### translateTo

    public void translateTo(ClassGenerator classGen,

                            Type type)

  Translates a node-set into an object of internal type `type`. The translation to int is undefined since node-sets are always converted to reals in arithmetic expressions.
  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)`

### translateFrom

    public void translateFrom(ClassGenerator classGen,
                              MethodGenerator methodGen,
                              java.lang.Class clazz)

  Translates an external Java Class into an internal type. Expects the Java object on the stack, pushes the internal type
  Overrides:
    translateFrom in class Type

### translateTo

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

  Translates a node-set into a synthesized boolean. The boolean value of a node-set is "true" if non-empty and "false" otherwise. Notice that the function getFirstNode() is called in translateToDesynthesized().
  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

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

  Translates a node-set into a string. The string value of a node-set is value of its first element.
  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

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

  Expects a node-set on the stack and pushes a real. First the node-set is converted to string, and from string to 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)`

### translateTo

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

  Expects a node-set on the stack and pushes a node.
  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

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

  Subsume node-set into ObjectType.
  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)`

### translateToDesynthesized

    public FlowList translateToDesynthesized(ClassGenerator classGen,
                                             MethodGenerator methodGen,
                                             BooleanType type)

  Translates a node-set into a non-synthesized boolean. It does not push a 0 or a 1 but instead returns branchhandle list to be appended to the false list.
  Overrides:
    translateToDesynthesized in class Type
  See Also:
    `Type.translateToDesynthesized(org.apache.xalan.xsltc.compiler.util.ClassGenerator, org.apache.xalan.xsltc.compiler.util.MethodGenerator, org.apache.xalan.xsltc.compiler.util.Type)`

### translateTo

    public void translateTo(ClassGenerator classGen,

                            ReferenceType type)

  Expects a node-set on the stack and pushes a boxed node-set. Node sets are already boxed so the translation is just a NOP.
  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

  Translates a node-set into the Java type denoted by `clazz`. Expects a node-set on the stack and pushes an object of the appropriate type after coercion.
  Overrides:
    translateTo in class Type

### translateBox

                             MethodGenerator methodGen)
