An annotation on a constructor that shows how the parameters of that constructor correspond to the constructed object's getter methods. For example:
public class MemoryUsage { // standard JavaBean conventions with getters @ConstructorParameters({"init", "used", "committed", "max"}) public MemoryUsage(long init, long used, long committed, long max) {...} public long getInit() {...} public long getUsed() {...} public long getCommitted() {...} public long getMax() {...} }
The annotation shows that the first parameter of the constructor
can be retrieved with the getInit()
method, the second one with
the getUsed()
method, and so on. Since parameter names are not in
general available at runtime, without the annotation there would be
no way of knowing which parameter corresponds to which property.
If a constructor is annotated by the both @java.beans.ConstructorProperties
and @javax.management.ConstructorParameters
annotations
the JMX introspection will give an absolute precedence to the latter one.
