[jira] [Updated] (GROOVY-8190) CompileStatic cant infer type when
using map as map key
[ https://issues.apache.org/jira/browse/GROOVY-8190?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Richard Zhang updated GROOVY-8190:
----------------------------------
Description:
open groovy console, paste code below
{code:groovy}
import groovy.transform.*
@CompileStatic
void foo(Map<Map<String, String>, List<Map<String, Object>>> map){
for(Map<String, String> key : map.keySet()) {
def x = map[key]
def y = x[0][""]
}
}
{code}
and you will see it fails to compile
{code}
> import groovy.transform.*
@CompileStatic
void foo(Map<Map<String, String>, List<Map<String, Object>>> map){
for(Map<String, String> key : map.keySet()) {
def x = map[key]
def y = x[0][""]
}
}
Result: org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
ideaGroovyConsole.groovy: 7: [Static type checking] - Cannot find matching method java.lang.Object#getAt(int). Please check if the declared type is right and if the method exists.
@ line 7, column 17.
def y = x[0][""]
