Class AbstractReentrantDeserializationHandler

java.lang.Object

com.inductiveautomation.ignition.common.xmlserialization.deserialization.AbstractDeserializationHandler

com.inductiveautomation.ignition.common.xmlserialization.deserialization.AbstractReentrantDeserializationHandler

All Implemented Interfaces:

DeserializationHandler

Direct Known Subclasses:

AbstractBodyDecoderHandler, AssociatedDataHandler, BooleanHandler, EnumHandler, IgPathHandler, QualifiedPathHandler, TagPathHandler

public abstract class AbstractReentrantDeserializationHandler
extends AbstractDeserializationHandler

This is a specialization of AbstractDeserializationHandler built for handlers that return false from DeserializationHandler.supportsNestedElements() and are designed to be re-entrant (do not store any state).

It stores the object and the reference ID as thread locals to support multi-threaded access.

AbstractReentrantDeserializationHandler

public AbstractReentrantDeserializationHandler()

Method Detail

getObject

public java.lang.Object getObject()

Description copied from interface: DeserializationHandler

Returns the most recent object that this handler created. Note that a handler needs to have this function return its object as early as possible, not just after endElement() has been called. This is used for populating the reference map.

Specified by:

getObject in interface DeserializationHandler

Overrides:

getObject in class AbstractDeserializationHandler

setObject

protected void setObject(java.lang.Object value)

Overrides:

setObject in class AbstractDeserializationHandler

getRefId

public int getRefId()

Description copied from interface: DeserializationHandler

Returns the reference id that was in the start of this element, or -1 if there was none

Specified by:

getRefId in interface DeserializationHandler

Overrides:

getRefId in class AbstractDeserializationHandler

setRefId

public void setRefId(int id)

Description copied from interface: DeserializationHandler

Sets the ref-id that was found at the start of this element, if any.

Specified by:

setRefId in interface DeserializationHandler

Overrides:

setRefId in class AbstractDeserializationHandler
