Constructors Summary
public IOJavaFileWriter(File file) Creates a new instance of IOJavaFileWriter. param file The file object which will be used at save time. _file = file;

Methods Summary
public void	addClass(com.sun.jdo.spi.persistence.utility.generator.JavaClassWriter classWriter) Adds a class to this source file. param classWriter The definition of the class. if (classWriter != null) _classes.add(classWriter);
public void	addImport(java.lang.String importName, java.lang.String[] comments) Adds an import statement for this source file. param importName Name of the class or package (including the *) to be imported. This string should not contain "import" or the ; param comments The comments shown just above the import statement. The comments are passed as an array so the line separators can be added by the implementation. Note that not all implementations will choose to make use of this comment. final FormattedWriter writerHelper = new FormattedWriter(); writerHelper.writeComments(comments); if (importName != null && importName.length() > 0) writerHelper.writeln("import " + importName + ';"); // NOI18N _importStatements.add(writerHelper.toString());
protected static final java.util.ResourceBundle	getMessages() return I18N message handler for this element return _messages;
public void	save() Saves the file by writing out the source contents to whatever file (or alternate representation) was specified (usually by the constructor of the implementation class. throws IOException If the file cannot be saved. if (_file != null) { final File directory = _file.getParentFile(); final FileWriter fileWriter; if (directory != null) { if (!directory.exists() && !directory.mkdirs()) { throw new IOException(I18NHelper.getMessage(getMessages(), "utility.unable_create_destination_directory", // NOI18N directory.getPath())); } } fileWriter = new FileWriter(_file); try { fileWriter.write(toString()); } finally { fileWriter.close(); } }
public void	setPackage(java.lang.String packageName, java.lang.String[] comments) Sets the package for this file. Note that the package name format must be package style (that is - it can contain . but not / or $). param packageName The name of the package for this source file. param comments The comments shown just above the package statement. The comments are passed as an array so the line separators can be added by the implementation. Note that not all implementations will choose to make use of this comment. final FormattedWriter writerHelper = new FormattedWriter(); writerHelper.writeComments(comments); if (packageName != null && packageName.length() > 0) { writerHelper.writeln("package " + packageName + ';"); // NOI18N writerHelper.writeln(); } _packageBlock = writerHelper.toString();
public java.lang.String	toString() Returns a string representation of this object. return The string representation of the generated file. final FormattedWriter writerHelper = new FormattedWriter(); // package block writerHelper.writeln(); if (_packageBlock != null) writerHelper.write(_packageBlock); writerHelper.writeList(_importStatements); // imports writerHelper.writeList(_classes); // classes return writerHelper.toString();
