PK langPK,
                                                   long timestamp)

getProperties

public static EJBPropertyRowCache getProperties(TypeInfoMap infoMap,
                                                PK itemPK,
                                                PK typePK,
                                                PK langPK,
                                                long timestamp)

reads all unlocalized or localized properties of one language for a specified item in a property cache object.

Parameters:

itemPK - the PK of the item these properties belong to

typePK - the item type - this is needed to get the correct TypeInfoMap

langPK - the language PK of the properties, or null for unlocalized properties

timestamp - the property timestamp of the item - the propert cache uses this to check later if it is uptodate

updatePropertyTypePKs

public static void updatePropertyTypePKs(TypeInfoMap infoMap,
                                         PK itemPK,
                                         PK newTypePK)

changes all property data rows of one item to the new type pk. this will not invalidate any of its property caches - so make sure they are reloaded when the type has changed

writeProperties

public static void writeProperties(EJBPropertyRowCache prc,
                                   PK itemPK,
                                   PK typePK,
                                   TypeInfoMap infoMap,
                                   boolean localized)

saves all changed properties of one property cache.

Parameters:

prc - the (modified) property cache

infoMap - provides the correct columns and value classes for these properties

getChangeData

public static java.util.List<java.lang.Object>[] getChangeData(java.sql.Connection con,
                                                               TypeInfoMap infoMap,
                                                               EJBPropertyRowCache prc,
                                                               boolean localized)
                                                        throws java.sql.SQLException

for a modified property cache this puts together the list of columns, values and value classes. use these to build and fill you SQL statements.

Parameters:

infoMap - provides column names and value classes for properties

prc - the modified property cache

localized - tells if localized or unlocalized properties should be written - used for checking correctness of data

con - the database connection

Returns:

( [column-name, value, ValueWriter ] )

Throws:

java.sql.SQLException

removeAllPropertyData

public static void removeAllPropertyData(PK itemPK,
                                         PK typePK)

removes all property rows for a item.

Parameters:

itemPK - the item to remove properties for

typePK - used for getting the correct TypeInfoMap

readPropertyRow

public static EJBPropertyRowCache readPropertyRow(java.sql.ResultSet rs,
                                                  PK itemPK,
                                                  PK itemTypePK,
                                                  PK langPK,
                                                  long timestamp,
                                                  TypeInfoMap infoMap)
                                           throws java.sql.SQLException

Throws:

java.sql.SQLException
