org.itsnat.core.domutil .ElementTreeNode

All known Subclasses:   org.itsnat.impl.core.domutil .ElementTreeNodeImpl,
ElementTreeNode
public interface ElementTreeNode extends ElementGroup(Code)
Represents a pattern based DOM tree node. A tree node contains (may contain) a handle, an icon and a label elements (these three are the node "content"), and may have child nodes. The tree node structure is used as pattern to create child tree nodes (by using a deep clone), so all child tree nodes have the same structure (same as the pattern), unless there is one child node in markup.
This interface supports "out the box" the typical DOM tree node structure with handle, icon and label elements:

<parent> <content><handle/><icon/><label>markup of label</label></content> <children> ...child tree nodes go here </children> </parent>

The label element is normally used to render below the value associated to node. The method ElementTreeNode.setValue(Object) is used to render this value, the structure and renderer objects are used to customize how and where this value is saved in the tree node beyond the default cases.

A pattern based DOM tree node ever works in "master" mode, see ElementListFree.isMaster .
