implements <a href="../../../../../org/apache/drill/exec/ops/ExecutorFragmentContext.html" title="interface in org.apache.drill.exec.ops">ExecutorFragmentContext</a></pre>
<div class="block">This is the core Context which implements all the Context interfaces:
<ul>
<li><a href="../../../../../org/apache/drill/exec/ops/FragmentContext.html" title="interface in org.apache.drill.exec.ops"><code>FragmentContext</code></a>: A context provided to non-exchange
operators.</li>
<li><a href="../../../../../org/apache/drill/exec/ops/ExchangeFragmentContext.html" title="interface in org.apache.drill.exec.ops"><code>ExchangeFragmentContext</code></a>: A context provided to exchange
operators.</li>
<li><a href="../../../../../org/apache/drill/exec/ops/RootFragmentContext.html" title="interface in org.apache.drill.exec.ops"><code>RootFragmentContext</code></a>: A context provided to fragment roots.</li>
<li><a href="../../../../../org/apache/drill/exec/ops/ExecutorFragmentContext.html" title="interface in org.apache.drill.exec.ops"><code>ExecutorFragmentContext</code></a>: A context used by the Drillbit.</li>
</ul>
The interfaces above expose resources to varying degrees. They are ordered
from most restrictive (<a href="../../../../../org/apache/drill/exec/ops/FragmentContext.html" title="interface in org.apache.drill.exec.ops"><code>FragmentContext</code></a>) to least restrictive
(<a href="../../../../../org/apache/drill/exec/ops/ExecutorFragmentContext.html" title="interface in org.apache.drill.exec.ops"><code>ExecutorFragmentContext</code></a>).
</p>
<p>
Since <a href="../../../../../org/apache/drill/exec/ops/FragmentContextImpl.html" title="class in org.apache.drill.exec.ops"><code>FragmentContextImpl</code></a> implements all of the interfaces listed
above, the facade pattern is used in order to cast a
<a href="../../../../../org/apache/drill/exec/ops/FragmentContextImpl.html" title="class in org.apache.drill.exec.ops"><code>FragmentContextImpl</code></a> object to the desired interface where-ever it is
needed. The facade pattern is powerful since it allows us to easily create
minimal context objects to be used in unit tests. Without the use of
interfaces and the facade pattern we would have to create a complete
<a href="../../../../../org/apache/drill/exec/ops/FragmentContextImpl.html" title="class in org.apache.drill.exec.ops"><code>FragmentContextImpl</code></a> object to unit test any part of the code that
depends on a context.
</p>
<p>
<b>General guideline:</b> Use the most narrow interface for the task. For
example, "internal" operators don't need visibility to the networking
functionality. Using the narrow interface allows unit testing without using
mocking libraries. Often, the surrounding structure already has exposed the
most narrow interface. If there are opportunities to clean up older code, we
can do so as needed to make testing easier.

particular partition. This allows for the implementation of UDFs to
query against the partition information, without having to read
the actual data contained in the partition. This interface is designed
for UDFs that take only constant inputs, as this interface will only
be useful if we can evaluate the constant UDF at planning time.
Any function defined to use this interface that is not evaluated
at planning time by the constant folding rule will be querying
the storage plugin for meta-data for each record processed.
Be sure to check the query plans to see that this expression has already
been evaluated during planning if you write UDFs against this interface.
See <code>DirectoryExplorers</code> for
example usages of this interface.</div>
