Example 96 with ScriptContext

use of javax.script.ScriptContext in project ofbiz-framework by apache.

the class GroovyUtil method getBinding.

/**
 * Returns a <code>Binding</code> instance initialized with the
 * variables contained in <code>context</code>. If <code>context</code>
 * is <code>null</code>, an empty <code>Binding</code> is returned.
 * <p>The expression is parsed to initiate non existing variable
 * in <code>Binding</code> to null for GroovyShell evaluation.
 * <p>The <code>context Map</code> is added to the <code>Binding</code>
 * as a variable called "context" so that variables can be passed
 * back to the caller. Any variables that are created in the script
 * are lost when the script ends unless they are copied to the
 * "context" <code>Map</code>.</p>
 *
 * @param context A <code>Map</code> containing initial variables
 * @return A <code>Binding</code> instance
