VelocityContextReflector

public VelocityContextReflector()
Method Detail

getReflectableClassesImpl

protected java.lang.Class[] getReflectableClassesImpl()
                                               throws java.lang.Exception
Implementation of Reflector.getReflectableClasses().

Specified by:
getReflectableClassesImpl in class BaseReflector
Throws:
java.lang.Exception

getVelocityContext

protected org.apache.velocity.context.Context getVelocityContext(java.lang.Object bean)
Get a Velocity Context from the specified bean.

Parameters:
bean - expected to be the Context in the default implementation.
Returns:
Context

getPropertyNamesImpl

protected java.lang.String[] getPropertyNamesImpl(java.lang.Object bean)
                                           throws java.lang.Exception
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
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
Implementation of BeanReflector.isReadable(Object, String). Default implementation assumes that all properties of the bean specified by BeanReflector.getPropertyNames(Object) are readable.

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
Implementation of BeanReflector.isWriteable(Object, String). Default implementation assumes that all readable properties are also writeable. One exception to this is when this reflector is an IndexedContainerReflector but not a MutableIndexedContainerReflector, in which case no properties are considered writeable.

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
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
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
