Interface CopyBehaviourCallback

All Known Implementing Classes:

Nested Class Summary

Nested Classes

Modifier and Type	Interface	Description
static enum	CopyBehaviourCallback.AssocCopySourceAction	Description of how the copy process should handle multiplicity of peer associations at the source end of the association. The order of this enum denotes the priority when mixing behaviour as well; that is to say that a 'ignore' behaviour will occur even if an 'copy' is also provided by the registered behaviour callbacks.
static enum	CopyBehaviourCallback.AssocCopyTargetAction	Description of how the copy process should handle multiplicity of peer associations at the target end of the association. The order of this enum denotes the priority when mixing behaviour as well; that is to say that a 'ignore' behaviour will occur even if an 'copy' is also provided by the registered behaviour callbacks.
static enum	CopyBehaviourCallback.ChildAssocCopyAction	Description of how the copy process should traverse a child association.
static enum	CopyBehaviourCallback.ChildAssocRecurseAction	Description of how the copy process should behave when copying an association.
static final class	CopyBehaviourCallback.CopyAssociationDetails	A simple bean class to convey information to the callback methods dealing with copying of associations.
static final class	CopyBehaviourCallback.CopyChildAssociationDetails	A simple bean class to convey information to the callback methods dealing with copying of child associations.

Method Summary

Modifier and Type	Method	Description
Pair<CopyBehaviourCallback.AssocCopySourceAction,CopyBehaviourCallback.AssocCopyTargetAction>	getAssociationCopyAction(QName classQName, CopyDetails copyDetails, CopyBehaviourCallback.CopyAssociationDetails assocCopyDetails)	Determine the copy behaviour associated with a given peer association.
CopyBehaviourCallback.ChildAssocCopyAction	getChildAssociationCopyAction(QName classQName, CopyDetails copyDetails, CopyBehaviourCallback.CopyChildAssociationDetails childAssocCopyDetails)	Determine if a copy should copy the child, the association only or do nothing with the given association.
CopyBehaviourCallback.ChildAssocRecurseAction	getChildAssociationRecurseAction(QName classQName, CopyDetails copyDetails, CopyBehaviourCallback.CopyChildAssociationDetails childAssocCopyDetails)	Once the child association copy action has been chosen, the policy callback can dictate whether or not to force further recursion.
Map<QName,Serializable>	getCopyProperties(QName classQName, CopyDetails copyDetails, Map<QName,Serializable> properties)	Modify the properties that are copied across.
boolean	getMustCopy(QName classQName, CopyDetails copyDetails)	Determine if this type or aspect must be copied.
boolean	isTopLevelCanBeRenamed(QName classQName, CopyDetails copyDetails)	Determine if this top-level node with type or aspect can be renamed during copy.

Method Details

getMustCopy

boolean getMustCopy(QName classQName,
 CopyDetails copyDetails)

Determine if this type or aspect must be copied. If the callback is for a type (not aspect) then this determines if the node is copied at all. If the callback is for an aspect, then this determines if the aspect is copied.

Parameters:

classQName - the name of the class that this is being invoked for

copyDetails - the source node's copy details for quick reference

Returns:

true if the type or aspect that this behaviour represents must be copied.

isTopLevelCanBeRenamed

boolean isTopLevelCanBeRenamed(QName classQName,
 CopyDetails copyDetails)

Determine if this top-level node with type or aspect can be renamed during copy.

Parameters:

classQName - the name of the class that this is being invoked for

copyDetails - the source node's copy details for quick reference

Returns:

true if the top-level node with type or aspect can be renamed during copy.

getAssociationCopyAction

Pair<CopyBehaviourCallback.AssocCopySourceAction,CopyBehaviourCallback.AssocCopyTargetAction> getAssociationCopyAction(QName classQName,
 CopyDetails copyDetails,
 CopyBehaviourCallback.CopyAssociationDetails assocCopyDetails)

Determine the copy behaviour associated with a given peer association.

Parameters:

classQName - the name of the class that this is being invoked for

copyDetails - the source node's copy details for quick reference

assocCopyDetails - all other details relating to the association

Returns:

Returns the copy actions (source and target) to take with the given association

getChildAssociationCopyAction

CopyBehaviourCallback.ChildAssocCopyAction getChildAssociationCopyAction(QName classQName,
 CopyDetails copyDetails,
 CopyBehaviourCallback.CopyChildAssociationDetails childAssocCopyDetails)

Determine if a copy should copy the child, the association only or do nothing with the given association.

This is called regardless of whether 'cascade' copy has been selected by the client of the copy. Some type and aspect behaviour will mandate a copy of the child associations regardless of whether recursion is on.

Parameters:

classQName - the name of the class that this is being invoked for

copyDetails - the source node's copy details for quick reference

childAssocCopyDetails - all other details relating to the child association

Returns:

Returns the copy action to take with the given child association

getChildAssociationRecurseAction

CopyBehaviourCallback.ChildAssocRecurseAction getChildAssociationRecurseAction(QName classQName,
 CopyDetails copyDetails,
 CopyBehaviourCallback.CopyChildAssociationDetails childAssocCopyDetails)

Once the child association copy action has been chosen, the policy callback can dictate whether or not to force further recursion. This cannot prevent behaviour further down the hierarchy from stopping the copy.

Parameters:

classQName - the name of the class that this is being invoked for

copyDetails - the source node's copy details for quick reference

childAssocCopyDetails - all other details relating to the child association

Returns:

Returns the type of recursion to perform after having copied the child association

See Also:

• getChildAssociationCopyAction(QName, CopyDetails, CopyChildAssociationDetails)

getCopyProperties

Map<QName,Serializable> getCopyProperties(QName classQName,
 CopyDetails copyDetails,
 Map<QName,Serializable> properties)

Modify the properties that are copied across.

Parameters:

classQName - the name of the class that this is being invoked for

copyDetails - the source node's copy details for quick reference

properties - the type- or aspect-specific properties that can be copied. The map can be manipulated and returned as required.

Returns:

Returns the type or aspect properties that should be copied.
