Get dynamic property name in execute script

[#1]

Hi,

I am trying to make a Javascript code for the executeScript processor and I wonder if it's possible to get the name of a custom property added from the executeSript Properties tab.

I know that if I add a property "myProperty", I can access it from the script by using myProperty.getValue() (or with .evaluateAttributeExpressions() when needed).

But is it possible to find the key "myProperty" from inside the script ?

I would like to do something like

for(i = 0 ; i < customProperties.length ; i++){
	propertyName = customProperties[i].getName()
	value = propertyName.getValue()
	//Do something with propertyName and its value
}

Thanks in advance !

If anyone needs it (Matt answers helped me a lot but is not exactly correct) :

for(var prop in context.properties) {
  if(prop.isDynamic()) {
	var name = prop.getName();
	var value = context.getProperty(name).evaluateAttributeExpressions(flowFile).getValue();
	//or var value = context.getProperty(name).getValue(); if AttributeExpression are not needed
	log.info('name : ' + name + " value : " + value);
  }
}
