| /** |
| * Provides interfaces that enable the development of input methods that can be |
| * used with any Java runtime environment. Input methods are software components |
| * that let the user enter text in ways other than simple typing on a keyboard. |
| * They are commonly used to enter Japanese, Chinese, or Korean - languages |
| * using thousands of different characters - on keyboards with far fewer keys. |
| * However, this package also allows the development of input methods for other |
| * languages and the use of entirely different input mechanisms, such as |
| * handwriting recognition. |
| * |
| * <h2><a id="Packaging"></a>Packaging Input Methods</h2> |
| * Input methods can be made available by adding them to the application's class |
| * path. The main JAR file of an input method must contain the file: |
| * <pre> |
| * META-INF/services/java.awt.im.spi.InputMethodDescriptor |
| * </pre> |
| * The file should contain a list of fully-qualified class names, one per line, |
| * of classes implementing the {@code java.awt.im.spi.InputMethodDescriptor} |
| * interface. Space and tab characters surrounding each name, as well as blank |
| * lines, are ignored. The comment character is {@code '#'} |
| * ({@code \u005Cu0023}); on each line all characters following the first |
| * comment character are ignored. The file must be encoded in UTF-8. |
| * <p> |
| * For example, if the fully-qualified name of the class that implements |
| * {@code java.awt.im.spi.InputMethodDesciptor} for the <em>Foo</em> input |
| * method is {@code com.sun.ime.FooInputMethodDescriptor}, the file |
| * {@code META-INF/services/java.awt.im.spi.InputMethodDescriptor} |
| * contains a line: |
| * <pre> |
| * com.sun.ime.FooInputMethodDescriptor |
| * </pre> |
| * The input method must also provide at least two classes: one class |
| * implementing the {@code java.awt.im.spi.InputMethodDescriptor} interface, one |
| * class implementing the {@code java.awt.im.spi.InputMethod} interface. The |
| * input method should separate the implementations for these interfaces, so |
| * that loading of the class implementing {@code InputMethod} can be deferred |
| * until actually needed. |
| * |
| * <h2><a id="Loading"></a>Loading Input Methods</h2> |
| * The input method framework will usually defer loading of input method |
| * classes until they are absolutely needed. It loads only the |
| * {@code InputMethodDescriptor} implementations during AWT initialization. It |
| * loads an {@code InputMethod} implementation when the input method has been |
| * selected. |
| * |
| * <h2><a id="PeeredComponents"></a>Java Input Methods and Peered Text |
| * Components</h2> |
| * The Java input method framework intends to support all combinations of input |
| * methods (host input methods and Java input methods) and components (peered |
| * and lightweight). However, because of limitations in the underlying platform, |
| * it may not always be possible to enable the communication between Java input |
| * methods and peered AWT components. Support for this specific combination is |
| * therefore platform dependent. In Sun's Java SE Runtime Environments, this |
| * combination is supported on Windows, but not on Solaris. |
| * |
