How to list all binding variables with GroovyShell - binding

Question

I'm very new to Groovy. How can I list all variables I passed to Binding constructor ?
Considering I have following :
#Test
public void test() {
List<String> outputNames = Arrays.asList("returnValue", "ce");
String script = getScript();
Script compiledScript = compileScript(script);
CustomError ce = new CustomError("shit", Arrays.asList(new Long(1)));
Map<String, Object> inputObjects = new HashMap<String, Object>();
inputObjects.put("input", "Hovada");
inputObjects.put("error", ce);
Binding binding = new Binding(inputObjects);
compiledScript.setBinding(binding);
compiledScript.run();
for (String outputName : outputNames) {
System.out.format("outputName : %s = %s", outputName, binding.getVariable(outputName));
}
}
private Script compileScript(String script) {
GroovyShell groovyShell = new GroovyShell();
Script compiledScript = groovyShell.parse(script);
return compiledScript;
}
How can I iterate over all the variables (over the hashMap) in groovy.script ?

Answer 1

Script compiledScript represents the script, if you look at its source code, you'll see that it has property binding and getter+setter and Binding has a variable "variables". So you go :
binding.variables.each{
println it.key
println it.value
}
For Map<String, String> ...
you can also set properties like this :
Binding binding = new Binding(inputObjects);
compiledScript.setBinding(binding);
compiledScript.setProperty("prop", "value");
compiledScript.run();
and it is stored into the Binding variables.
