Class SubstituteString

java.lang.Object
com.yahoo.search.query.profile.SubstituteString
public class SubstituteString extends Object
A string which contains one or more elements of the form %{name}, where these occurrences are to be replaced by a query profile lookup on name.

This objects does the analysis on creation and provides a (reasonably) fast method of performing the actual substitution (at lookup time).

This is a value object. Lookups in this are thread safe.
