    toString in class Type
  - identicalTo
```
public boolean identicalTo(Type other)
```
    Description copied from class: Type
    
    Returns true if this and other are identical types.
    
    Specified by:
    
    identicalTo in class Type
  - toSignature
```
public java.lang.String toSignature()
```
    Description copied from class: Type
    
    Returns the signature of an internal type's external representation.
    
    Specified by:
    
    toSignature in class Type
  - isSimple
```
public boolean isSimple()
```
    Description copied from class: Type
    
    Returns true if this type is a simple type. Redefined in NumberType, BooleanType and StringType.
    
    Overrides:
    
    isSimple in class Type
  - toJCType
```
public org.apache.bcel.generic.Type toJCType()
```
    Specified by:

  - translateTo
```
public void translateTo(ClassGenerator classGen,
                        MethodGenerator methodGen,
                        Type type)
```
    Translates a real into an object of internal type type. The translation to int is undefined since booleans 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)
  - translateTo
```
public void translateTo(ClassGenerator classGen,
                        MethodGenerator methodGen,
                        StringType type)
```
    Expects a boolean on the stack and pushes a string. If the value on the stack is zero, then the string 'false' is pushed. Otherwise, the string 'true' is pushed.
    
    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 boolean on the stack and pushes a real. The value "true" is converted to 1.0 and the value "false" to 0.0.
    
    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,
                        ReferenceType type)
```
    Expects a boolean on the stack and pushes a boxed boolean. Boxed booleans are represented by an instance of java.lang.Boolean.
    
    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) boolean into internal boolean.
    
    Overrides:
    
    translateFrom in class Type
  - translateBox
```
public void translateBox(ClassGenerator classGen,
                         MethodGenerator methodGen)
