getUIHints

public DirectiveUIHints getUIHints()

Specified by:

getUIHints in interface DirectiveUIHints.Provider

startQuery

public boolean startQuery(QueryContext context)
                   throws QueryException

Description copied from class: Directive

Prepares the query for execution. Extending classes must propagate the call to any contained queries.

Overrides:

startQuery in class Directive

Throws:

QueryException

endQuery

public void endQuery(QueryContext context)
              throws QueryException

Description copied from class: Directive

Signals end of query and performs any cleanup that may be needed. Extending classes must propagate the call to any contained queries.

Overrides:

endQuery 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

debugStringParams

public java.lang.String debugStringParams(java.lang.String indent)

Overrides:

debugStringParams in class Directive
