public interface Join

extends OWBNamedObject, Extensible

A Join represents a join from the current Query Object to another Query Object.

Method Summary

JoinComponent	createJoinComponent(java.lang.String name) Creates a new Join Component at the end of the list of Join Components for this Join.
JoinComponent	findJoinComponent(java.lang.String name) Search for a join component of this join by name.
java.lang.String	getExternalKeyName() Returns the external name for the corresponding foreign key.

QueryObject	getOwningQueryObject() Returns the owning query object.
QueryObject	getReferencedQueryObject() Returns the referenced query object.
ForeignKey	getRelatedForeignKey() Returns the corresponding relational foreign key.
boolean	isAllowDetailNoMaster() Returns whether to generate a (+) on the detail side of the join.
boolean	isAllowMasterNoDetail() Returns whether to generate a (+) on the master side of the join.
boolean	isMandatory() Returns whether it is a "no loss" join; i.e. whether every detail row must reference a unique master row.
boolean	isOneToOne() Returns whether the join is a one-to-one relationship between master and detail.
void	setAllowDetailNoMaster(boolean allowDetailNoMaster) Sets whether to generate a (+) on the detail side of the join.
void	setAllowMasterNoDetail(boolean allowMasterNoDetail) Sets whether to generate a (+) on the master side of the join.
void	setExternalKeyName(java.lang.String externalKeyName) Sets the external name for the corresponding foreign key.
void	setMandatory(boolean mandatory) Sets whether every detail row must reference a unique master row.
void	setOneToOne(boolean oneToOne) Sets whether the join is a one-to-one relationship.
void	setReferencedQueryObject(QueryObject queryObject) Sets the query object referenced by the Join.
void	setRelatedForeignKey(ForeignKey foreignKey) Sets the relational foreign key corresponding to the Join.

Method Detail

isAllowDetailNoMaster

public boolean isAllowDetailNoMaster()

Returns whether to generate a (+) on the detail side of the join.

Returns:

true if a detail row in this Join may have no master row.

See Also:

setAllowDetailNoMaster(boolean)

setAllowDetailNoMaster

public void setAllowDetailNoMaster(boolean allowDetailNoMaster)

Sets whether to generate a (+) on the detail side of the join.

Parameters:

allowDetailNoMaster - true if a detail row in this Join may have no master row.

See Also:

isAllowDetailNoMaster()

isAllowMasterNoDetail

public boolean isAllowMasterNoDetail()

Returns whether to generate a (+) on the master side of the join.

Returns:

true if a master row in this Join may have no detail rows.

See Also:

setAllowMasterNoDetail(boolean)

setAllowMasterNoDetail

public void setAllowMasterNoDetail(boolean allowMasterNoDetail)

Sets whether to generate a (+) on the master side of the join.

Parameters:

allowMasterNoDetail - true if a master row in this Join may have no detail rows.

See Also:

isAllowMasterNoDetail()

getExternalKeyName

public java.lang.String getExternalKeyName()

Returns the external name for the corresponding foreign key. (This is only relevant for a join that corresponds to a database foreign key.)

Returns:

a String representing the external name for the key.

See Also:

setExternalKeyName(java.lang.String)

setExternalKeyName

public void setExternalKeyName(java.lang.String externalKeyName)

Sets the external name for the corresponding foreign key.

Parameters:

externalKeyName - a String specifying the external name for the key.

See Also:

getExternalKeyName()

isMandatory

public boolean isMandatory()

Returns whether it is a "no loss" join; i.e. whether every detail row must reference a unique master row.

Returns:

true if every detail row must reference a unique master row.

See Also:

setMandatory(boolean)

setMandatory

public void setMandatory(boolean mandatory)

Sets whether every detail row must reference a unique master row.

Parameters:

mandatory - true if every detail row must reference a unique master row.

See Also:

isMandatory()

isOneToOne

public boolean isOneToOne()

Returns whether the join is a one-to-one relationship between master and detail.

Returns:

true if this join is a one-to-one relationship.

See Also:

setOneToOne(boolean)

setOneToOne

public void setOneToOne(boolean oneToOne)

Sets whether the join is a one-to-one relationship.

Parameters:

oneToOne - true if this join is a one-to-one relationship.

isOneToOne()

getOwningQueryObject

public QueryObject getOwningQueryObject()

Returns the owning query object.

Returns:

a QueryObject representing the query object that owns the join.

setReferencedQueryObject

public void setReferencedQueryObject(QueryObject queryObject)
