Constructor Detail

Collision

public Collision(int id)
          throws JetWebException

Create a collision from a unique collision ID.

Throws:

JetWebException

Collision

public Collision()

Create an empty collision.

Method Detail

addParticle

public Collision addParticle(Particle p,
                             java.lang.Integer pNumber)
                      throws JetWebException

Throws:

JetWebException

addParticle

public void addParticle(Particle p)
                 throws JetWebException

Throws:

JetWebException

getParticles

public java.util.Collection<Particle> getParticles()

getNumberOfParticles

public java.lang.Integer getNumberOfParticles()

setId

public void setId(int id)

getParticle1

public Particle getParticle1()

getParticle2

public Particle getParticle2()

equals

public boolean equals(java.lang.Object obj)

Override the Object equals method. Use the processId.

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

getId

public int getId()

Description copied from interface: Storeable

Get the unique ID of the object

Specified by:

getId in interface Storeable

retrieve

public boolean retrieve()
                 throws JetWebException

Description copied from interface: Storeable

Populate the object in memory from the database. Return true if the information retrieved is up to date.

Specified by:

retrieve in interface Storeable

Throws:

JetWebException

store

public boolean store()
              throws JetWebException

Description copied from interface: Storeable

Write the object in memory to the database. If the ID does not exist in the DB the object is inserted as a new entry. If the ID exists, that entry is updated.

Specified by:

store in interface Storeable

Returns:

true if the object was inserted, false otherwise.

Throws:

JetWebException

getCMEnergy

public double getCMEnergy()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
