Method Detail

entityReference

EntityReference entityReference()

Returns the reference of the entity that this EntityState represents.

Returns:

the reference of the entity that this EntityState represents.

remove

void remove()

Remove the entity represented by this EntityState when the unit of work is completed.

status

EntityStatus status()

The status of this EntityState

Returns:

the status

isAssignableTo
