Method Detail

ofNOP

public static final TransactionAnswer ofNOP(Transaction _tx)

Creates a placeholder TransactionAnswer for transactions containing no modifications.

Parameters:

_tx - the empty transaction

Returns:

a no-op TransactionAnswer containing an empty TransactionConflictReport

isNOP

public boolean isNOP()

Returns whether this response represents a no-operation (NOP) transaction where no underlying data was modified.

Returns:

true if this represents a NOP transaction, false otherwise

isConflict

public boolean isConflict()

Returns whether this answer contains an active concurrency conflict.

Returns:

true if a conflict report exists and indicates a conflict, false otherwise

destubAndInclude

public static BO destubAndInclude(BO stub,
                                  Transaction destubTx)

Resolves a stubbed business object using destubTx and includes the resulting full instance in the stub’s original transaction, if one was attached.

Parameters:

stub - the lightweight business object stub to resolve

destubTx - the transaction context used to load the full business object

Returns:

the resolved full BO, included in the stub’s transaction if present

setAdditionalBOProcs

public void setAdditionalBOProcs(BOProc[] addProcs)

Sets the additional business procedures generated during processing.

Parameters:

addProcs - the business procedures to attach

getAdditionalProcs

public BOProc[] getAdditionalProcs()

Returns any additional business procedures generated during transaction persistence.

Returns:

array of business procedures, or null if none were attached

hasAdditionalBOProcs
