<h1>Resources Injection</h1>
<div class="sect1">
<h2 id="overview">Overview</h2>
<div class="sectionbody">
<div class="paragraph">
<p>Ignite supports the dependency injection of pre-defined Ignite resources, and supports field-based as well as method-based
injection. Resources with proper annotations will be injected into the corresponding task, job, closure, or SPI before it is initialized.</p>
</div>
</div>
</div>
<div class="sect1">
<h2 id="field-based-and-method-based-injection">Field-Based and Method-Based Injection</h2>
<div class="sectionbody">
<div class="paragraph">
<p>You can inject resources by annotating either a field or a method. When you annotate a field, Ignite simply sets the
value of the field at injection time (disregarding an access modifier of the field). If you annotate a method with
resource annotation, it should accept an input parameter of the type corresponding to an injected resource. If it does,
then the method is invoked at injection time with the appropriate resource passed as an input argument.</p>
