io.ebeaninternal.api.ManyWhereJoins

All Implemented Interfaces:

Serializable

public class ManyWhereJoins
extends Object
implements Serializable

Holds the joins needs to support the many where predicates. These joins are independent of any 'fetch' joins on the many.

Method Summary

Modifier and Type	Method	Description
void	add(ElPropertyDeploy elProp)	Add a many where join.
void	addAggregationJoin(String property)	Ensure we have the join required to support the aggregation properties.
void	addFormulaWithJoin(String propertyName)	In findCount query found a formula property with a join clause so building a select clause specifically for the findCount query.
List<String>	getFormulaJoinProperties()	Return the formula properties to build the select clause for a findCount query.
Collection<PropertyJoin>	getPropertyJoins()	Return the set of many where joins.
TreeSet<String>	getPropertyNames()	Return the set of property names for the many where joins.
boolean	isFormulaWithJoin()	Return true if the query select includes a formula with join.
boolean	isRequireOuterJoins()	Return the current 'mode' indicating if outer joins are currently required or not.
boolean	requireSqlDistinct()	Return true if this is an aggregation query or if there are no extra many where joins.
void	setAggregation()	Mark this as part of an aggregation query (so using group by clause).
void	setRequireOuterJoins(boolean requireOuterJoins)	Set the 'mode' to be that joins added are required to be outer joins.

ManyWhereJoins

public ManyWhereJoins()

Method Detail

isRequireOuterJoins

public boolean isRequireOuterJoins()

Return the current 'mode' indicating if outer joins are currently required or not.

setRequireOuterJoins

public void setRequireOuterJoins(boolean requireOuterJoins)

Set the 'mode' to be that joins added are required to be outer joins. This is set during the evaluation of disjunction predicates.

add

public void add(ElPropertyDeploy elProp)

Add a many where join.

requireSqlDistinct

public boolean requireSqlDistinct()

Return true if this is an aggregation query or if there are no extra many where joins.

getPropertyJoins

public Collection<PropertyJoin> getPropertyJoins()

Return the set of many where joins.

getPropertyNames

public TreeSet<String> getPropertyNames()

Return the set of property names for the many where joins.

addFormulaWithJoin

public void addFormulaWithJoin(String propertyName)

In findCount query found a formula property with a join clause so building a select clause specifically for the findCount query.

isFormulaWithJoin

public boolean isFormulaWithJoin()

Return true if the query select includes a formula with join.

getFormulaJoinProperties

public List<String> getFormulaJoinProperties()

Return the formula properties to build the select clause for a findCount query.

setAggregation

public void setAggregation()

Mark this as part of an aggregation query (so using group by clause).

addAggregationJoin

public void addAggregationJoin(String property)

Ensure we have the join required to support the aggregation properties.
