Example 86 with IWorkspaceRoot

use of org.eclipse.core.resources.IWorkspaceRoot in project yamcs-studio by yamcs.

the class FileUtil method writeTextFile.

/**
 * Write a text file.
 *
 * @param filePath
 *            path of the file. It can be an absolute path or a relative path to the OPI that contains the specified
 *            widget. If it is an absolute path, it can be either<br>
 *            a workspace path such as <code>/BOY Examples/Scripts/myfile.xml</code><br>
 *            a local file system path such as <code>C:\myfile.xml</code><br>
 *            or an URL path such as <code>http://mysite.com/myfile.xml</code>.
 * @param inWorkspace
 *            true if the file path is a workspace file path. Otherwise, it will be recognized as a local file
 *            system file.
 * @param widget
 *            a widget in the OPI, which is used to provide relative path reference. It can be null if the path is
 *            an absolute path.
 * @param text
 *            the text to be written to the file.
 * @param append
 *            true if the text should be appended to the end of the file.
 * @throws Exception
 *             if error happens.
