- * Synthesize a text event.
- *
- * The text event's information, this has |composition| and |caret|
- * members.  |composition| has |string| and |clauses| members. |clauses|
- * must be array object.  Each object has |length| and |attr|.
- * And |caret| has |start| and |length|.  See the following tree image.
- *
- *     ev
- *      +-- composition
- *      |     +-- string
- *      |     +-- clauses[]
- *      |           +-- length
- *      |           +-- attr
- *      +-- caret
- *            +-- start
- *            +-- length
- *
- * Set the composition string to |composition.string|.  Set its clauses
- * information to the |clauses| array.
- *
- * When it's composing, set the each clauses' length
- * to the |composition.clauses[n].length|.  The sum
- * of the all length values must be same as the length of
- * |composition.string|. Set nsIDOMWindowUtils.COMPOSITION_ATTR_* to the
- * |composition.clauses[n].attr|.
- *
- * When it's not composing, set 0 to the |composition.clauses[0].length|
- * and |composition.clauses[0].attr|.
- *
- * Set caret position to the |caret.start|. Its offset from the start of
- * the composition string.  Set caret length to |caret.length|.  If it's
- * larger than 0, it should be wide caret.  However, current nsEditor
- * doesn't support wide caret, therefore, you should always set 0 now.
- *
- * @param {Object.<string, ?>} ev
- *     The text event's information,
- * @param {Window=} window
- *     Window object.  Defaults to the current window.
