package go/ast
All declaration nodes implement the Decl interface.
Golang go/ast.Decl type usage examples
Example 1:
func ParseDecl(x string) (ast.Decl, error) {
file, err := parser.ParseFile(token.NewFileSet(), "", "package p\n//line :1\n"+x+"\n", 0)
if err != nil {
return nil, err
}
return file.Decls[0], nil
}
Example 2:
func (check *Checker) declStmt(decl ast.Decl) {
pkg := check.pkg
switch d := decl.(type) {
case *ast.BadDecl:
// ignore
case *ast.GenDecl:
// do something
...
}
