All Implemented Interfaces:

VectorState

Enclosing class:

NullVectorState

public static class NullVectorState.UnmanagedVectorState
extends NullVectorState

Near-do-nothing state for a vector that requires no work to allocate or roll-over, but where we do want to at least track the vector itself. (Used for map and union pseudo-vectors.)
