java.lang.Object

net.sf.juffrou.util.reflect.BeanWrapperContext

public class BeanWrapperContext
extends Object

Performs introspection and holds metadata information about a class used by the BeanWrapper.
If you have to create several BeanWrappers for the same java class, use this and save the introspection overhead.
This class is thread safe.

Methods

Modifier and Type	Method and Description
Class<?>	getBeanClass() Get the wrapped bean class
BeanContextCreator<? extends BeanWrapperContext>	getBeanContextCreator()
BeanFieldHandler	getBeanFieldHandler(String propertyName)
Map<String,BeanFieldHandler>	getFields()
Map<String,BeanWrapper>	getNestedWrappers() Returns all the nested bean wrappers that have been created inside this bean wrapper. Nested bean wrappers are created when you access a nested property (i.e.
Map<TypeVariable<?>,Type>	getTypeArgumentsMap()
boolean	isEagerInstatiation()
Object	newBeanInstance()
void	setBeanContextCreator(BeanContextCreator<? extends BeanWrapperContext> beanContextCreator)
void	setBeanInstanceCreator(BeanInstanceCreator beanInstanceCreator) The bean wrapper creates new instances using Class.newIntance().
void	setEagerInstatiation(boolean eager) Defines when a new instance is created. If eager is true, a new instance is created when the BeanWrapper is created and reset.

Method Detail

getBeanFieldHandler

public BeanFieldHandler getBeanFieldHandler(String propertyName)

getBeanClass

public Class<?> getBeanClass()

Get the wrapped bean class

Returns:

newBeanInstance

public Object newBeanInstance()

getNestedWrappers

public Map<String,BeanWrapper> getNestedWrappers()

Returns all the nested bean wrappers that have been created inside this bean wrapper.
Nested bean wrappers are created when you access a nested property (i.e. getValue("prop1.prop2"))

Returns:

a Map where the keys are property names and the values are bean wrappers

getFields

public Map<String,BeanFieldHandler> getFields()

getTypeArgumentsMap

public Map<TypeVariable<?>,Type> getTypeArgumentsMap()

setBeanInstanceCreator

public void setBeanInstanceCreator(BeanInstanceCreator beanInstanceCreator)

The bean wrapper creates new instances using Class.newIntance(). You can use this this if you want to create class instances yourself.

Parameters:

beanInstanceCreator -

getBeanContextCreator

public BeanContextCreator<? extends BeanWrapperContext> getBeanContextCreator()

setBeanContextCreator

public void setBeanContextCreator(BeanContextCreator<? extends BeanWrapperContext> beanContextCreator)

isEagerInstatiation

public boolean isEagerInstatiation()

setEagerInstatiation

public void setEagerInstatiation(boolean eager)

Defines when a new instance is created.
If eager is true, a new instance is created when the BeanWrapper is created and reset. If eager is false, a new instance will only be created when setting a property value.
Default is false.

Parameters:

eagerInstatiation -
