  • canonicalize

    public static final Expression canonicalize(Expression exp)

    Simplifies BeginExp. (In the future, nested BeginExps may be "flattened" as well.)

  • setCompileOptions

    public void setCompileOptions(java.util.Vector options)

  • mustCompile

    protected boolean mustCompile()

    Specified by:

    mustCompile in class Expression

  • apply

    public void apply(CallContext ctx)
     throws java.lang.Throwable

    Description copied from class: Expression
    Evaluate the expression. This is named apply rather than eval so it is compatible with the full-tail-call calling convention, and we can stash an Expression in CallContext's proc field. FIXME - are we making use of this?

    Overrides:

    apply in class Expression

    Throws:

    java.lang.Throwable

  • pushOptions

    public void pushOptions(Compilation comp)

  • popOptions

    public void popOptions(Compilation comp)

  • compile

    public void compile(Compilation comp,
     Target target)

    Specified by:

    compile in class Expression

  • visit

    protected <R,D> R visit(ExpVisitor<R,D> visitor,
     D d)

    Overrides:

    visit in class Expression

  • visitChildren

    protected <R,D> void visitChildren(ExpVisitor<R,D> visitor,
     D d)

    Overrides:

    visitChildren in class Expression

  • print

    Specified by:

  • calculateType
