Method Detail

getId

byte getId()

You need to always return what was sent by setId. This is to enable Streaming to discover what Persister to use

setId

void setId(byte id)

writeData

void writeData(ClassMetaData metaData,
             ObjectOutput out,
             Object obj,
             ObjectSubstitutionInterface substitution)
               throws IOException

Throws:

IOException

readData

Object readData(ClassLoader loader,
              StreamingClass streaming,
              ClassMetaData metaData,
              int referenceId,
              ObjectsCache cache,
              ObjectInput input,
              ObjectSubstitutionInterface substitution)
                throws IOException

Parameters:

loader -

metaData -

referenceId -

cache - It's the persister job to assign the cache with a created object, right after its creation, as if in case of circular references those references are respected.

input -

substitution -

Returns:

Throws:

IOException

canPersist

boolean canPersist(Object obj)

Ask the persister if the persister can handle this object
