Example 83 with IErlElement

use of org.erlide.engine.model.IErlElement in project erlide_eclipse by erlang.

the class ErlModel method create.

/**
 * Returns the Erlang element corresponding to the given resource, or
 * <code>null</code> if unable to associate the given resource with a Erlang element.
 * <p>
 * The resource must be one of:
 * <ul>
 * <li>a project - the element returned is the corresponding
 * <code>IErlProject</code></li>
 * <li>a <code>.erl</code> file - the element returned is the corresponding
 * <code>IErlModule</code></li>
 * <li>a folder - the element returned is the corresponding
 * <code>IErlFolder</code></li>
 * <li>the workspace root resource - the element returned is the
 * <code>IErlModel</code></li>
 * </ul>
 * <p>
 * Creating a Erlang element has the side effect of creating and opening all of the
 * element's parents if they are not yet open.
 *
 * @param resource
