Method Detail

getUIHints

public DirectiveUIHints getUIHints()

Specified by:

getUIHints in interface DirectiveUIHints.Provider

query

public java.util.ArrayList<ResultRow> query(QueryContext context,
                                            ResultRow input)
                                     throws QueryException

Description copied from class: Directive

Executes the query buffering all results in a list and returning that. This may be useful at the top level where the results are going to be retrieved entirely in a list anyway. Inside the query you should avoid using this as the intermediate results can become very large due to join operations. startQuery must have been called before calling this and endQuery after the query is done. If this is the top level directive you may have to do it manually. These call should propaget automaticall to all inner queries.

Overrides:

query in class Directive

Throws:

QueryException

queryIterator

public ResultIterator queryIterator(QueryContext context,
                                    ResultRow input)
                             throws QueryException

Description copied from class: Directive

You must call startQuery before calling this and endQuery after you are done with the result iterator. You should also call dispose of the result iterator when you're done.

Overrides:

queryIterator in class Directive

Throws:

QueryException

isStatic
