Constructor Details

IUProfilePropertyQuery

public IUProfilePropertyQuery(String propertyName,
 String propertyValue)

Creates a new query on the given property name and value. Because the queryable for this query is typically the profile instance, we use a reference to the profile rather than the profile id for performance reasons.

Parameters:

propertyName - The name of the property to match

propertyValue - The value to compare to. A value of ANY will match any value.
