Class BeanWrapperContext

java.lang.Object

net.sf.juffrou.util.reflect.BeanWrapperContext

public class BeanWrapperContext
extends Object

Holds metadata and preferences for a BeanWrapper.

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.

Method Detail

getNestedContext

public BeanWrapperContext getNestedContext(String thisProperty)

Obtains the BeanWrapperContext that corresponds to the bean type of this property type.

Parameters:

thisProperty - property name in this bean wrapper context (bean class). It must be of bean type.

Returns:

getBeanFieldHandler

public BeanFieldHandler getBeanFieldHandler(String propertyName)

getType

public Type getType(String propertyName)

Gets the type of a property in the wrapped bean. If that property references another bean (a nested bean) Its property types can also be obtained by specifying a property path.
For example getType("pro1.prop2") will get the type of prop2 from the nested bean referenced by prop1.
For each nested bean referenced in this manner, a nested bean wrapper is automatically created. In the previous example, a bean wrapper would be created for the bean referenced by property prop1.

Parameters:

propertyName -

Returns:

getBeanClass

public Class<?> getBeanClass()

Get the wrapped bean class

Returns:

newBeanInstance

public Object newBeanInstance()

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 -
