<p>
<a class="link" href="DeeTransaction.html" title="DeeTransaction"><span class="type">DeeTransaction</span></a> is a self contained change set related to some particular
<span class="type">DeeModel</span> called the <span class="emphasis"><em>target model</em></span>.
</p>
<p>
The transaction instance itself implements the <span class="type">DeeModel</span> interface in a way
that overlays the target model. In database terms the target model has
isolation level READ_COMMITTED. Meaning that the target model is not modified
until you call <a class="link" href="DeeTransaction.html#dee-transaction-commit" title="dee_transaction_commit ()"><code class="function">dee_transaction_commit()</code></a>.
</p>
<p>
To flush the changes to the target model call <a class="link" href="DeeTransaction.html#dee-transaction-commit" title="dee_transaction_commit ()"><code class="function">dee_transaction_commit()</code></a>.
After committing the transaction will become invalid and must be freed with
<code class="function">g_object_unref()</code>. It is a programming error to try and access a transaction
that has been committed with the sole exception of calling
<a class="link" href="DeeTransaction.html#dee-transaction-is-committed" title="dee_transaction_is_committed ()"><code class="function">dee_transaction_is_committed()</code></a>.
