Method Detail

getResolveState

public static ResolveState getResolveState(java.lang.String name)

code

public java.lang.String code()

Four character representation of the state.

The format is XYZW where:

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

getEndState

public ResolveState getEndState()

isPersistent

public boolean isPersistent()

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

Always returns false for VALUE.

isTransient

public boolean isTransient()

Returns true when an object has not yet been made persistent (except for VALUE adapters)..

Always returns false for VALUE.

canChangeTo

public boolean canChangeTo(ResolveState newState)

As per isValidToChangeTo(ResolveState), but will additionally throw a ResolveException if the requested state can never be transitioned into, and will return false if the current state can never be transitioned from.

isResolvable

@Deprecated
public boolean isResolvable(ResolveState newState)

Deprecated. - renamed to canChangeTo(ResolveState).

isDeserializable

isResolved

public boolean isResolved()

isResolving

public boolean isResolving()

Return true if the state reflects some kind of loading.

couldResolve

public boolean couldResolve()

Returns true if an object in this state could trigger some sort of database loading.

Used to prevent calls to title() etc on objects that are not resolved.
