Method Detail

exec

public List<JsExpr> exec(SoyNode node)

Description copied from interface: NodeVisitor

Executes the function defined by this visitor.

Specified by:

exec in interface NodeVisitor<SoyNode,List<JsExpr>>

Overrides:

exec in class AbstractNodeVisitor<SoyNode,List<JsExpr>>

Parameters:

node - The node to execute the function on.

execOnChildren

public List<JsExpr> execOnChildren(SoyNode.ParentSoyNode<?> node)

Executes this visitor on the children of the given node, without visiting the given node itself.

visitTemplateNode

protected void visitTemplateNode(TemplateNode node)

Overrides:

visitTemplateNode in class AbstractSoyNodeVisitor<List<JsExpr>>

visitRawTextNode

protected void visitRawTextNode(RawTextNode node)

Example:

   I'm feeling lucky!
 

generates

   'I\'m feeling lucky!'
 

Overrides:

visitRawTextNode in class AbstractSoyNodeVisitor<List<JsExpr>>

visitMsgPlaceholderNode

protected void visitMsgPlaceholderNode(MsgPlaceholderNode node)

Overrides:

visitMsgPlaceholderNode in class AbstractSoyNodeVisitor<List<JsExpr>>

visitGoogMsgRefNode

protected void visitGoogMsgRefNode(GoogMsgRefNode node)

Example:

   MSG_UNNAMED_42
 

Overrides:

visitGoogMsgRefNode in class AbstractSoyNodeVisitor<List<JsExpr>>

visitMsgHtmlTagNode

protected void visitMsgHtmlTagNode(MsgHtmlTagNode node)

Example: <a href="{$url}"> might generate '<a href="' + opt_data.url + '">'

Overrides:

visitMsgHtmlTagNode in class AbstractSoyNodeVisitor<List<JsExpr>>

visitPrintNode

protected void visitPrintNode(PrintNode node)

Example:

   {$boo.foo}
   {$goo.moo + 5}

Overrides:

visitXidNode in class AbstractSoyNodeVisitor<List<JsExpr>>

visitCssNode

protected void visitCssNode(CssNode node)

Note: We would only see a CssNode if the css-handling scheme is BACKEND_SPECIFIC. Example:

might generate

   goog.getCssName('selected-option')
   goog.getCssName(opt_data.foo, 'bar')
 

Overrides:

visitCssNode in class AbstractSoyNodeVisitor<List<JsExpr>>

visitIfNode
