Class Composite.Injector

org.simpleframework.xml.core.Composite.Injector

Enclosing class:

Composite

private class Composite.Injector
extends Composite.Builder

This takes the approach that the objects are deserialized first then the instance is created using a constructor. In order for the best constructor to be found all the potential objects need to be deserialized first, then based on what has been deserialized a constructor is chosen and the parameters are injected in to it.

Constructor Details

Injector

private Injector(Composite composite,
 Criteria criteria,
 Schema schema,
 Instance value)

Constructor for the Injector object. This creates a builder object capable of instantiating a object using a constructor. It injects the constructor parameters in to the constructor by using the deserialized objects.

Parameters:

composite - this is the composite object used by this

criteria - this collects the objects being deserialized

schema - this is the class schema used by this

value - this is the instance created by the strategy

Method Details

read

public Object read(InputNode node)
            throws Exception

This read method performs deserialization of the XML schema class type by traversing the contacts and using details from the provided XML element. Here an instance is instantiated only after everything has been deserialized so that the instances can be injected in to a constructor.

Overrides:

read in class Composite.Builder

Parameters:

node - the XML element that will be deserialized by this

Returns:

this returns the fully deserialized object graph

Throws:

Exception

readInject

private Object readInject(InputNode node)
                   throws Exception

This readInject method performs deserialization of the XML schema class type by traversing the contacts and creating them using details from the provided XML element. Because this will convert a non-primitive value it delegates to other converters to perform deserialization of lists and primitives.

This takes the approach of reading the elements and attributes before instantiating the object. Instantiation is performed using a declared constructor. The parameters are taken from the deserialized objects.

Parameters:

node - the XML element that will be deserialized by this

Returns:

this returns the fully deserialized object graph

Throws:

Exception
