                        MethodGenerator methodGen,
                        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,

                          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

                        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)

                        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)

                        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

                                         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)

                        MethodGenerator methodGen,
                        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)

    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
```
public void translateBox(ClassGenerator classGen,
