Method Detail

isTransientLost

boolean isTransientLost()

If returns true means all transient values were lost.

Typically can use a transient field that we know on construction is set to the opposite. If the field value is default then we know transient values were lost.

recoverTransient

void recoverTransient()

If isTransientLost() then a way to recover its transient values.

Typically, one can internally keep the id in the context (example BeanNameAware), of the Model from where it came and on isTransientLost() true recover by getting it back for the context.
