Field Detail

delegate

private final java.lang.Object delegate

The DMO which will handle unimplemented calls of the proxy object.

dtoClass

private final java.lang.Class<?> dtoClass

The class representing abstract DTO class

dtoObject

private java.lang.Object dtoObject

The object created from DTO abstract class and DMO instance

Constructor Detail

DtoInvocationHandler

public DtoInvocationHandler(java.lang.Object delegate,
                            java.lang.Class<?> dtoClass)

The constructor. Saves the delegate as a constant member.

Parameters:

delegate - The delegate DMO.

dtoClass - The object created from DTO abstract class and DMO instance

Method Detail

invoke

public java.lang.Object invoke(java.lang.Object proxy,
                               java.lang.reflect.Method method,
                               java.lang.Object[] args)
                        throws java.lang.Throwable

Processes a method invocation on a proxy instance and returns the result. This method will be invoked on an invocation handler when a method is invoked on a proxy instance that it is associated with.

Specified by:

invoke in interface java.lang.reflect.InvocationHandler

Parameters:

proxy - the proxy instance that the method was invoked on.

method - the Method instance corresponding to the interface method invoked on the proxy instance. The proxy is constructed so that this method should be relayed to the delegate instead.

args - an array of objects containing the values of the arguments passed in the method invocation on the proxy instance, or null if interface method takes no arguments.

Returns:

the value obtained from invocation of the method on DMO, if any.

Throws:

java.lang.Throwable - the exception to throw from the method invocation on the DMO instance.

getPropertyValues

public java.util.Map<java.lang.String,java.lang.Object> getPropertyValues()

Get all the properties of this compound object by collecting all properties of the nested object, an instance of dmo interface and the created proxy object, an instance of the dto abstract class.

Specified by:

getPropertyValues in interface PropertiesDescriptor

Returns:

The map of properties to their values.

setProxiedObject

public void setProxiedObject(java.lang.Object dtoObject)

Set the reference to the object created from DTO abstract class and DMO instance

Parameters:

dtoObject - The object created from DTO abstract class and DMO instance

setProperties

private static void setProperties(java.util.Map<java.lang.String,java.lang.Object> valuesMap,
                                  java.lang.Object obj,
                                  java.lang.Class<?> objClass)

Fills the given properties map by expecting the target object properties implemented by the given type.

Parameters:

valuesMap - The given properties map

obj - The target object

objClass - The given type
