SHIN HWEI TAN commented on XALANJ-2553:
---------------------------------------
The Javadoc comments reported above are referring to the @param transformer
Non-null transformer instance reference tag in the
transformer/SerializerSwitcher.java file.
The Javadoc comments in the TreeWalker2Result.java file are the same but the
method behaves differently. In the SerializerSwitcher class, the method has a
check for null transformer but simply return normally. In contrast, in the
TreeWalker2Result class, the TreeWalker2Result(TransformerImpl
,SerializationHandler) constructor does not have any check for null
transformer.
> Inconsistent Javadoc comment and code for
> switchSerializerIfHTML(TransformerImpl, String, String) in
> org.apache.xalan.transformer.SerializerSwitcher

> Components: Xalan

> The Javadoc comment below states that the parameter transformer "Non-null
> transformer instance":
> /**
> * ..
> * @param transformer Non-null transformer instance
> * @param ns Namespace URI of the element
> * @param localName Local part of name of element
> *...
> */
> public static void switchSerializerIfHTML(TransformerImpl transformer,
> String ns, String localName)
> However, the method return normally without throwing any exception when
> called with a null transformer.
> Suggested Fixes:
> 1. Change "@param transformer Non-null transformer instance" to "@param
> transformer transformer instance, null will be ignored"
> or
> 2. Remove "Non-null" from @param.
