Date	copyDate(Date orig) Return a copy of the given date with the same information.
Map	copyMap(Map orig) Return a new map of the same type as the given one with a copy of all contained key/value pairs.
boolean	getAssertAllowedType() Whether to perform runtime checks to ensure that all elements added to collection and map proxies are the proper element/key/value type as defined by the JDO metadata.
boolean	getTrackChanges() Whether proxies produced by this factory will use ChangeTrackers to try to cut down on data store operations at the cost of some extra bookkeeping overhead.

Method Detail

getTrackChanges

public boolean getTrackChanges()

Whether proxies produced by this factory will use ChangeTrackers to try to cut down on data store operations at the cost of some extra bookkeeping overhead. Defaults to true.

setTrackChanges

public void setTrackChanges(boolean track)

Whether proxies produced by this factory will use ChangeTrackers to try to cut down on data store operations at the cost of some extra bookkeeping overhead. Defaults to true.

getAssertAllowedType

public boolean getAssertAllowedType()

Whether to perform runtime checks to ensure that all elements added to collection and map proxies are the proper element/key/value type as defined by the JDO metadata. Defaults to false.

setAssertAllowedType

public void setAssertAllowedType(boolean assertType)

Whether to perform runtime checks to ensure that all elements added to collection and map proxies are the proper element/key/value type as defined by the JDO metadata. Defaults to false.

copyDate

public Date copyDate(Date orig)

Description copied from interface: ProxyManager

Return a copy of the given date with the same information.

Specified by:

copyDate in interface ProxyManager

copyCollection

public Collection copyCollection(Collection orig)

Description copied from interface: ProxyManager

Return a new collection of the same type as the given one with a copy of all contained elements. If the given owner is non-null, the returned value should be a proxy for the given owner, otherwise it should not be a proxy.

Specified by:

copyCollection in interface ProxyManager

copyMap

public Map copyMap(Map orig)

Description copied from interface: ProxyManager

Return a new map of the same type as the given one with a copy of all contained key/value pairs. If the given owner is non-null, the returned value should be a proxy for the given owner, otherwise it should not be a proxy.

Specified by:

copyMap in interface ProxyManager

copyArray

public Object copyArray(Object orig)

Description copied from interface: ProxyManager

Return a new array of the same component type as the given array and containing the same elements. Works for both primitive and object array types.

Specified by:

copyArray in interface ProxyManager

copyCustom

public Object copyCustom(Object orig)

Description copied from interface: ProxyManager

Return a copy of the given object with the same information. If this manager cannot proxy the given type, return null. If the given owner is non-null, the returned value should be a proxy for the given owner, otherwise it should not be a proxy.

Specified by:

copyCustom in interface ProxyManager

newDateProxy

public ProxyDate newDateProxy()

Description copied from interface: ProxyManager

Return a new date proxy.

Specified by:

newDateProxy in interface ProxyManager

newCollectionProxy

public ProxyCollection newCollectionProxy(Class type,
                                          Class elementType,
                                          Comparator compare)

Description copied from interface: ProxyManager

Return a proxy for the given collection type. The returned collection will allow only addition of elements assignable from the given element type and will use the given comparator, if it is not null.

Specified by:

newCollectionProxy in interface ProxyManager

newMapProxy

public ProxyMap newMapProxy(Class type,
                            Class keyType,
                            Class valueType,
                            Comparator compare)

Description copied from interface: ProxyManager

Return a proxy for the given map type. The returned map will allow only addition of keys/values assignable from the given keyType/valueType, and will use the given comparator, if it is not null.

Specified by:

newMapProxy in interface ProxyManager

newCustomProxy

public Proxy newCustomProxy(Class type)

newCustomProxy

public Proxy newCustomProxy(Object obj)

Description copied from interface: ProxyManager

Return a proxy for the given object, or null if this manager cannot proxy the object.

Specified by:

newCustomProxy in interface ProxyManager
