package go/ast
An Ellipsis node stands for the "..." type in a parameter list or the "..." length in an array type.
Golang go/ast.Ellipsis type, End() and Pos() functions examples
Example 1:
func NodeDescription(n ast.Node) string {
switch n := n.(type) {
case *ast.ArrayType:
return "array type"
case *ast.AssignStmt:
return "assignment"
case *ast.Ellipsis:
return "ellipsis"
...
}
Example 2:
func checkCurrentPosition(node ast.Node) string {
n := node.(*ast.Ellipsis)
endpos := n.End()
pospos := n.Pos()
if pospos != endpos {
return "not yet"
}
}
