Keegan Witt updated GROOVY-7522:
--------------------------------
Description:
{{@TupleConstructor}} should not overwrite existing empty default constructors.
For example, this should work, but doesn't currently
{code:java}
assert new Cat("Mr. Bigglesworth").name == null // fails
@groovy.transform.TupleConstructor
class Cat {
String name
int age
Cat(String name) {}
}
{code}
Granted, this is an edge case. But unexpected behavior, nonetheless.
was:
Document that if you have a default constructor with no content,
{{TupleConstructor}} will overwrite the content.
----
Jira was originally titled _TupleConstructor shouldn't overwrite existing
constructors_, but was re-purposed for the reasons mentioned in the comments.
Original content is below.
{{@TupleConstructor}} should not overwrite existing constructors. For example,
this should work, but doesn't currently
{code:java}
assert new Cat("Mr. Bigglesworth").name == null // fails
@groovy.transform.TupleConstructor
class Cat {
String name
int age
Cat(String name) {}
}
{code}
Why aren't the {{includes}}/{{excludes}} annotation elements a sufficient
workaround? Because one might want all the other combinations
{{@TupleConstructor}} provides, but still have their own implementation for a
subset of the combinations.
Issue Type: Bug (was: Documentation)
Summary: TupleConstructor overwrites empty default constructors (was:
Document TupleConstructor overwrites empty default constructors)
