TransactionAnswer

public TransactionAnswer()

Method Detail

ofNOP

public static final TransactionAnswer ofNOP(Transaction _tx)

Creates a placeholder TransactionAnswer with a placeholder TransactionConflictReport for transactions that are saved but have no actual changes.

This method is useful for scenarios where a transaction has been saved, but no modifications were made to any business objects. It returns a `TransactionAnswer` with a placeholder `TransactionConflictReport` to indicate a successful, but effectively no-op, transaction.

Parameters:

_tx - The transaction that was saved without any changes.

Returns:

A `TransactionAnswer` with a placeholder `TransactionConflictReport` for a no-op transaction.

isNOP

public boolean isNOP()

Checks if this TransactionAnswer is a placeholder for a "no-operation" (NOP) transaction.

A NOP transaction is one that has been saved but has not resulted in any actual changes to the underlying data.

Returns:

`true` if this TransactionAnswer is a placeholder a NOP transaction, `false` otherwise.

isConflict

public boolean isConflict()

Returns true if the TransactionConflictReport of this TransactionAnswer is set and represents an actual conflict.

destubAndInclude

public static BO destubAndInclude(BO stub,
                                  Transaction destubTx)

Returns the "real" BO for the passed "stubbed" BO via the passed Transaction. "Stubs" contain only the Id and clazz (i.e. BOT) of a BO. The "real" BO will be included in the same Transaction the "stub" was included in, if any.

setAdditionalBOProcs

public void setAdditionalBOProcs(BOProc[] addProcs)

hasAdditionalBOProcs

public boolean hasAdditionalBOProcs()

Returns true if this TransactionAnswer contains any additional procs.
