Example 51 with SimpleScriptContext

use of javax.script.SimpleScriptContext in project Lucee by lucee.

the class AbstractScriptEngine method getScriptContext.

/**
 * Returns a <code>SimpleScriptContext</code>.  The <code>SimpleScriptContext</code>:

 * <ul>
 * <li>Uses the specified <code>Bindings</code> for its <code>ENGINE_SCOPE</code>
 * </li>
 * <li>Uses the <code>Bindings</code> returned by the abstract <code>getGlobalScope</code>

 * </li>
 * <li>Uses the Reader and Writer in the default <code>ScriptContext</code> of this
 * <code>ScriptEngine</code>
 * </li>
 * </ul>
 * <br><br>
 * A <code>SimpleScriptContext</code> returned by this method is used to implement eval methods
 * using the abstract <code>eval(Reader,Bindings)</code> and <code>eval(String,Bindings)</code>
 * versions.

 * @param nn Bindings to use for the <code>ENGINE_SCOPE</code>
 * @return The <code>SimpleScriptContext</code>
