<div class="block">Returns a new <a href="../../../../../../org/apache/beam/sdk/extensions/jackson/ParseJsons.ParseJsonsWithFailures.html" title="class in org.apache.beam.sdk.extensions.jackson"><code>ParseJsons.ParseJsonsWithFailures</code></a> transform that catches exceptions raised while
parsing elements, passing the raised exception instance and the input element being processed
through the default exception handler <code>DefaultExceptionAsMapHandler</code> and emitting the
result to a failure collection.
<p>See <code>DefaultExceptionAsMapHandler</code> for more details about default handler behavior.
<p>See <a href="../../../../../../org/apache/beam/sdk/transforms/WithFailures.html" title="class in org.apache.beam.sdk.transforms"><code>WithFailures</code></a> documentation for usage patterns of the returned <code>WithFailures.Result</code>.
<p>Example usage:
<pre><code>
WithFailures.Result&lt;PCollection&lt;MyPojo&gt;, KV&lt;String, Map&lt;String, String&gt;&gt;&gt; result =
json.apply(
ParseJsons.of(MyPojo.class)
.exceptionsVia());
PCollection&lt;MyPojo&gt; output = result.output(); // valid POJOs
PCollection&lt;KV&lt;String, Map&lt;String, String&gt;&gt;&gt; failures = result.failures();
