[antlr-interest] I get a note when i compile my grammer

[atif azad]

Dear All

When I compile my grammer and then use the command

Javac *.java to compile the java classes I get the following message


javac  *.java

Note: Sparc2Parser.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.

Then I run with Xlink option to get the following details

javac -Xlint *.java

Sparc2Parser.java:49: warning: [unchecked] unchecked call to put(K,V) as a 
member of the raw type java.util.HashMap
        super.put(attrName, value);
                 ^
Sparc2Parser.java:53: warning: [unchecked] unchecked call to put(K,V) as a 
member of the raw type java.util.HashMap
        super.put(attrName, new Integer(value));
                 ^
Sparc2Parser.java:47: warning: [serial] serializable class 
Sparc2Parser.STAttrMap has no definition of serialVersionUID
    public static class STAttrMap extends HashMap {
                  ^
Sparc2Parser.java:77: warning: [unchecked] unchecked call to push(E) as a 
member of the raw type java.util.Stack
        program_stack.push(new program_scope());




I think this is my portion of the grammer which causes this


grammar Sparc2;
options {

output=template;

}

@header {
import org.antlr.stringtemplate.*;
}

program

scope {
  List globals;
  List functions;
}
@init {
  $program::globals = new ArrayList();
  $program::functions = new ArrayList();
}
    : instructions+


-> program(globals={$program::globals},functions={$program::functions})
    ;



Can any body please help in this regard how to remove this.

Kind Regards

Azad , Atif
