Parameters

xmlBase
Type: Tangosol.Run.XmlIXmlElement
Base IXmlElement.
xmlOverride
Type: Tangosol.Run.XmlIXmlElement
Override IXmlElement.
idAttrName
Type: SystemString
Attribute name that serves as an identifier allowing to match elements with the same name; if not specified all attributes have to match for an override.
Exceptions
ExceptionCondition
InvalidOperationException If the base element is immutable or there is ambiguity between the override and base elements.
Remarks
The values are only overriden if there is an exact match between the element paths and an attribute value for the specified attribute name. Empty override values are ignored. Override elements that do not match any of the base elements are just copied over. No ambiguity is allowed.
For example, if the base element has more then one child with the same name and the specified attribute's value then the override is not allowed.
