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
- 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:
  
  toJCType in class 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 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)
- translateTo
  
  public void translateTo(ClassGenerator classGen, 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)
- translateTo
  
  public void translateTo(ClassGenerator classGen, MethodGenerator methodGen, Class clazz)
  
  Translates an internal boolean into an external (Java) boolean.
  
  Overrides:
  
  translateTo in class Type
- translateFrom
  
  public void translateFrom(ClassGenerator classGen, MethodGenerator methodGen, Class clazz)
  
  Translates an external (Java) boolean into internal boolean.
  
  Overrides:
  
  translateFrom in class Type
- translateBox
  
  public void translateBox(ClassGenerator classGen, MethodGenerator methodGen)
  
  Translates an object of this type to its boxed representation.
  
  Overrides:
  
  translateBox in class Type
- translateUnBox
  
  public void translateUnBox(ClassGenerator classGen, MethodGenerator methodGen)
  
  Translates an object of this type to its unboxed representation.
  
  Overrides:
  
  translateUnBox in class Type
- LOAD
  
  public org.apache.bcel.generic.Instruction LOAD(int slot)
  
  Overrides:
  
  LOAD in class Type

  public org.apache.bcel.generic.BranchInstruction GT(boolean tozero)
  
  Overrides:
  
  GT in class Type
- GE
  
  public org.apache.bcel.generic.BranchInstruction GE(boolean tozero)
  
  Overrides:
  
  GE in class Type
