public abstract class ExpanderBasedStructureBean extends AbstractStructureBean implements ExpanderChain.Default
StructureBeans that uses
Expanders to expand and collapse nodes. You can add multiple
expanders to create a chain of expanders. The
default expander is however always provided by the StructureBean
implementation class. For example, this implementation retrieves the default
Expander from the current View. Subclasses are allowed to
change what the default expander will be by overriding the
getDefaultExpander() method.
ExpanderBasedStructureBean s = ... assert s.getExpander() == s.getDefaultExpander(); Expander a = ... s.getExpanderChain().add(a); assert a == s.getExpander(); assert s.getDefaultExpander() == s.getExpanderChain().getNext(a); Expander b = ... s.getExpanderChain().add(b); assert b == s.getExpander(); assert a == s.getExpanderChain().getNext(b); assert s.getDefaultExpander() == s.getExpanderChain().getNext(a); Expander[] x = s.getExpanderChain().getExpanders(); assert x.length == 2; assert x[0] == b; assert x[1] == a;

Default constructor...
|
| Modifier and Type | Method and Description |
|---|---|
protected Expander.ExpandCtx |
createExpandCtx()
Subclasses can return a different
context object, or
use the default returned by this method. |
protected StructureBeanNode |
createRootNode(java.lang.String rootObjectId)
Creates a root node with the specified object ID.
|
protected StructureBeanNode |
createStructureNode(java.lang.String relationshipId,
java.lang.String objectId,
boolean from)
Creates a node with the specified relationship ID, object ID and
direction.
|
protected void |
doCollapseNode(StructureBeanNode node)
Delegates the collapse to the
Expander. |
protected void |
doExpandNode(StructureBeanNode node,
int levels)
Delegates the expand to the
expander. |
Expander |
getDefaultExpander()
This method returns the default expander.
|
Expander |
getExpander()
Returns the
Expander currently used by this StructureBean |
ExpanderChain |
getExpanderChain()
Returns the chain of expanders.
|
protected long |
getNextNodeId()
Returns the ID for the next node.
|
boolean |
isFiltersCombinable()
This method delegates to the
expander to get whether or
not the filters are combinable. |
boolean |
isFullExpandSupported()
Delegates to the expander.
|
boolean |
isMultiLevelExpandSupported()
Delegates to the expander.
|
boolean |
isVisualsChangeable()
Overloaded in order to allow the expander to decide this.
|
protected void |
onClone(TableBean<StructureBeanNode> c)
Create a deep copy of this object.
|
protected void |
onNavigate(TableBean<? extends TableData> table,
java.lang.String objectId)
Initializes the new table/structure.
|
protected Expander |
verifyExpander()
Returns the current expander.
