[jira] [Updated] (GROOVY-8999) Access to private fields and methods
from subclass exhibits strange behavior
[ https://issues.apache.org/jira/browse/GROOVY-8999?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Eric Milles updated GROOVY-8999:
--------------------------------
Description:
This is probably just a slice of GROOVY-1591, GROOVY-3010, GROOVY-3142, GROOVY-5438, et al. Adding {{super.}} qualifier causes strange behaviors. Please consider the following:
{code:java}
class Foo {
private String field = 'field'
private String method() { 'method' }
}
class Bar extends Foo {
void meth() {
field // MissingPropertyException: No such property: field for class: Bar
method() // MissingMethodException: No signature of method: Bar.method()
this.field // MissingPropertyException: No such property: field for class: Bar
this.method() // MissingMethodException: No signature of method: Bar.method()
// so far, so good -- although Groovy allows access to private fields and methods from outside of Bar and Foo
super.field // MissingMethodException: No signature of method: Bar.getField() -- that's strange
super.method() // returns "method" -- Why is this okay?
super.@field // // MissingMethodException: No signature of method: Bar.getField() -- that's strange
super.&method // returns null -- If super.method() works, why does this not return the method reference?
}
}
{code}
