Iurii created GROOVY-8138:
-----------------------------
Summary: Compile static to support streams
Key: GROOVY-8138
URL: https://issues.apache.org/jira/browse/GROOVY-8138
Project: Groovy
Issue Type: New Feature
Components: Static compilation
Affects Versions: 2.4.10
Environment: Windows 7, JDK 1.8.0_66
Reporter: Iurii
The following code
{code}
import groovy.transform.CompileStatic
import static java.util.stream.Collectors.toList
@CompileStatic
class Test {
static void main(String[] args) {
List<String> tables = ['a', 'b']
println tables.stream().filter { tableName -> tableName.contains('a')
}.collect(toList())
}
}
{code}
fails with the error:
Error:(9, 55) Groovyc: [Static type checking] - Cannot find matching method
java.lang.Object#contains(java.lang.String). Please check if the declared type
is right and if the method exists.
But works fine with compile dynamic.
It would be great if CompileStatic get all required types from the steam (type
info should be there, Java can handle similar code)
