Class MethodSplitter.Token

java.lang.Object
  harpoon.Analysis.Transformation.MethodSplitter.Token

All Implemented Interfaces:

Serializable

Enclosing class:

MethodSplitter

protected abstract static class MethodSplitter.Token
extends Object
implements Serializable

Subclasses of MethodSplitter refer to "versions" of the underlying method which may be named by creating static instances of this MethodSplitter.Token class. The argument to the constructor specifies a default suffix for the newly-split method's name. Don't forget to extend MethodSplitter.isValidToken() to include your new MethodSplitter.Token subclasses.

A typical subclass of MethodSplitter will include the following code fragment:

  public class FooBlah extends MethodSplitter {
    /** Token for the foo-blah version of a method. */
    public static final Token FOOBLAH = new Token("fooblah") {
      /** This ensures that FOOBLAH is a singleton object. */
      public Object readResolve() { return FOOBLAH; }
    };
    /** Checks the token types handled by this 
     *  MethodSplitter subclass. */
    protected boolean isValidToken(Token which) {
      return which==FOOBLAH || super.isValidToken(which);
    };
  };
