generating generic method

[glassfishrobot]

Problem is generating a generic method like: public <T> T foo(..)

{..}

The problem is in instantiating a JTypeVar.

Making the constructor public would solve my problem as follows: JTypeVar Ttype = new JTypeVar(codeModel, "T"); JMethod fooMethod = someClass.method(JMod.PRIVATE, Ttype, "foo"); fooMethod.generify("T");

Can you please make the constructor public or introduce some factory method or give me a hint how to generate generic methods, otherwise?

mattbenson said: I have a method:

JType naiveType(String name) { try

{ return codeModel.parseType(name); }

catch (ClassNotFoundException e)

{ return codeModel.directClass(name); }

}

if I, e.g., pass "T" to this method and use the resulting JType as the return value of my method, presumably the directClass() execution path is taken, and the final code output seems to do what I want.

johncarl81 said: It turns out that this is possible with CodeModel as it stands. Here's an example from a post on StackOverflow:

http://stackoverflow.com/q/9355160/654187

final JDefinedClass exampleClass = codeModel._class( "com.example.ExampleClass" ); final JMethod method = exampleClass.method( JMod.PUBLIC, Object.class, "getValue" ); final JTypeVar t = method.generify( "T" ); method.type( t ); method.param( codeModel.ref( Class.class ).narrow( t ), "type" ); method.body()._return(JExpr._null());

produces:

package com.example;

public class ExampleClass {

public<T >T getValue(Class<T> type)

{ return null; }

}

Thanks to ajlane for figuring this one out.
