Class BeanWrapperContext

java.lang.Object

net.sf.juffrou.util.reflect.BeanWrapperContext

public class BeanWrapperContext
extends Object

Holds introspection information for a java bean class.

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 BeanWrapperContext and save the introspection overhead.
This class is thread safe.

Constructor Detail

BeanWrapperContext

protected BeanWrapperContext(BeanWrapperFactory factory,
                  Class clazz,
                  Type... types)

Method Detail

create

public static final BeanWrapperContext create(Class clazz)

create

public static final BeanWrapperContext create(Class clazz,
                        Type... types)

getNestedContext

public BeanWrapperContext getNestedContext(String thisProperty,
                                  Object propertyValue)

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()

getFactory

public BeanWrapperFactory getFactory()

getBeanInstanceBuilder

public BeanInstanceBuilder getBeanInstanceBuilder()

setBeanInstanceBuilder

public void setBeanInstanceBuilder(BeanInstanceBuilder beanInstanceBuilder)

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

Parameters:

beanInstanceBuilder -

setBeanContextBuilder

public void setBeanContextBuilder(BeanContextBuilder beanContextBuilder)
