public interface IQueryParticipant
This is the interface expected of extensions to the extension point
IQueryParticipant is called during the execution of a
Java search query. It can report matches via an
may contribute a
IMatchPresentation to help render the elements it contributes.
Clients may implement this interface.
- Executes the search described by the given
querySpecification. Matches are reported

The interpretation of what a given Java search (e.g. "References to class Foo") means is up to the
requestor - The requester to report matches to.
querySpecification - The specification of the query to run.
monitor - A monitor to report progress on.
- Thrown when the search can not be executed
- Returns the number of units of work estimated. The returned number should be normalized such
that the number of ticks for the original Java search job is 1000. For example if the participant
uses the same amount of time as the Java search, it should return 1000, if it uses half the time,
it should return 500, etc.
This method is supposed to give a quick estimate of the work to be done and is assumed
to be much faster than the actual query.
specification - the specification to estimate.
- The number of ticks estimated.
- Gets the UI participant responsible for handling the display of elements not known to the Java search UI. The Java search UI knows
elements are of type
A participant may return
null if matches are only reported against elements of type
