Overview

An Atom is a thin wrapper around javascript.

The wrapped script can return a value or be a statement. The Atom can supply positional arguments to pass to the wrapped script. The Atom knows how to transform the result of the evaluation of the script into a higher level object.

Summary

Methods
public java.util.List<java.lang.Object>getArguments(ElementReference elementContext)

Creates a list of arguments to pass to the script.

public java.lang.StringgetScript()

Provides the script to be evaluated.

public java.lang.Objecttransform(Evaluation evaluation)

Converts an Evaluation into another more suitable type.

Methods

public java.lang.String getScript()

Provides the script to be evaluated.

Creates a list of arguments to pass to the script.

Parameters:
