----------------------------------------
Summary: Inconsistent metaClass capability for .static properties
and methods vs ordinary dynamic properties and methods
Key: GROOVY-10392
URL: https://issues.apache.org/jira/browse/GROOVY-10392
Project: Groovy
Issue Type: Improvement
Components: Compiler
Affects Versions: 4.0.0-beta-2, 3.0.9
Reporter: William Woodman
Fix For: 3.x, 4.x
runtime addition and working with static dynamic properties and methods is
inconsistent and doesnt work the same as the equivalent capability for ordinary
dynamic properties and methods.
I've tried to show the problem in the script code below
package script
class SomeClass {
static String classDeclaredStatName = "in class definition static name"
String name = "instance level name"
}
//add a new property to metaclass - works fine
SomeClass.metaClass.dynProp = "dynamic property added"
SomeClass.metaClass.dynMethod = \{"dynamic method added as closure"}
SomeClass.metaClass.static.dynStaticProp = "dynamic static property added"
SomeClass.metaClass.static.dynStaticMethod = \{"dynamic static method added"}
assert SomeClass.classDeclaredStatName == "in class definition static name"
assert SomeClass.dynStaticMethod() == "dynamic static method added"
//this forces conversion of metaClassImpl to expandoMetaClass
SomeClass myc = new SomeClass()
assert myc.name == "instance level name"
assert myc.classDeclaredStatName == "in class definition static name"
assert myc.dynProp == "dynamic property added"
assert myc.dynMethod() == "dynamic method added as closure"
assert myc.dynStaticMethod() == "dynamic static method added"
def res
res = myc.metaClass.properties //returns list of metaBeanProperty
res = myc.metaClass.getMetaMethods() //works and returns list of metaMethods
//This is the only method for static's in MOP - this works but you have to know
the name of the method in advance
res = myc.metaClass.getStaticMetaMethod("dynStaticMethod", [] as ArrayList)
//these functions are missing from MOP and would enable you to query for static
props/methods
res = myc.metaClass.getStaticMetaMethods() //this method doesnt exist in
MOP api
res = myc.metaClass.getStaticProperties() //this method doesnt exist
in MOP api either
