  genCallCodeUtils - Instance of GenCallCodeUtils to use.

  isComputableAsJsExprsVisitor - The IsComputableAsJsExprsVisitor to use.

Method Detail

• exec

  public Void exec(SoyNode node)

  Description copied from interface: NodeVisitor
  Executes the function defined by this visitor.

  Specified by:

  exec in interface NodeVisitor<SoyNode,Void>

  Overrides:

  exec in class AbstractNodeVisitor<SoyNode,Void>

  Parameters:

  node - The node to execute the function on.

• generateMsgGroupVariable

  public String generateMsgGroupVariable(MsgFallbackGroupNode node)

  Generates Javascript statements that declare a translated variable, returning the variable name for the caller to output (as an expression). MsgFallbackGroupNodes can only appear in let blocks, which seems like unnecesary overhead since this already generates a perfectly usable variable. However, this design makes incremental DOM codegen, which needs to apply complex transforms on the translated variable, much simpler. Example:

     {msg desc="Link to help content."}Learn more{/msg}
     {msg desc="Tells user how to access a product." hidden="true"}
       Click <a href="}{$url}">here</a> to access {$productName}.
     {/msg}
   

  might generate

     /** @desc Link to help content. */
     var MSG_UNNAMED_9 = goog.getMsg('Learn more');
     var msg_s9 = MSG_UNNAMED_9;
     /** @desc Tells user how to access a product.
      *  @hidden */
     var MSG_UNNAMED_10 = goog.getMsg(
         'Click {$startLink}here{$endLink} to access {$productName}.',
         {startLink: '<a href="' + opt_data.url + '">',
          endLink: '</a>',
          productName: opt_data.productName});
   

  and return "MSG_UNNAMED_10".

• genGoogMsgPlaceholderExpr

  protected JsExpr genGoogMsgPlaceholderExpr(MsgPlaceholderNode msgPhNode)

  Generates the JS expr for a given placeholder.

  Parameters:

  msgPhNode - The placeholder to generate the JS expr for.

  Returns:

  The JS expr for the given placeholder.

• visitMsgHtmlTagNode

  protected void visitMsgHtmlTagNode(MsgHtmlTagNode node)

  Example:

     <a href="http://www.google.com/search?hl=en
       {for $i in range(3)}
         &param{$i}={$i}
       {/for}
     ">
   might generate
   

  var htmlTag84 = (new soy.StringBuilder()).append('<a href="'); for (var i80 = 1; i80 < 3; i80++) { htmlTag84.append('&param', i80, '=', i80); } htmlTag84.append('">');

  Overrides:

  visitMsgHtmlTagNode in class AbstractSoyNodeVisitor<Void>

• visitSoyNode

  protected void visitSoyNode(SoyNode node)

  Overrides:

  visitSoyNode in class AbstractSoyNodeVisitor<Void>

  Parameters:

  node - the visited node.
