Interface SiteTreeNode

All Known Implementing Classes:

SiteTreeNodeImpl

public interface SiteTreeNode

This interface is a wrapper around the more general w3c.Node which hides some details which are irrelevant for site tree nodes. It basically delegates everything to the Node.

Method Detail

getParentId

java.lang.String getParentId()

Get the parent-id of this node.

Returns:

the parent-id.

getParent

SiteTreeNode getParent()

Returns the parent node of this node.

Returns:

A sitetree node.

getParent

SiteTreeNode getParent(java.lang.String language)

Returns the parent node of this node or null if the parent has no label for the given language.

Parameters:

language - A language string.

Returns:

A sitetree node.

getAbsoluteId

java.lang.String getAbsoluteId()

Get the absolute id of this node.

Returns:

the absolute id.

getAbsoluteParentId

java.lang.String getAbsoluteParentId()

Get the absolute parent-id of this node.

Returns:

the absolute parent-id.

getId

java.lang.String getId()

Get the id of this node.

Returns:

the node id.

getLabels

Label[] getLabels()

Get all labels for this node (independent of their language attribute).

Returns:

an Array of labels.

getLabel

Label getLabel(java.lang.String xmlLanguage)

Get the label for a specific language.

Parameters:
