[jira] [Updated] (GROOVY-8320) Support property references in addition to the method references from Java 8

["David Kron (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/GROOVY-8320?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

David Kron updated GROOVY-8320:
-------------------------------
    Description: 
It would be great if the method reference syntax from Java (Class::method or obj::method) could also be extended to support Groovy properties. The new parser currently already parses the syntax without error, but it gets treated as a method reference.

Potential example usage:
{code:java}
class Test {
    String property
}

def test = new Test(property: 'Hello')
def boundReference = test::property
def unboundReference = Test::property

// getting/setting property using bound reference
println boundReference.get()
boundReference.set('Hello to you!')

// getting/setting property using unbound reference
println unboundReference.get(test)
unboundReference.set(test, 'Hello to you!')

// retrieving meta information
println boundReference.type
println boundReference.name
println boundReference.target

{code}
