Class ConstructedBeanHandler

java.lang.Object
  org.progeeks.util.xml.AbstractObjectHandler
      org.progeeks.util.xml.BeanObjectHandler
          org.progeeks.util.xml.BeanConfiguratorHandler
              org.progeeks.util.xml.ConstructedBeanHandler

All Implemented Interfaces:

ObjectHandler

public class ConstructedBeanHandler
extends BeanConfiguratorHandler

Object handler that uses BeanConfigurators to delay the creation of objects until a list of constructor arguments can be collected. Example XML: <construct-org.progeeks.meta.ListPropertyType> <ctor.arguments> <org.progeeks.meta.ClassPropertyType _ctor="java.lang.String" /> </ctor.arguments> </construct-org.progeeks.meta.ListPropertyType>

Method Summary

boolean	canHandle(java.lang.String tag) Returns true if this handler applies to the specified object tag.
java.lang.Object	createObject(java.lang.String tag, org.xml.sax.Attributes atts, ObjectXmlReader reader) Creates and returns an object based on the specified parameters.
java.lang.Class	getPropertyClass(java.lang.Object obj, java.lang.String field, ObjectXmlReader reader) Overridden to attempt to do a better type lookup when possible.
protected java.lang.String	getUnprefixedName(java.lang.String tag) Returns the class name part of a tag (without the prefix) or null if the tag does not contain a prefix.
java.lang.Object	resolveObject(java.lang.String tag, java.lang.Object obj, ObjectXmlReader reader) Used the bean configurator to create the actual object with a set of constructor arguments.

Method Detail

getUnprefixedName

protected java.lang.String getUnprefixedName(java.lang.String tag)

Returns the class name part of a tag (without the prefix) or null if the tag does not contain a prefix.

Overrides:

getUnprefixedName in class BeanConfiguratorHandler

canHandle

public boolean canHandle(java.lang.String tag)

Returns true if this handler applies to the specified object tag.

Specified by:

canHandle in interface ObjectHandler

Overrides:

canHandle in class BeanConfiguratorHandler

getPropertyClass

public java.lang.Class getPropertyClass(java.lang.Object obj,
                                        java.lang.String field,
                                        ObjectXmlReader reader)

Overridden to attempt to do a better type lookup when possible. If we're operating on a configurator that actually has its class initialized then we should be able to determine type information at this time... at least in most cases.

Specified by:

getPropertyClass in interface ObjectHandler

Overrides:

getPropertyClass in class BeanConfiguratorHandler

createObject

public java.lang.Object createObject(java.lang.String tag,
                                     org.xml.sax.Attributes atts,
                                     ObjectXmlReader reader)

Creates and returns an object based on the specified parameters.

Specified by:

createObject in interface ObjectHandler

Overrides:

createObject in class BeanConfiguratorHandler

resolveObject

public java.lang.Object resolveObject(java.lang.String tag,
                                      java.lang.Object obj,
                                      ObjectXmlReader reader)

Used the bean configurator to create the actual object with a set of constructor arguments.

Specified by:

resolveObject in interface ObjectHandler

Overrides:

resolveObject in class AbstractObjectHandler
