#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 >.
ReflectionUpdater cannot be executed against local C++ caches, only against remote caches. Locally executable C++ updaters may either be custom built, or auto-generated via 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 | 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 void | toStream (std::ostream &out) const | |||||||||||||||
Output a human-readable description of this Object to the given stream. coherence::lang::operator<<(std::ostream, Object::View) is defined and will call into the toStream 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.
Object::View vKey = ... Object::View vValue = ... std::cout << vKey << " = " << vValue << std::endl; String::Handle hs = COH_TO_STRING(vKey << " = " << vValue);

Protected Member Functions | ||||||||||||||||
ReflectionUpdater () | ||||||||||||||||
Construct an empty ReflectionUpdater (necessary for the PortableObject interface). | ||||||||||||||||
ReflectionUpdater (String::View vsMethod) | ||||||||||||||||

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 void update | ( | Object::Handle | hTarget, | |
Object::Holder | ohValue | |||
) | const [virtual] |
Update the state of the passed target object using the passed value.
hTarget | the Object to update the state of | |
ohValue | the new value to update the state with |
ClassCastException | if this ValueUpdater is incompatible with the passed target object or the value and the implementation requires the passed object or the value to be of a certain type | |
Exception | if this ValueUpdater encounters a checked exception in the course of updating the target object | |
IllegalArgumentException | if this ValueUpdater cannot handle the passed target object or value for any other reason; an implementor should include a descriptive message |
UnsupportedOperationException | always |
Implements ValueUpdater.
Reimplemented in TypedUpdater, and TypedUpdater< AH::ValueType::BoxedType, C, M, coherence::lang::BoxHandle< AH::ValueType >, OH >.
virtual String::View getMethodName | ( | ) | const [virtual] |
Determine the name of the method that this extractor is configured to invoke.
