public class NodeReferenceAttribute

extends NodeExtendedAttribute

implements IsaNodeReferenceAttribute, HasNodeHandler, IsaNodeReferenceChildListener, IsaNodeReferenceListener

special refer attribute. * It is possible to create a NodeReferenceAttribute that links directly to a NodeReferenceId in the attribute list of another node by means of a java objects refeference. When the name of the id-tag changes in the referenced node than it will be reflected in the xml serialization of the NodeReferenceAttribute as it does pickup the new name automatically via the object reference.

Constructor Detail

NodeReferenceAttribute

                              IsaNodeReferenceId node)

NodeReferenceAttribute

public NodeReferenceAttribute(String name,
                              IsaNodeReferenceId node,
                              NodeHandler def)

Method Detail

setHandler

public void setHandler(NodeHandler handler)

you can set the NodeHandler in the attribute instance. which overrides the one from the referenced node - in other words the original node is not modified.

getHandler

public NodeHandler getHandler()

returns the NodeHandler of the node. This is per default the one from the referenced node unless it is overridden via the local {#setHandler}

Specified by:

getHandler in interface HasNodeHandler

getSimpleNode

public SimpleNode getSimpleNode()

Description copied from interface: IsaNodeReferenceAttribute

return the referenced node.

Specified by:

getSimpleNode in interface IsaNodeReferenceAttribute

getId

public String getId()

the Id of the referenced node.

Specified by:

getId in interface IsaNodeReferenceAttribute

getValue

public String getValue()

the value is the Id-number. overridde attribute.getValue() with attribute.node().getId(). That allows you to change the Id on the referenced Element-node and all ref-ids will change automatically.

Specified by:

getValue in interface Attribute

onNodeReferenceChildHasChanged

public void onNodeReferenceChildHasChanged(SimpleNode node)

per default, tell the referenced node that this attribute points to.

Specified by:

onNodeReferenceChildHasChanged in interface IsaNodeReferenceChildListener

onNodeReferenceHasChanged

public void onNodeReferenceHasChanged(SimpleNode node)

per default, tell the parenting node of this reference attribute.

Specified by:

onNodeReferenceHasChanged in interface IsaNodeReferenceListener

destroy

public void destroy()

toAttrXML

public String toAttrXML(String prefix)

Description copied from class: NodeExtendedAttribute

currently: nothing

Overrides:

toAttrXML in class NodeExtendedAttribute
