Constructor Summary

protected

TheRelation() The no-arg constructor.

Method Summary

<R extends TheRelation> Kin<R,R>	asKin() This doesn't provide type safety but to enable generic casts for subclasses.
TheRelation	getO() Get the related object of this kin.
short	getOnlinePriority() It might be a little memory economic that load relations after plain objects for the reduced trigger queue size during chained loading processes.
TheRelation	getR() Get the source relation object of this kin.
int	getTieCount() This method will be overrided by TOB generated code and return the calculated count of tie fields of the actual relation class.

Method Detail

asKin

public <R extends TheRelation> Kin<R,R> asKin()

This doesn't provide type safety but to enable generic casts for subclasses.

Type Parameters:

R - must be assignable from the actual instance.

Returns:

the same relation object with specified R as both the source relation type and the related object type

getR

public TheRelation getR()

Description copied from interface: Kin

Get the source relation object of this kin.

Specified by:

getR in interface Kin<TheRelation,TheRelation>

Returns:

this relation object

getO

public TheRelation getO()

Description copied from interface: Kin

Get the related object of this kin.

Specified by:

getO in interface Kin<TheRelation,TheRelation>

Returns:

this relation object

getTieCount

public int getTieCount()

This method will be overrided by TOB generated code and return the calculated count of tie fields of the actual relation class.

-1 will be returned by a non-born object.

Returns:

how many tie fields the relation class actually has, or -1 if not invoked against a born object

getOnlinePriority

public short getOnlinePriority()

It might be a little memory economic that load relations after plain objects for the reduced trigger queue size during chained loading processes. So get it some bigger than the value of TheObject.getOnlinePriority().

Overrides:

getOnlinePriority in class TheObject

Returns:

the online priority for this object. approximately 100 * the percentage of free memory in jvm above which this object should be kept online.
