Example 61 with ScriptEngine

use of javax.script.ScriptEngine in project sling by apache.

the class SlingScriptAdapterFactory method getAdapter.

Example 62 with ScriptEngine

use of javax.script.ScriptEngine in project sling by apache.

the class SlingScriptAdapterFactory method getMimeType.

// ---------- MimeTypeProvider
/**
     * Returns the first MIME type entry of the supported MIME types of a
     * ScriptEngineFactory which is registered for the extension of the given
     * name. If no ScriptEngineFactory is registered for the given extension or
     * the registered ScriptEngineFactory is not registered for a MIME type,
     * this method returns <code>null</code>.
     *
     * @param name The name whose extension is to be mapped to a MIME type. The
     *            extension is the string after the last dot in the name. If the
     *            name contains no dot, the entire name is considered the
     *            extension.
