Description copied from interface: PastContent

Checks if a insert operation should be allowed. Invoked when a Past node receives an insert request and it is a replica root for the id; invoked on the object to be inserted. This method determines the effect of an insert operation on an object that already exists: it computes the new value of the stored object, as a function of the new and the existing object.

Specified by:

checkInsert in interface PastContent

Overrides:

checkInsert in class DistPastRegrTest.TestPastContent

Parameters:

id - the key identifying the object

Returns:

null, if the operation is not allowed; else, the new object to be stored on the local node.
