Direct Known Subclasses:

ProxyTreeMapCT

public class ProxyTreeMap

extends java.util.TreeMap

implements ProxyMap

Extension of the TreeMap type that dirties the persistent/transactional field it is assigned to on modification. The need to dirty the field on any modification mandates that this class must override all mutator methods of the base type. This may lead to multiple calls to the PersistenceCapable.jdoMakeDirty(java.lang.String) for one state change if one mutator method of the base type calls another.

Constructor Detail

ProxyTreeMap

public ProxyTreeMap()

Template constructor.

ProxyTreeMap

public ProxyTreeMap(java.util.Comparator comp,
                    java.lang.Class keyType,
                    java.lang.Class valueType)

Constructor.

Parameters:

comp - The comparator that should be used to determine the sort order of the elements in this map.

keyType - All keys in this map must be instances of this type.

valueType - All values in this map must be instances of this type.

Method Detail

newInstance

public com.solarmetric.rd.kodo.util.ProxyMap newInstance(java.lang.Class keyType,
                                                         java.lang.Class valueType,
                                                         java.util.Map contents,
                                                         java.util.Comparator compare)

Description copied from interface: ProxyMap

This method should return a new proxy of the same concrete type as the implementing class. Used by the ProxyManager factories: one template instance of each type is created for the purpose of producing new instances via this method. Overcomes the performance penalties of reflection.

Specified by:

newInstance in interface ProxyMap

getCopy

public java.util.Map getCopy(java.util.Map orig)

Description copied from interface: ProxyMap

This method should return a copy of the given map; the copy should be of the same class as the superclass of this collection.

Specified by:

getCopy in interface ProxyMap

getComparator

public java.util.Comparator getComparator()

Description copied from interface: ProxyMap

Return the comparator used in this map, or null if it is unordered or uses natural ordering.

Specified by:

getComparator in interface ProxyMap

setOwner

public void setOwner(java.lang.Object pc,
                     java.lang.String fieldName)

Description copied from interface: Proxy

Set the owning JDO instance of the proxy and the name of the field it is assigned to. Set to null to indicate that the proxy is no longer managed.

Specified by:

setOwner in interface Proxy

getOwner

public java.lang.Object getOwner()

Description copied from interface: Proxy

Return the owning object.

Specified by:

getOwner in interface Proxy

getOwnerFieldName

public java.lang.String getOwnerFieldName()

Description copied from interface: Proxy

Return the owning field name.

Specified by:

getOwnerFieldName in interface Proxy

isOwner

public boolean isOwner(java.lang.Object pc,
                       java.lang.String fieldName)

Description copied from interface: Proxy
