function xautoload_ClassFinder_Helper_Map::registerNamespacePlugin in X Autoload 7.2

Register a plugin for a namespace or prefix.

Parameters

string $first_part: First part of the path generated from the class name.

xautoload_Plugin_Interface $plugin: The plugin.

File

lib/ClassFinder/Helper/Map.php, line 88

Class

xautoload_ClassFinder_Helper_Map

Helper class for the class finder. This is not part of ClassFinder, because we want to use the same logic for namespaces (PSR-0) and prefixes (PEAR).

Code

function registerNamespacePlugin($first_part, $plugin) {
  if (!isset($plugin)) {
    throw new Exception("Second argument cannot be NULL.");
  }
  elseif (!is_a($plugin, 'xautoload_Plugin_Interface')) {
    throw new Exception("Second argument must implement xautoload_Plugin_Interface.");
  }
  if (!isset($this->nsPlugins[$first_part])) {
    $id = $this->lastPluginIds[$first_part] = 1;
  }
  else {
    $id = ++$this->lastPluginIds[$first_part];
  }
  $this->nsPlugins[$first_part][$id] = $plugin;
  if (method_exists($plugin, 'setKillswitch')) {

    // Give the plugin a red button to unregister or replace itself.
    $plugin
      ->setKillswitch($plugin, $first_part, $id);
  }
  return $id;
}
