Method Detail

getErrorMessages

public String getErrorMessages()

Returns all error messages reported during the last call to isValid.

Returns:

A String containing the reported error messages (may be empty).

isValid

public boolean isValid(Node updateNode)

Checks that a kml:Update element satisfies all applicable constraints. In particular:

1. if it is not empty, the kml:targetHref element contains an absolute URI that refers to a KML or KMZ resource.
2. All KML objects that are the target of an update action (kml:Create, kml:Delete, kml:Change) have a targetId attribute and do not have an id attribute

In the context of an AnimatedUpdate appearing in a Tour, an empty Update/targetHref element indicates that all elements to be updated occur in the same document.

Parameters:

updateNode - A node that represents a kml:Update element.

Returns:

true if no constraints are violated; false otherwise.
