    • getReflectClass

      public Class getReflectClass()
      Description copied from class: Type
      Get the java.lang.Class object for the representation type.
      Overrides:
      getReflectClass in class Type
    • getImplementationType

      public Type getImplementationType()
      Description copied from class: Type
      Return Java-level implementation type. The type used to implement types not natively understood by the JVM or the Java language. Usually, the identity function. However, a language might handle union types or template types or type expressions calculated at run time. In that case return the type used at the Java level, and known at compile time.

    • emitCoerceFromObject

      public void emitCoerceFromObject(CodeAttr code)
      Description copied from class: Type
      Compile code to coerce/convert from Object to this type.
      Overrides:
      emitCoerceFromObject in class Type
    • emitCoerceToObject

      public void emitCoerceToObject(CodeAttr code)
      Description copied from class: Type
      Compile code to convert a object of this type on the stack to Object.
      Overrides:
      emitCoerceToObject in class Type
    • emitTestIf

      public void emitTestIf(Variable incoming, Declaration decl, Compilation comp)
      Description copied from interface: TypeValue
      Emit code for if (incoming instanceof this_type) decl = incoming .... This method is designed for typeswitch applications, where this call is the first part of a conditional, so it must be followed by calls to emitElse and emitFi.
      Specified by:
      emitTestIf in interface TypeValue
      Parameters:
      incoming - Contains the value we are testing to see if it has the type of this. If null, use top-of-stack. May not be null if decl is non-null.
      decl - If non-null, assign value after coercion to Declaration.
      comp - The compilation state.
    • convertValue

      public Expression convertValue(Expression value)
      Description copied from interface: TypeValue
      Return converted expression or null.
      Specified by:
      convertValue in interface TypeValue
    • isInstance

      public boolean isInstance(Object obj)
      Overrides:
      isInstance in class Type
    • emitIsInstance

      public void emitIsInstance(Variable incoming, Compilation comp, Target target)
      Description copied from interface: TypeValue
      Emit code for incoming instanceof this_type. The implementation can use InstanceOf .emitIsInstance which is a conveniece method that calls emitTestIf.
      Specified by:
      emitIsInstance in interface TypeValue
      Parameters:
      incoming - Contains the value we are testing to see if it has the the type of 'this'. If null, use top-of-stack.
      comp - The compilation state.
      target - Where to leave the result.
    • toString

      public Object cast(Object value)
    • coerceFromObject

      public Object coerceFromObject(Object obj)
      Description copied from class: Type
      Convert an object to a value of this Type. The result is actually of the implementation type, boxed as appropriate, so it is suitable for standard reflective operations, like the arguments to Field#set or Method#invoke. Throw a ClassCastException when this is not possible.
      Specified by:
      coerceFromObject in class Type
    • compare

      public int compare(Type other)
      Description copied from class: Type
      Return a numeric code showing "subtype" relationship: 1: if other is a pure subtype of this; 0: if has the same values; -1: if this is a pure subtype of other; -2: if they have values in common but neither is a subtype of the other; -3: if the types have no values in common. "Same values" is rather loose; by "A is a subtype of B" we mean that all instance of A can be "widened" to B. More formally, A.compare(B) returns: 1: all B values can be converted to A without a coercion failure (i.e. a ClassCastException or overflow or major loss of information), but not vice versa. 0: all A values can be converted to B without a coercion failure and vice versa; -1: all A values can be converted to B without a coercion failure but not vice versa; -2: there are (potentially) some A values that can be converted to B, and some B values can be converted to A; -3: there are no A values that can be converted to B, and neither are there any B values that can be converted to A.

      public Procedure getConstructor()
      Description copied from interface: TypeValue
      Get the constructor function for this type. Returns null if there is no contructor function. Also returns null if this extends ClassType or ArrayType and standard Java constructors (<init> methods) should be used.
