function translation_node_view in Drupal 7

Implements hook_node_view().

Displays translation links with language names if this node is part of a translation set. If no language provider is enabled, "fall back" to simple links built through the result of translation_node_get_translations().

Manages content translations.

Code

function translation_node_view($node, $view_mode) {

  // translation links to display.

    // switch links which need to be taken into account while generating the
    // content translation links. As custom language switch links are available

    // configurable language type in core, we use it as default. Contributed
    // modules can change this behavior by setting the system variable below.
