AbstractIntKeyIntOptimisticLockingDto

public AbstractIntKeyIntOptimisticLockingDto()

Method Detail

getKey

public int getKey()

Returns:

Returns the key.

getKeyAsObject

public Object getKeyAsObject()

Specified by:

getKeyAsObject in interface PrimaryKeyObject

Returns:

Returns the key as an object or null if it does not exist.

setKey

public void setKey(int key)

Parameters:

key - The key to set.

setKey

public void setKey(Object keyObject)

Convenience method to set the key. The given parameter must be an Number otherwise it will be rejected.

Specified by:

setKey in interface PrimaryKeyObject

Parameters:

keyObject - Is the key as object to set.

isKeyNew

public boolean isKeyNew()

Specified by:

isKeyNew in interface PrimaryKeyObject

Returns:

Returns true if the key has never be set by using method setKey.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

resetNew

public void resetNew()

Reset the key state to "new". This is required in some circumstances (offlining), otherwise it should NOT be used.

useGeneratedKey

public void useGeneratedKey()

This method will be called when the primary key object is requested to generate a key object for himself. Does nothing, because primary key will be generated by database.

Specified by:

useGeneratedKey in interface PrimaryKeyObject
