Method Detail

code

public String code()

Four character representation of the state.

The format is XYZ where:

• X is transient state:
  • N
  for New
  • T
  for Transient
  • P
  for Persistent
  • D
  for Destroyed
  • V
  for Value
• Y (for persistent only) is the resolve state:
  • G
  for Ghost
  • R
  for Resolved
  • r
  for resolving
  • ~
  if not persistent
• Z (for non-standalone, not resolving, not updating, not destroyed) is the serialization state:
  • ~
  not serializing
  • S
  is serializing

getEndState

public ResolveState getEndState()

representsPersistent

public boolean representsPersistent()

Returns true when an object is persistent (except for VALUE adapters).

Always returns false for VALUE.

canTransitionToResolving

public boolean canTransitionToResolving()

As per isValidToChangeTo(ResolveState), but will additionally return false if the current state can never be transitioned from.

respondToChangesInPersistentObjects

public boolean respondToChangesInPersistentObjects()

Returns false while object is having its field set up.

isNew

public boolean isNew()

isValue

public boolean isValue()

isTransient

public boolean isTransient()

isGhost

public boolean isGhost()

isUpdating

public boolean isUpdating()

isResolved

public boolean isResolved()

isResolving

public boolean isResolving()

isDestroyed

public boolean isDestroyed()

isValidToChangeTo

public boolean isValidToChangeTo(ResolveState nextState)

Determines if the resolved state can be changed from this state to the specified state. Returns true if the change is valid.

name

public String name()

toString

public String toString()

Overrides:
