Class BeanInitializer<P>

Object

BeanInitializer<P>

Type Parameters:

P - init-param type

public class BeanInitializer<P>
extends Object

Tries to initialize a bean and it's children with particular parameters, if possible.

If the passed parameters are not directly suitable for initialization, other parameters may also be derived and used instead.

Specifically, two types of properties will be initialized:

• Properties that have identical property-type to P (the current parameters).
• Properties with another property-type that can be extracted from P (the current parameters).

Constructor Summary

Constructors

Constructor and Description
BeanInitializer(Class<?> initializationType) Simpler case where only the current-parameters can be initialized, but for no further property-types.
BeanInitializer(Class<?> initializationType, List<ExtractDerivedParameter<P,?>> extractersToAdd) More complex-case where both current-parameters and other extracted property-types can be initialized.

Method Summary

Modifier and Type	Method and Description
boolean	applyInitializationIfPossibleTo(Object bean, Object parent, Logger logger) Applies the initialization to a bean if possible.
Class<?>	getInitializationType() Type of parameters to be propagated, corresponding to P.
void	setParam(P param) Sets the current parameters used for propagation.

Constructor Detail

BeanInitializer

public BeanInitializer(Class<?> initializationType)

Simpler case where only the current-parameters can be initialized, but for no further property-types.

Parameters:

initializationType - type of parameters to be propagated, corresponding to <P>.

BeanInitializer

public BeanInitializer(Class<?> initializationType,
                       List<ExtractDerivedParameter<P,?>> extractersToAdd)

More complex-case where both current-parameters and other extracted property-types can be initialized.

Parameters:

initializationType - type of parameters to be propagated, corresponding to <P>.

extractersToAdd - extracters to used for other property-types that can be derived from current property-type.

Method Detail

setParam

public void setParam(P param)

Sets the current parameters used for propagation.

Parameters:

param - the parameters to be assigned, and to be propagated into initialized beans.

applyInitializationIfPossibleTo

public boolean applyInitializationIfPossibleTo(Object bean,
                                               Object parent,
                                               Logger logger)
                                        throws InitializeException

Applies the initialization to a bean if possible.

As a prerequisite, setParam(Object) must be called before calling this method.

Initialization is possible if either the parameters set above, or derived parameters are of acceptable type.

Parameters:

bean - the bean to be initialized.

parent - the parent bean of bean.

logger - logger for any errors.

Returns:

true if some kind of initialization occurred with this property, false otherwise.

Throws:

InitializeException - if initialization could not successfully complete.

getInitializationType

public Class<?> getInitializationType()

Type of parameters to be propagated, corresponding to P.
