Class DumbDB  

java.lang.Object
  com.sample.addressbook.dumbdb.DumbDB

---

public class DumbDB

extends java.lang.Object

This class is used to fake a dumb database.

It is only used for this application so that it can be demonstrated without the need of a proper database.

Please do not use this class for anything other than testing/prototype purposes.

Method Detail

getDumbDB

---

getIncrement

public int getIncrement()

---

setIncrement

public void setIncrement(int inc)

---

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

---

getObjectById

public java.lang.Object getObjectById(java.lang.String id)

Get an object from the db by it's ID.

---

updateObjectById

public void updateObjectById(java.lang.String id,
                             java.lang.Object data)

Update an object in the db by it's ID.

---

deleteObjectById

public void deleteObjectById(java.lang.String id)

Delete an object in the db by it's ID.

---

insertObject

public void insertObject(java.lang.Object data)

Insert an object into the db by it's ID.

---

getObjectByAttributeValues
