Constructor Detail

PojoDescriptorBuilderImpl

public PojoDescriptorBuilderImpl()

The constructor. By default it only introspects methods that are public and NOT static.
ATTENTION:
You need to AbstractComponent.initialize() this component before it can be used.

PojoDescriptorBuilderImpl

public PojoDescriptorBuilderImpl(MapFactory mapFactory)

The constructor. By default it only introspects methods that are public and NOT static.
ATTENTION:
You need to AbstractComponent.initialize() this component before it can be used.

Parameters:

mapFactory - is the factory used to create the descriptor cache.

Method Detail

doInitialize

protected void doInitialize()

This method performs the actual initialization. It is called when AbstractComponent.initialize() is invoked for the first time.
ATTENTION:
When you override this method from a sub-class you need to do a super.AbstractComponent.doInitialize().

Overrides:

doInitialize in class AbstractLoggableComponent

getMethodIntrospector

protected PojoMethodIntrospector getMethodIntrospector()

This method gets the introspector used to find potential methods for accessing properties of a POJO.

Returns:

the introspector to use.

setMethodIntrospector

@Inject
public void setMethodIntrospector(PojoMethodIntrospector introspector)

This method sets the method-introspector.

Parameters:

introspector - the introspector to set.

getFieldIntrospector

protected PojoFieldIntrospector getFieldIntrospector()

This method gets the introspector used to find potential fields for accessing properties of a POJO.

Returns:

the introspector to use.

setFieldIntrospector

@Inject
public void setFieldIntrospector(PojoFieldIntrospector introspector)

This method sets the field-introspector.

Parameters:

introspector - the introspector to set.

getAccessorBuilders

protected Collection<PojoPropertyAccessorBuilder<?>> getAccessorBuilders()

This method gets the accessor-builders used to create the accessors for properties of a POJO.

Returns:

the accessorBuilders.

getDescriptorEnhancer

public PojoDescriptorEnhancer getDescriptorEnhancer()

This method gets the PojoDescriptorEnhancer to use.

Returns:

the PojoDescriptorEnhancer.

getDependencies

protected ExtendedPojoDescriptorDependenciesImpl getDependencies()

This method gets the ExtendedPojoDescriptorDependenciesImpl.

Specified by:

getDependencies in class AbstractPojoDescriptorBuilder

Returns:

the ExtendedPojoDescriptorDependenciesImpl.

setConfiguration

@Inject
public void setConfiguration(ExtendedPojoDescriptorDependenciesImpl configuration)

This method sets the ExtendedPojoDescriptorDependenciesImpl.

Parameters:

configuration - is the ExtendedPojoDescriptorDependenciesImpl .

registerAccessor

protected boolean registerAccessor(PojoDescriptorImpl<?> descriptor,
                                   PojoPropertyAccessor accessor)

This method registers the given accessor for the given descriptor.

Parameters:

descriptor - is the PojoDescriptor.

accessor - is the PojoPropertyAccessor to register.

Returns:

true if the given accessor has been registered or false if it has been ignored (it is a duplicate).

createDescriptor

protected <P> PojoDescriptorImpl<P> createDescriptor(GenericType<P> pojoType)

This method creates the pojo descriptor for the given pojoType.

Specified by:

createDescriptor in class AbstractPojoDescriptorBuilder

Type Parameters:

P - is the templated type of the pojoType.

Parameters:

pojoType - is the GenericType reflecting the Pojo.

Returns:

the descriptor used to get information about the properties of the according Pojo.

See Also:

PojoDescriptorBuilder.getDescriptor(java.lang.Class)

logDuplicateAccessor

protected void logDuplicateAccessor(PojoPropertyAccessor accessor,
                                    PojoPropertyAccessor duplicate)

This method is called if the accessor given by duplicate was ignored because it has the same name and mode as the given accessor that is already registered. This method does nothing. It may be overridden to do some debug logging.

Parameters:

accessor - is the accessor that is already registered.

duplicate - is the duplicate that has been ignored.
