  • Methodendetails

    • isPrimitiveOrBoxedPrimitive

      public boolean isPrimitiveOrBoxedPrimitive()
      Beschreibung aus Klasse kopiert: ExpressionType
      Returns whether the type is a primitive type or a boxed primitive type.
      Angegeben von:
      isPrimitiveOrBoxedPrimitive in Klasse ExpressionType
      Gibt zurück:
      true if it is a primitive type and false otherwise

    • isAssignable

      public int isAssignable(Transpiler transpiler, ExpressionType other)
      Beschreibung aus Klasse kopiert: ExpressionType
      Checks whether a values of the specified type other is assignable to a variable of this type or not. If a value of that type is not assignable a negative value is returned. A zero or positive value is returned if it is assignable. A zero value indicates a perfect type match and greater values indicate a less perfect type match, e.g. unboxing of a primitive type is required or the a value of a sub class type should be assigned.
      Angegeben von:
      isAssignable in Klasse ExpressionType
      Parameter:
      transpiler - the transpiler object used for utility methods
      other - the other type
      Gibt zurück:
      a postive value or zero if the type is assignable and a negative value if not.
