Method Details
- toString
  
  public String toString()
  
  Description copied from class: Type
  
  Returns a string representation of this type.
  
  Specified by:
  
  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 String toSignature()
  
  Description copied from class: Type
  
  Returns the signature of an internal type's external representation.
  
  Specified by:
  
  toSignature in class Type
- toJCType
  
  public org.apache.bcel.generic.Type toJCType()
  
  Specified by:
  
  toJCType in class Type
- distanceTo
  
  public int distanceTo(Type type)
  
  Description copied from class: Type
  
  Returns the distance between two types. This measure is used to select overloaded functions/operators. This method is typically redefined by the subclasses.
  Overrides:
  
  distanceTo in class Type
  
  See Also:
  
  Type.distanceTo(org.apache.xalan.xsltc.compiler.util.Type)
- 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 reals are never converted to ints.
  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 real on the stack and pushes its string value by calling Double.toString(double d).
  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, BooleanType type)
  
  Expects a real on the stack and pushes a 0 if that number is 0.0 and a 1 otherwise.
  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, IntType type)
  
  Expects a real on the stack and pushes a truncated integer value
  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 real 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. A NaN must be converted to "false".
  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, MethodGenerator methodGen, ReferenceType type)
  
  Expects a double on the stack and pushes a boxed double. Boxed double are represented by an instance of java.lang.Double.
  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, Class clazz)
  
  Translates a real into the Java type denoted by clazz. Expects a real on the stack and pushes a number of the appropriate type after coercion.
  
  Overrides:
  
  translateTo in class Type
- translateFrom
  
  public void translateFrom(ClassGenerator classGen, MethodGenerator methodGen, Class clazz)
  
  Translates an external (primitive) Java type into a real. Expects a java object on the stack and pushes a real (i.e., a double).
  
  Overrides:
  
  translateFrom in class Type
- translateBox
  
  public void translateBox(ClassGenerator classGen, MethodGenerator methodGen)
  
  Translates an object of this type to its boxed representation.
  
  Overrides:
