Class TimedRelation

java.lang.Object
  pl.edu.agh.cast.model.mapper.AbstractMappable
      pl.edu.agh.cast.model.base.Relation
          pl.edu.agh.cast.model.base.TimedRelation

All Implemented Interfaces:

Serializable, Cloneable, IRelation, ITimedRelation, Mappable

@Mapping
public class TimedRelation
extends Relation
implements ITimedRelation

The timed relation represents relation with assigned date. The date might be used to order relations in time-line editor.

Constructor Summary

TimedRelation()
Default constructor.

TimedRelation(IEntity src, IEntity dst, Date newDate)
Parameterized constructor.

Method Summary

boolean	equals(Object other) Two Timed relations are equal if their source and target nodes have the same id and their dates are equal.
boolean	fixedEquals(ITimedRelation relation) Checks if given timed relation is equal in terms of timed relation not the domain-specific sense, to the given timed relation.
Date	getDate() Get the date of the relation.
int	getFixedHashCode() Remark: the hash code of the id of the TimedRelation is dependent on all the data which are checked in the equals method, because the id is constructed of the source and target nodes IDs and the date.
ITimedRelation	getTimedRelation() Returns object of class TimedRelation no matter if the object is of class ITimedRelation or class which inherits from it.
int	hashCode()
void	setDate(Date newDate) Set the date of the relation.
protected void	updateId()

Field Detail

date

protected Date date

The date of the relation.

Constructor Detail

TimedRelation

public TimedRelation()

Default constructor.

TimedRelation

public TimedRelation(IEntity src,
                     IEntity dst,
                     Date newDate)

Parameterized constructor.

Parameters:

src - The source of the relation

dst - The target of the relations

newDate - The date of occurrence of the relation.

Method Detail

getDate

@MapAttribute(typeName="Date")
public Date getDate()

Get the date of the relation.

Specified by:

getDate in interface ITimedRelation

Returns:

The date.

setDate

public void setDate(Date newDate)

Set the date of the relation.

Parameters:

newDate - the date to set

updateId

protected void updateId()

Overrides:

updateId in class Relation

equals

public boolean equals(Object other)

Two Timed relations are equal if their source and target nodes have the same id and their dates are equal.

Overrides:

equals in class Relation

Parameters:

other - object to check

Returns:

true if the other relation is equal to this relation.

hashCode

public int hashCode()

Overrides:

hashCode in class Relation

See Also:

Relation.hashCode()

getTimedRelation

public final ITimedRelation getTimedRelation()

Returns object of class TimedRelation no matter if the object is of class ITimedRelation or class which inherits from it.

Specified by:

getTimedRelation in interface ITimedRelation

Returns:

The object of class TimedRelation.

getFixedHashCode

public final int getFixedHashCode()

Remark: the hash code of the id of the TimedRelation is dependent on all the data which are checked in the equals method, because the id is constructed of the source and target nodes IDs and the date.

Specified by:

getFixedHashCode in interface ITimedRelation

Returns:

The hash code of the timed relation.

fixedEquals

public final boolean fixedEquals(ITimedRelation relation)

Checks if given timed relation is equal in terms of timed relation not the domain-specific sense, to the given timed relation.

Specified by:

fixedEquals in interface ITimedRelation

Parameters:

relation - The relation which is checked for equality.

Returns:

True if source, target and the date of both relations are equal.
