org.eclipse.persistence.internal.descriptors.DescriptorIterator

org.eclipse.persistence.internal.sessions.remote.ReplaceValueHoldersIterator

public class ReplaceValueHoldersIterator
extends DescriptorIterator

Helper class for RemoteSessionController. This descriptor iterator will replace all the normal value holders in an object with remote value holders that can be serialized to the client.

Constructor Details

ReplaceValueHoldersIterator

public ReplaceValueHoldersIterator(RemoteSessionController controller)

public constructor

Method Details

buildObjectDescriptor

protected ObjectDescriptor buildObjectDescriptor(Object object)

build and return an object descriptor for the specified object

buildRemoteValueHolderFor

protected RemoteValueHolder buildRemoteValueHolderFor(ValueHolderInterface valueHolder)

build a properly initialized remote value holder

initialize

protected void initialize(RemoteSessionController controller)

initialize instance

internalIterateIndirectContainer

protected void internalIterateIndirectContainer(IndirectContainer container)

Iterate an indirect container.

Overrides:

internalIterateIndirectContainer in class DescriptorIterator

internalIterateValueHolder

protected void internalIterateValueHolder(ValueHolderInterface originalValueHolder)

Synchronously create a remote value holder. The value holder passed in is ignored so that we can ensure that the value holder being held by the object is used instead of the one that was passed in.

Overrides:

internalIterateValueHolder in class DescriptorIterator

iterate

protected void iterate(Object object)

if we get here, it is a domain object

Specified by:

iterate in class DescriptorIterator

saveRemoteValueHolder

protected void saveRemoteValueHolder(RemoteValueHolder remoteValueHolder)

save the remote value holder for later use

setOneToOneMappingSettingsIn

protected void setOneToOneMappingSettingsIn(RemoteValueHolder remoteValueHolder)

Set one-to-one mapping information. This allows us to look for a cache hit before going to the database.
