示例1: Visit
func (v *evalVisitor) Visit(root ast.Node) (interface{}, ast.Type, error) {
// Run the actual visitor pattern
root.Accept(v.visit)
// Get our result and clear out everything else
var result *ast.LiteralNode
if v.Stack.Len() > 0 {
result = v.Stack.Pop().(*ast.LiteralNode)
} else {
result = new(ast.LiteralNode)
}
resultErr := v.err
if resultErr == errExitUnknown {
// This means the return value is unknown and we used the error
// as an early exit mechanism. Reset since the value on the stack
// should be the unknown value.
resultErr = nil
}
// Clear everything else so we aren't just dangling
v.Stack.Reset()
v.err = nil
t, err := result.Type(v.Scope)
if err != nil {
return nil, ast.TypeInvalid, err
}
return result.Value, t, resultErr
