[SOLVED] How do I dynamically invoke methods in Groovy?

How do I dynamically invoke methods in Groovy?

At runtime I'm grabbing a list of method names on a class, and I want to invoke these methods. I understand how to get the first part done from here: http://docs.codehaus.org/display/GROOVY/JN3535-Reflection

GroovyObject.methods.each{ println it.name }

What I can't seem to find information on is how to then invoke a method once I've grabbed its name.

What I want is to get here:

GroovyObject.methods.each{ GroovyObject.invokeMethod( it.name, argList) }

I can't seem to find the correct syntax. The above seems to assume I've overloaded the default invokeMethod for the GroovyObject class, which is NOT the direction I want to go.

Solution

Groovy allows for dynamic method invocation as well as dynamic arguments using the spread operator:

def dynamicArgs = [1,2]
def groovy = new GroovyObject()
GroovyObject.methods.each{ 
     groovy."$it.name"(staticArg, *dynamicArgs)
}
