| Method Summary | |
| void | ensureTableExists(ClassInfo parentInfo, String attributeName, boolean create)
Ensure that the table or tables (if there are some) backing this
attribute exist. | | Map | getAttributeTypes(String attributeName)
Get the attribute types that are representing this type
in the original object. | | WhereResolver.SymbolTableEntry | getSymbolEntry(AttributeSpecifier spec, WhereResolver.SymbolTableEntry previousEntry, ClassInfo previousInfo, ReferenceTerm previousTerm)
Create the approriate symbol entry when parsing a query. | | ClassInfo | getSymbolInfo(WhereResolver.SymbolTableEntry entry, AttributeSpecifier spec)
Determine the next class info after the given specifier. | | boolean | hasChanged(ClassInfo info, Object obj, String attributeName, Map dbAttributes)
Determine whether the two values differ. | | void | postSave(Object value)
Called when all save operations have completed, and all dependent
objects were saved. | | Object | save(ClassInfo classInfo, Object current, String attributeName, Transaction transaction, Long currentSerial, Object oldValue, Object newValue, Set waitingObjects, List events, Map changedAttributes, Map dbAttributes)
Save the changes occured.
Parameters:
classInfo - The class info of the parent object.
Parameters:
current - The parent object.
Parameters:
attributeName - The name of the attribute about to save.
Parameters:
transaction - The transaction the saves must occur in.
Parameters:
currentSerial - The serial id the current saved are in.
Parameters:
oldValue - The old value as known by the object tracker.
Parameters:
newValue - The new value.
Parameters:
waitingObjects - List of object on which this operation depends on.This is writable.
Parameters:
events - The events the type save generated.
Parameters:
changedAttributes - The attributes need to be updated in thedatabase.
Parameters:
dbAttributes - The database attributes.
Parameters:
updatedAttributes - The attributes that need to be updatedin the object tracker. | | Object | unmarshallType(ClassInfo classInfo, Object obj, String attributeName, Map marshalledValues, TimeControl timeControl)
Get the umarshalled instance. |
| ensureTableExists | | void ensureTableExists(ClassInfo parentInfo, String attributeName, boolean create)(Code) | | Ensure that the table or tables (if there are some) backing this
attribute exist.
Parameters:
parentInfo - The ClassInfo of the container class.
Parameters:
attributeName - The attribute name of the handled attribute.
Parameters:
create - Whether to physically create the tables or not. |
| getAttributeTypes | | Map getAttributeTypes(String attributeName)(Code) | | Get the attribute types that are representing this type
in the original object.
|
| postSave | | void postSave(Object value)(Code) | | Called when all save operations have completed, and all dependent
objects were saved.
|
| save | | Object save(ClassInfo classInfo, Object current, String attributeName, Transaction transaction, Long currentSerial, Object oldValue, Object newValue, Set waitingObjects, List events, Map changedAttributes, Map dbAttributes)(Code) | | Save the changes occured.
