Method Detail

getId

public ID getId()

Description copied from interface: HasId

Get unique object identifier for this object.

Specified by:

getId in interface HasId<ID>

Returns:

id

getEquandaModificationDate

public Timestamp getEquandaModificationDate()

getEquandaVersion

public long getEquandaVersion()

isEquandaModificationDateModified

public boolean isEquandaModificationDateModified()

getEquandaStatus

public abstract String getEquandaStatus()

setEquandaStatus

public abstract void setEquandaStatus(String status)

getEquandaType

public String getEquandaType()

getEquandaName

public String getEquandaName()

isEquandaType

public boolean isEquandaType(String type)

toString

public String toString()

Overrides:

toString in class Object

setEquandaType

public abstract void setEquandaType(String type)

Set the type of object which should be used. This is a helper routine to allow using isEquandaType() for checking of object type. This method is only allowed for object building (not for objects which already exists on the server. When an invalid type identifier is specified, then later calls to read the type will throw IllegalStateException.

Parameters:

type - base type which will be used to build the actual object

Throws:

IllegalStateException

isModified

public abstract boolean isModified(boolean typeFieldsOnly)

isModified

public boolean isModified()

objectEquals

protected boolean objectEquals(Object obj1,
                               Object obj2)

utility routine to test equality of objects without relying on one of them being not null.

Parameters:

obj1 - one of the objects to compare

obj2 - other object to compare

Returns:

true when bot objects are equal

equandaClone

public PROXY equandaClone()

equandaClone

public abstract PROXY equandaClone(boolean cloneUoid)

equandaUpdate

public void equandaUpdate()
                   throws EquandaException

Update the proxy state, client changes are persisted, and server changes retrieved.

Throws:

EquandaException - update problems

equandaUpdate

public abstract void equandaUpdate(boolean updateTypeFieldsOnly)
                            throws EquandaException

Throws:

EquandaException

equandaReset

public abstract void equandaReset()
                           throws EquandaException

Reset the proxy state. If the proxy was not modified, nothing happens, otherwise the state is retrieved from the server again.

Throws:

EquandaException - oops

removeEntityBean

public void removeEntityBean()
                      throws EquandaException

Throws:

EquandaException

setEquandaUpdate

public void setEquandaUpdate(boolean update)

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
