public CompositeUpdater()
public CompositeUpdater(ValueExtractor extractor, ValueUpdater updater)
Note: the extractor and updater here are not symmetrical in nature: the extractor is used to "drill-down" to the target object, while the updater will operate on that extracted object.
extractor
- the ValueExtractorupdater
- the ValueUpdaterpublic CompositeUpdater(java.lang.String sName)
For example: "getAddress.setZip" method name will indicate that the "getAddress()" method should be used to extract an Address object, which will then be used by the "setZip(String)" call.
sName
- a dot-delimited sequence of N method names which results in a CompositeUpdater that is based on an chain of (N-1) ReflectionExtractor
objects and a single ReflectionUpdater
