See Also:

Type.distanceTo(org.apache.xalan.xsltc.compiler.util.Type)

translateTo

public void translateTo(ClassGenerator classGen,
                        MethodGenerator methodGen,
                        Type type)

Translates an integer into an object of internal type type.

Overrides:

translateTo in class Type

See Also:

Type.translateTo(org.apache.xalan.xsltc.compiler.util.ClassGenerator, org.apache.xalan.xsltc.compiler.util.MethodGenerator, org.apache.xalan.xsltc.compiler.util.Type)

translateTo

                        MethodGenerator methodGen,
                        RealType type)

Expects an integer on the stack and pushes a real.

See Also:

Type.translateTo(org.apache.xalan.xsltc.compiler.util.ClassGenerator, org.apache.xalan.xsltc.compiler.util.MethodGenerator, org.apache.xalan.xsltc.compiler.util.Type)
