#include <coherence/util/extractor/ReflectionUpdater.hpp>
Inherits Object, ValueUpdater, and PortableObject.
Inherited by TypedUpdater, and TypedUpdater< AH::ValueType::BoxedType, C, M, coherence::lang::BoxHandle< AH::ValueType >, OH >.
Local execution of a ReflectionUpdater is dependent upon target class and method having been registered with the SystemClassLoader. For cases where the registration has not been performed or is not possible locally executable C++ updaters may either be custom built, or auto-generated using the TypedUpdater<>.

Public Member Functions | ||||||||||||||||
virtual void | update (Object::Handle hTarget, Object::Holder ohValue) const | |||||||||||||||
Update the state of the passed target object using the passed value.

virtual void | readExternal (PofReader::Handle hIn) | |||||||||||||||
virtual void | writeExternal (PofWriter::Handle hOut) const | |||||||||||||||
virtual bool | equals (Object::View v) const | |||||||||||||||
virtual size32_t | hashCode () const | |||||||||||||||
Return a hash code value for the Object. This method is supported for the benefit of hash-based containers.
The general contract of
The default implementation is identity based.
| ||||||||||||||||
virtual TypedHandle < const String > | toString () const | |||||||||||||||
Output a human-readable description of this Object to the given stream. Note that when overriding this method the return type must be TypedHandle<const String> rather then String::View. These two types are assignment compatible but not equivalent and declaring the override with String::View will not be a compatible override. coherence::lang::operator<<(std::ostream, Object::View) is defined and will call into the toString method, to output Objects. If a managed String object is desired, the COH_TO_STRING macro can be used to build up a String from streamable contents and is generally how toString() will be implemented.
Object::View vKey = ... Object::View vValue = ... std::cout << vKey << " = " << vValue << std::endl; String::View vs = COH_TO_STRING(vKey << " = " << vValue); The COH_TO_STRING macro is also the most common way to implement the toString method. For example:
virtual TypedHandle<const String> Person::toString() const { return COH_TO_STRING("Name: " << f_sName << " SSN: " << f_nSSN); }

ReflectionUpdater | ( | String::View | vsMethod | ) | [protected] |
Construct a ReflectionUpdater for a given method name.
This implementation assumes that the corresponding classes will have one and only one method with a specified name and this method will have exactly one parameter.
virtual String::View getMethodName | ( | ) | const [virtual] |
Determine the name of the method that this extractor is configured to invoke.
