---|---|
protected String |
m_sMethod The name of the method to invoke. |
Constructor Summary | |
---|---|
ReflectionUpdater() Default constructor (necessary for the ExternalizableLite interface). |
|
ReflectionUpdater(String sMethod) Construct a ReflectionUpdater for a given method name. |
Method Summary | |
---|---|
boolean |
equals(Object o) Compare the ReflectionUpdater with another object to determine equality. |
String |
getMethodName() Determine the name of the method that this extractor is configured to invoke. |
int |
hashCode() Determine a hash value for the ReflectionUpdater object according to the general Object.hashCode() contract. |
void |
readExternal(DataInput in) Restore the contents of this object by loading the object's state from the passed DataInput object. |
void |
readExternal(PofReader in) Restore the contents of a user type instance by reading its state using the specified PofReader object. |
String |
toString() Provide a human-readable description of this ValueUpdater object. |
void |
update(Object oTarget, Object oValue) Update the state of the passed target object using the passed value. For intrinsic types, the specified value is expected to be a standard wrapper type in the same manner that reflection works; for example, an int value would be passed as a java.lang.Integer. |
void |
writeExternal(DataOutput out) Save the contents of this object by storing the object's state into the passed DataOutput object. |
void |
writeExternal(PofWriter out) Save the contents of a POF user type instance by writing its state using the specified PofWriter object. |
