Provides access to the tree and list model representation object of the layout of a
page.
Many of the following attributes return LayoutNode. However, LayoutContainer and LayoutControl are types of LayoutNode, and when you
iterate, you can encounter either type.
Attributes:
- children
- Returns the children of the specified node.
-
Example:
${wp.layoutModel[wp.selectionModel.selected].children[node]}
-
Parameters:
- node
- This value represents an entry in a model.
-
Returns: Children of the specified node.
- get(id)
- Gets an individual layout model.
-
Example:
${wp.layoutModel[id]}
-
Parameters:
- id
- String or Identifiable object to look up the layout objects. It must not be null.
-
Returns: LayoutNode; it can be null if not found.
- hasChildren
- Determines whether the current specified LayoutNode has associated nodes.
-
Example:
${wp.layoutModel[wp.selectionModel.selected].hasChildren[node]}
-
Parameters:
- node
- LayoutNode; node to check for child nodes.
-
Returns: Boolean; true if the layout node has children. Otherwise, it is false.
- iterator
- Iterates through layout nodes.
-
Example:
<c:forEach var="node" items="${wp.layoutModel[wp.selectionModel.selected]}">
</c:forEach>
-
Parameters: None
-
Returns: an iterator with LayoutNode objects; it is never null.
- parent
-
Access to the parent of a node.
-
Example:
${wp.layoutModel[wp.selectionModel.selected].parent[node]}
-
Parameters:
- node
- LayoutNode; the current node.
-
Returns: LayoutNode; the parent node for the node if there is a parent. Otherwise, it is
null.
- path
- Provides access to the path information for the node. The path represents the hierarchy from the
root to the give node as a list. It is like a breadcrumb.
-
Example:
${wp.layoutModel[wp.selectionModel.selected].path[node]}
-
Parameters:
- node
- LayoutNode; the current node.
-
Returns: a list of LayoutNodes representing the path from the root to a node.
- root
- Returns the root node of the layout model.
-
Example:
${wp.layoutModel[wp.selectionModel.selected].root}
-
Parameters: none
-
Returns: LayoutNode; it is never null.
