Graeme Rocher created GROOVY-7970:
-------------------------------------
Summary: Can't call private method from outer class when using
inner classes and @CS
Key: GROOVY-7970
URL: https://issues.apache.org/jira/browse/GROOVY-7970
Project: Groovy
Issue Type: Bug
Reporter: Graeme Rocher
This example:
{code}
import groovy.json.*
import groovy.transform.*
@CompileStatic
class Bar {
private Writable renderTemplate(Object o, Map args) {
}
def foo(Map map, Map arguments) {
def writable = new Writable() {
@Override
Writer writeTo(Writer out) throws IOException {
StreamingJsonBuilder builder = new StreamingJsonBuilder(out)
builder.call {
for(key in map.keySet()) {
def o = map.get(key)
Writable writable = renderTemplate((Object)o, arguments)
call(key.toString(), writable)
}
}
return out
}
}
}
}
writable = new Bar().foo([one:'two'],[foo:'bar'])
sw = new StringWriter()
writable.writeTo(sw)
println sw
{code}
Results in a compilation error:
{code}
[Static type checking] - Cannot find matching method
Bar$1#renderTemplate(java.lang.Object, java.util.Map). Please check if the
declared type is right and if the method exists.
at line: 18, column: 45
{code}
If you attempt to use {{Bar.this}}:
{code}
Writable writable = Bar.this.renderTemplate((Object)o, arguments)
{code}
The result is a VerifierError
{code}
java.lang.VerifyError: (class: Bar$1$_writeTo_closure1, method: doCall
signature: (Ljava/lang/Object;)Ljava/lang/Object;) Incompatible argument to
function
