Constructor Detail

RecoveryAwareDldGlobalTransaction.Externalizer

public RecoveryAwareDldGlobalTransaction.Externalizer()
Method Detail

writeObject

public void writeObject(ObjectOutput output,
                        RecoveryAwareDldGlobalTransaction globalTransaction)
                 throws IOException
Description copied from interface: Externalizer
Write the object reference to the stream.

Specified by:
writeObject in interface Externalizer<RecoveryAwareDldGlobalTransaction>
Overrides:
writeObject in class GlobalTransaction.AbstractGlobalTxExternalizer<RecoveryAwareDldGlobalTransaction>
Parameters:
output - the object output to write to
globalTransaction - the object reference to write
Throws:
IOException - if an I/O error occurs

createGlobalTransaction

protected RecoveryAwareDldGlobalTransaction createGlobalTransaction()
Description copied from class: GlobalTransaction.AbstractGlobalTxExternalizer
Factory method for GlobalTransactions

Specified by:
createGlobalTransaction in class GlobalTransaction.AbstractGlobalTxExternalizer<RecoveryAwareDldGlobalTransaction>
Returns:
a newly constructed instance of GlobalTransaction or one of its subclasses

readObject

public RecoveryAwareDldGlobalTransaction readObject(ObjectInput input)
                                             throws IOException,
                                                    ClassNotFoundException
Description copied from interface: Externalizer
Read an instance from the stream. The instance will have been written by the Externalizer.writeObject(ObjectOutput, Object) method. Implementations are free to create instances of the object read from the stream in any way that they feel like. This could be via constructor, factory or reflection.

Specified by:
readObject in interface Externalizer<RecoveryAwareDldGlobalTransaction>
Overrides:
readObject in class GlobalTransaction.AbstractGlobalTxExternalizer<RecoveryAwareDldGlobalTransaction>
Parameters:
input - the object input to read from
Returns:
the object instance
Throws:
IOException - if an I/O error occurs
ClassNotFoundException - if a class could not be found

getId

public Integer getId()
Description copied from interface: AdvancedExternalizer
Returns an integer that identifies the externalizer type. This is used at read time to figure out which AdvancedExternalizer should read the contents of the incoming buffer. Using a positive integer allows for very efficient variable length encoding of numbers, and it's much more efficient than shipping AdvancedExternalizer implementation class information around. Negative values are not allowed. Implementers of this interface can use any positive integer as long as it does not clash with any other identifier in the system. You can find information on the pre-assigned identifier ranges in here. It's highly recommended that maintaining of these identifiers is done in a centralized way and you can do so by making annotations reference a set of statically defined identifiers in a separate class or interface. Such class/interface gives a global view of the identifiers in use and so can make it easier to assign new ids. Implementors can optionally avoid giving a meaningful implementation to this method (i.e. return null) and instead rely on XML or programmatic configuration to provide the AdvancedExternalizer id. If no id can be determined via the implementation or XML/programmatic configuration, an error will be reported. If an id has been defined both via the implementation and XML/programmatic configuration, the value defined via XML/programmatic configuration will be used ignoring the other.

Specified by:
getId in interface AdvancedExternalizer<RecoveryAwareDldGlobalTransaction>
Overrides:
getId in class AbstractExternalizer<RecoveryAwareDldGlobalTransaction>
Returns:
A positive identifier for the AdvancedExternalizer.

getTypeClasses

public Set<Class<? extends RecoveryAwareDldGlobalTransaction>> getTypeClasses()
Description copied from interface: AdvancedExternalizer
Returns a collection of Class instances representing the types that this AdvancedExternalizer can marshall. Clearly, empty sets are not allowed. The externalizer framework currently requires all individual types to be listed since it does not make assumptions based on super classes or interfaces.

Returns:
A set containing the Class instances that can be marshalled.
