Method Detail

getReflectableClassesImpl

public java.lang.Class[] getReflectableClassesImpl()

Description copied from class: BaseReflector

Implementation of Reflector.getReflectableClasses().

Specified by:

getReflectableClassesImpl in class BaseReflector

getPropertyNamesImpl

protected java.lang.String[] getPropertyNamesImpl(java.lang.Object bean)
                                           throws java.lang.Exception

Description copied from class: BaseBeanReflector

Template method must be overridden. Implementation of BeanReflector.getPropertyNames(Object). Implementation automatically provided for IndexedContainerReflectors. For other reflectors, throws an UnsupportedOperationException.

Specified by:

getPropertyNamesImpl in class BaseBeanReflector

Throws:

java.lang.Exception

getTypeImpl

protected java.lang.Class getTypeImpl(java.lang.Object bean,
                                      java.lang.String propertyName)
                               throws java.lang.Exception

Description copied from class: BaseBeanReflector

Template method must be overridden. Implementation of BeanReflector.getType(Object, String). Default implementation provided. For IndexedContainerReflectors, returns the type by calling ContainerReflector.getContainedType(Class). For other reflectors, checks the type of the property by calling BaseReflector.get(Object, String).

Specified by:

getTypeImpl in class BaseBeanReflector

Throws:

java.lang.Exception

isReadableImpl

protected boolean isReadableImpl(java.lang.Object bean,
                                 java.lang.String propertyName)
                          throws java.lang.Exception

Returns true because all properties of a context are considered readable. If the property isn't a defined property returned by getPropertyNames, null is returned when the BeanReflector.get(Object, String) method is called.

Overrides:

isReadableImpl in class BaseReflector

Throws:

java.lang.Exception

isWriteableImpl

protected boolean isWriteableImpl(java.lang.Object bean,
                                  java.lang.String propertyName)
                           throws java.lang.Exception

Returns true because all properties in a context are assumed to be writeable. If they're not (e.g. - on an Object has been exposed as a Context), an exception is thrown when the set method is called on the context.

Overrides:

isWriteableImpl in class BaseReflector

Throws:

java.lang.Exception

getImpl

protected java.lang.Object getImpl(java.lang.Object bean,
                                   java.lang.String propertyName)
                            throws java.lang.Exception

Description copied from class: BaseBeanReflector

Template method must be overridden. Implementation of BeanReflector.get(Object, String). Implementation automatically provided for IndexedContainerReflectors. For other reflectors, throws an UnsupportedOperationException.

Specified by:

getImpl in class BaseBeanReflector

Throws:

java.lang.Exception

setImpl

protected void setImpl(java.lang.Object bean,
                       java.lang.String propertyName,
                       java.lang.Object value)
                throws java.lang.Exception

Description copied from class: BaseBeanReflector

Template method must be overridden. Implementation of BeanReflector.set(Object, String, Object). Implementation automatically provided for MutableIndexedContainerReflectors. For other reflectors, throws an UnsupportedOperationException.

Specified by:

setImpl in class BaseBeanReflector

Throws:

java.lang.Exception

newInstanceImpl

protected java.lang.Object newInstanceImpl(java.lang.Class clazz,
                                           java.lang.Object parameters)
                                    throws java.lang.Exception

Description copied from class: BaseReflector

Implementation of InstantiatingReflector.newInstance(Class, Object). Default implementation returns a new instance of the given class by calling Class#newInstance()).

Overrides:

newInstanceImpl in class BaseReflector

Throws:

java.lang.Exception
