setAttributeName

public void setAttributeName(java.lang.String attrName)

setDescending

public void setDescending(boolean isDescending)

writeContents

public void writeContents(DefWriter jos)

Description copied from interface: PersistentDefinition

Objects should write their persistence output in this method

Specified by:

writeContents in interface PersistentDefinition

Parameters:

jos - the Output storage for persistence

loadXMLContents

public void loadXMLContents(DefElement xmlElement)

getXMLElementTag

public java.lang.String getXMLElementTag()

Description copied from interface: PersistentDefinition

Returns a piece of static info for the type of object this is invoked upon. Examples are PreparedStatements for insert, update, delete, and String containing a base the select statement for retrieving instances of this type through the SQLInputStream

Specified by:

getXMLElementTag in interface PersistentDefinition

Returns:

returns the Statement required to store in Persitent Storage. Incase of XML, it just returns the String. In the case of SQL a JDBC PreparedStatement is returned.

getDefXMLElementTag

public java.lang.String getDefXMLElementTag()

Specified by:

getDefXMLElementTag in interface PersistentDefinition

getDefXMLNameSpace

public java.lang.String getDefXMLNameSpace()

Specified by:

getDefXMLNameSpace in interface PersistentDefinition

isNew

public boolean isNew()

Description copied from interface: DefPersistable

This method returns if this object is previously persisted.

Specified by:

isNew in interface DefPersistable

Returns:

true if the Object is previously persisted. Returns false otherwise.

setNew

public void setNew(boolean b)

Description copied from interface: DefPersistable

This method marks the as previously persisted. By default all objects are new objects. When the object is persisted first time, that object is marked as 'not new' object

Specified by:

setNew in interface DefPersistable

Parameters:

b - If true the Object is marked as new object.

getOrigObject

public DefPersistable getOrigObject()

Specified by:

getOrigObject in interface DefPersistable

setOrigObject

public void setOrigObject(DefPersistable oldObj)

Specified by:

setOrigObject in interface DefPersistable

getFullName

public java.lang.String getFullName()

Description copied from interface: DefPersistable

This method returns the Persistence reference of the object. The Persistence Reference is uniquely identifiable fully qualified name of the object.

Specified by:

getFullName in interface DefPersistable

Returns:

the Persistence Reference of the object

writeObject

public void writeObject(DefWriter jos)

Description copied from interface: PersistentDefinition

Objects should write their persistence output in this method

Specified by:

writeObject in interface PersistentDefinition

Parameters:

jos - the Output storage for persistence

writeChildren

public final void writeChildren(DefWriter jos)
                         throws DefPersistenceException

Description copied from interface: PersistentDefinition

Writes the Object's children to the Persistent storage

Specified by:

writeChildren in interface PersistentDefinition

Parameters:

jos - the Output storage for persistence

Throws:

DefPersistenceException

isDirty

public boolean isDirty()

Description copied from interface: DefPersistable

This method returns if an Object is modified from last save/load

Specified by:

isDirty in interface DefPersistable

Returns:

Returns true if the Object is dirty. Returns false otherwise.
