| Method Summary | |
| public BasicAggregatedField | addAggregatedField(Step step, CoreField field, int aggregationType)
Adds new aggregated field to this SearchQuery.
Parameters:
step - The associated step.
Parameters:
field - The associated Field.
Parameters:
aggregationType - The aggregation type. | | public BasicStepField | addField(Step step, CoreField fieldDefs)
Adds new field to this SearchQuery.
Parameters:
step - The associated step.
Parameters:
fieldDefs - The associated fieldDefs. | | public BasicStepField | addFieldUnlessPresent(Step step, CoreField fieldDefs)
| | public void | addFields(Step step)
| | public BasicRelationStep | addRelationStep(InsRel builder, MMObjectBuilder nextBuilder)
Adds new relationstep to this SearchQuery.
This adds the next step as well, it can be retrieved by calling
org.mmbase.storage.search.RelationStep.getNext getNext() on the relationstep, and cast to
BasicStep BasicStep .
Parameters:
builder - The builder associated with the relation step.
Parameters:
nextBuilder - The builder associated with the next step. | | public BasicSortOrder | addSortOrder(StepField field)
Creates sortorder for this SearchQuery.
Parameters:
field - The associated stepfield. | | public BasicStep | addStep(MMObjectBuilder builder)
Adds new step to this SearchQuery.
Parameters:
builder - The builder associated with the step. | | public Object | clone()

| | protected void | copySteps(SearchQuery q)
| | protected static StepField | createNewStepField(SearchQuery q, StepField f)
Creates a new StepField like f for query q. | | public boolean | equals(Object obj)

| BasicSearchQuery | | public BasicSearchQuery(boolean aggregating)(Code) | | Constructor.
Parameters:
aggregating - True for an aggregating query, false otherwise. |
| BasicSearchQuery | | public BasicSearchQuery()(Code) | | Constructor, constructs non-aggragating query.
|
| BasicSearchQuery | | public BasicSearchQuery(SearchQuery q, int copyMethod)(Code) | | A deep copy, but sets also aggregating, and clear fields if aggregating is true then.
|
| BasicSearchQuery | | public BasicSearchQuery(SearchQuery q)(Code) | | A deep copy. Needed if you want to do multiple queries (and change the query between them).
Used by bridge.Query#clone (so it will be decided that that is not needed, ths can be removed too)
