Field Detail

m_iDomainId

protected int m_iDomainId

Id of the domain this data object belongs to. Domain represents default partition where the data object belongs to (since it is pressumed that each data object belongs to some partitions).

m_creationTimestamp

protected java.sql.Timestamp m_creationTimestamp

Creation timestamp when the data object was created.

Constructor Detail

BasicDataObject

public BasicDataObject()

Default constructor.

BasicDataObject

public BasicDataObject(int iDomainId)

Simple constructor creating new data object in particular domain.

Parameters:

iDomainId - - domain this data object belongs to

BasicDataObject

public BasicDataObject(int iId,
                       int iDomainId,
                       java.sql.Timestamp creationTimestamp)

Full constructor.

Parameters:

iId - - id of this data object

iDomainId - - domain this data object belongs to

creationTimestamp - - timestamp when the data object was created.

Method Detail

getDomainId

public int getDomainId()

Returns:

int

getId

public int getId()

Get the id uniquely identifying the object.

Specified by:

getId in class DataObject

Returns:

int

getIdAsObject

public java.lang.Integer getIdAsObject()

Get the id as object uniquely identifying the object. This method allows to the implementing class to cache this object if desired to improve performance.

Specified by:

getIdAsObject in class DataObject

Returns:

Integer

setId

public void setId(int iNewId)

Parameters:

iNewId - - new id of the data object

getCreationTimestamp

public java.sql.Timestamp getCreationTimestamp()

Creation timestamp is timestamp when the data object was created.

Returns:

Timestamp

setCreationTimestamp

public void setCreationTimestamp(java.sql.Timestamp creationTimestamp)

Creation timestamp is timestamp when the data object was created.

Parameters:

creationTimestamp - - new creation timestamp

equals

public boolean equals(java.lang.Object oObject)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

restore

protected void restore(int iId,
                       int iDomainId,
                       java.sql.Timestamp creationTimestamp)

Restore all values from specified values. This is here to reinitialize object in case it needs to be reused or reconstructed (e.g. when rollback is issued).

Parameters:

iId - - id of this data object

iDomainId - - domain this data object belongs to

creationTimestamp - - timestamp when the data object was created.
