Eric Milles resolved GROOVY-7274.
---------------------------------
Fix Version/s: 4.0.0-alpha-3
Resolution: Fixed
> Improve type inference for hash map -> Map<?, ?>
> ------------------------------------------------
>
> Key: GROOVY-7274
> URL: https://issues.apache.org/jira/browse/GROOVY-7274
> Project: Groovy
> Issue Type: Improvement
> Components: Static compilation
> Affects Versions: 2.4.0
> Reporter: Hendy Irawan
> Assignee: Eric Milles
> Priority: Trivial
> Fix For: 4.0.0-alpha-3
>
>
> Currently we have to do this:
> {code}
> @CompileStatic
> ...
> inserter.createNode([v: it.value, l: it.language] as Map<String, Object>,
> labelLabel)
> {code}
> If not we'll get:
> {code}
> Error:(81, 37) Groovyc: [Static type checking] - Cannot call
> org.neo4j.unsafe.batchinsert.BatchInserter#createNode(java.util.Map
> <java.lang.String, java.lang.Object>, org.neo4j.graphdb.Label[]) with
> arguments [java.util.LinkedHashMap <java.lang.String, java.lang.String>,
> org.neo4j.graphdb.Label]
> {code}
> But since the caller requests Map<String, Object>, Groovy can create the
> hashmap as <String, Object> instead of <String, String>... saving us from
> explicit type coercion even with {{@CompileStatic}}. (similar to Java7's
> diamond operator)
