Method Detail

exec

public List<PyExpr> exec(SoyNode node)

Description copied from interface: NodeVisitor

Executes the function defined by this visitor.

Specified by:

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

Overrides:

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

Parameters:

node - The node to execute the function on.

visitRawTextNode

protected void visitRawTextNode(RawTextNode node)

Example:

   I'm feeling lucky!
 

generates

   'I\'m feeling lucky!'
 

Overrides:

visitRawTextNode in class AbstractSoyNodeVisitor<List<PyExpr>>

visitPrintNode

protected void visitPrintNode(PrintNode node)

Visiting a print node accomplishes 3 basic tasks. It loads data, it performs any operations needed, and it executes the appropriate print directives.

TODO(dcphillips): Add support for local variables once LetNode are supported.

Example:

   {$boo |changeNewlineToBr}
   {$goo + 5}
 

might generate

   sanitize.change_newline_to_br(data.get('boo'))
   data.get('goo') + 5
 

Overrides:

visitPrintNode in class AbstractSoyNodeVisitor<List<PyExpr>>

visitMsgFallbackGroupNode

protected void visitMsgFallbackGroupNode(MsgFallbackGroupNode node)

Overrides:

visitMsgFallbackGroupNode in class AbstractSoyNodeVisitor<List<PyExpr>>

visitIfNode

protected void visitIfNode(IfNode node)

If all the children are computable as expressions, the IfNode can be written as a ternary conditional expression.

Overrides:

visitIfNode in class AbstractSoyNodeVisitor<List<PyExpr>>

visitIfCondNode

protected void visitIfCondNode(IfCondNode node)

Overrides:

visitIfCondNode in class AbstractSoyNodeVisitor<List<PyExpr>>

visitIfElseNode

protected void visitIfElseNode(IfElseNode node)

Overrides:

visitIfElseNode in class AbstractSoyNodeVisitor<List<PyExpr>>

visitCallNode

protected void visitCallNode(CallNode node)

Overrides:

visitCallNode in class AbstractSoyNodeVisitor<List<PyExpr>>

visitCallParamContentNode

protected void visitCallParamContentNode(CallParamContentNode node)

Overrides:

visitCallParamContentNode in class AbstractSoyNodeVisitor<List<PyExpr>>
