Field Detail
LOCALISER
final protected static Localiser LOCALISER(Code)



allowNulls
protected transient boolean allowNulls(Code)



delegate
protected java.util.Properties delegate(Code)
The internal "delegate".



fieldName
protected transient String fieldName(Code)



fieldNumber
protected transient int fieldNumber(Code)



owner
protected transient Object owner(Code)



ownerSM
protected transient StateManager ownerSM(Code)




Constructor Detail
Properties
public Properties(StateManager ownerSM, String fieldName)(Code)
Constructor
Parameters:
  ownerSM - the owner of this Map
Parameters:
  fieldName - the declared field name




Method Detail
attachCopy
public void attachCopy(Object value)(Code)
Method to return an attached copy of the passed (detached) value. The returned attached copy is a SCO wrapper. Goes through the existing keys/values in the store for this owner field and removes ones no longer present, and adds new keys/values. All keys/values in the (detached) value are attached.
Parameters:
  value - The new (map) value



clear
public synchronized void clear()(Code)
Method to clear the Hashtable



clone
public Object clone()(Code)
Creates and returns a copy of this object.

Mutable second-class Objects are required to provide a public clone method in order to allow for copying PersistenceCapable objects. In contrast to Object.clone(), this method must not throw a CloneNotSupportedException. The cloned object




containsKey
public boolean containsKey(Object key)(Code)
Method to return if the map contains this key
Parameters:
  key - The key Whether it is contained



containsValue
public boolean containsValue(Object value)(Code)
Method to return if the map contains this value.
Parameters:
  value - The value Whether it is contained



detachCopy
public Object detachCopy(FetchPlanState state)(Code)
Method to return a detached copy of the container. Recurse sthrough the keys/values so that they are likewise detached.
Parameters:
  state - State for detachment process The detached container



entrySet
public java.util.Set entrySet()(Code)
Accessor for the set of entries in the Map. Set of entries



equals
public synchronized boolean equals(Object o)(Code)
Method to check the equality of this map, and another.
Parameters:
  o - The map to compare against. Whether they are equal.



flush
public void flush()(Code)
Method to flush the changes to the datastore when operating in queued mode. Does nothing in "direct" mode.



get
public Object get(Object key)(Code)
Accessor for the value stored against a key.

Accessor for the owner that this Hashtable relates to. The owner



getValue
public Object getValue()(Code)
Accessor for the unwrapped value that we are wrapping. The unwrapped value



hashCode
public synchronized int hashCode()(Code)
Method to generate a hashcode for this Map. The hashcode.



initialise
public void initialise(Object o, boolean forInsert, boolean forUpdate)(Code)
Method to initialise the SCO from an existing value.
Parameters:
  o - Object to set value using.
Parameters:
  forInsert - Whether the object needs inserting in the datastore with this value
Parameters:
  forUpdate - Whether to update the datastore with this value



initialise
public void initialise()(Code)
Method to initialise the SCO for use.



isEmpty
public boolean isEmpty()(Code)
Method to return if the Map is empty. Whether it is empty.



keySet
public java.util.Set keySet()(Code)
Accessor for the set of keys in the Map. Set of keys.



load
public void load()(Code)
Method to effect the load of the data in the SCO. Used when the SCO supports lazy-loading to tell it to load all now.



makeDirty
public void makeDirty()(Code)
Utility to mark the object as dirty



put
public Object put(Object key, Object value)(Code)
Method to add a value against a key to the Hashtable
Parameters:
  key - The key
Parameters:
  value - The value The previous value for the specified key.



putAll
public void putAll(java.util.Map m)(Code)
Method to add the specified Map's values under their keys here.
Parameters:
  m - The map



remove
public Object remove(Object key)(Code)
Method to remove the value for a key from the Hashtable
Parameters:
  key - The key to remove The value that was removed from this key.



size
public int size()(Code)
Method to return the size of the Map. The size



unsetOwner
public synchronized void unsetOwner()(Code)
Method to unset the owner and field details.



updateEmbeddedKey
public void updateEmbeddedKey(Object key, int fieldNumber, Object newValue)(Code)
Method to update an embedded key in this map.
Parameters:
  key - The key
Parameters:
  fieldNumber - Number of field in the key
Parameters:
  newValue - New value for this field



updateEmbeddedValue
public void updateEmbeddedValue(Object value, int fieldNumber, Object newValue)(Code)
Method to update an embedded value in this map.
Parameters:
  value - The value
Parameters:
  fieldNumber - Number of field in the value
Parameters:
  newValue - New value for this field



values
public Collection values()(Code)
Accessor for the set of values in the Map. Set of values.



writeReplace
protected Object writeReplace() throws ObjectStreamException(Code)
The writeReplace method is called when ObjectOutputStream is preparing to write the object to the stream. The ObjectOutputStream checks whether the class defines the writeReplace method. If the method is defined, the writeReplace method is called to allow the object to designate its replacement in the stream. The object returned should be either of the same type as the object passed in or an object that when read and resolved will result in an object of a type that is compatible with all references to the object. the replaced object
throws:
  ObjectStreamException -
