Specified by:

genId in interface LongGen

Returns:

The new identifier.

getMemoryInstance

public java.lang.Object getMemoryInstance()

It returns the memory instance within which the persistent variables are defined.

Specified by:

getMemoryInstance in interface PAccessor

Returns:

The actual object containing memory persistent variables.

paGetNextId

public long paGetNextId()

nextId getter.

paSetNextId

public void paSetNextId(long val)
