/**
 * This function can be used by GemFire clients and peers to commit an existing transaction. A
 * {@link TransactionId} corresponding to the transaction to be committed must be provided as an
 * argument while invoking this function.<br />
 *
 * This function should execute only on one server. If the transaction is not hosted on the server
 * where the function is invoked then this function decides to invoke a nested
 * {@link NestedTransactionFunction} which executes on the member where transaction is hosted.<br />
 *
 * This function returns a single Boolean as result, whose value is <code>Boolean.TRUE</code> if the
 * transaction committed successfully otherwise the return value is
 * <code>Boolean.FALSE</code>.<br />
 *
 * To execute this function, it is recommended to use the {@link Execution} obtained by using
 * TransactionFunctionService. <br />
 *
 * To summarize, this function should be used as follows:
 *
 * <pre>
 * Execution exe = TransactionFunctionService.onTransaction(txId);
 * List l = (List) exe.execute(commitFunction).getResult();
 * Boolean result = (Boolean) l.get(0);
 * </pre>
 *
 * This function is <b>not</b> registered on the cache servers by default, and it is the user's
 * responsibility to register this function. see {@link FunctionService#registerFunction(Function)}
 *
 * @since GemFire 6.6.1
