--------------------------------------
Summary: Provide a BeanIntrospector implementation which supports
properties in a fluent API
Key: BEANUTILS-428
URL: https://issues.apache.org/jira/browse/BEANUTILS-428
Project: Commons BeanUtils
Issue Type: Improvement
Components: Bean / Property Utils
Affects Versions: 1.8.3
Reporter: Oliver Heger
Assignee: Oliver Heger
BEANUTILS-425 was about adding a mechanism for customizing bean introspection.
This ticket is a request for a concrete new {{BeanIntrospector}} implementation
which detects writable bean properties even if the return value of the set
method is not *void*.
The _builder_ pattern and fluent API definitions become more and more popular.
Here methods are offered for setting properties that return the current
instance of a builder object for method chaining, for instance:
{code}
public class FooBuilder {
public FooBuilder setFooProperty1(String value) {
...
return this;
}
public FooBuilder setFooProperty2(int value) {
...
return this;
}
}
{code}
Standard bean introspection will not recognize set methods like that because
they do not conform to the Java Beans specification. A new {{BeanIntrospector}}
implementation can be created which ignores the return type of set methods and
create corresponding {{PropertyDescriptor}} objects with a correct write method.
