Interface ResultType

All Known Subinterfaces:

ResultTypeKeyPath, ResultTypeKeyPathValue, ResultTypeString, ResultTypeTag

public interface ResultType

Specifies the result type from XPath query.

The query is issued trough Maapi.queryStart(int,String,String,int,int,List,Class) where the result type (the last parameter) is supplied as the class token corresponding to the specific sub type of this interface.

The results can be returned as subtype of this interface:

• strings, String ResultTypeString
• hkeypaths, array of ConfObject[] ResultTypeKeyPath
• hkeypaths and values, array of ConfObject[] and ConfValue ResultTypeKeyPathValue
• tag and values, ConfXMLParam ResultTypeTag

The string is just the resulting string of evaluating the select XPath expression.

For hkeypaths, tags, and values it is the path/tag/value of the node that the select XPath expression evaluates to. This means that care must be taken so that the combination of select expression and return types actually yield sensible results.

For example "1 + 2" is a valid select XPath expression, and would result in the string "3" when setting the result type to ResultTypeString but it is not a node, and thus have no hkeypath, tag, or value.
