    • hasPrimitiveWideningConversionFrom

      public boolean hasPrimitiveWideningConversionFrom(Type t)
      Return true iff there is a primitive widening conversion from Type t to this type.

      public boolean isAssignmentConvertibleFrom(Type t)
      Return true iff there is an assignment conversion from Type t to this type.

    • isCastingConvertibleFrom

      public boolean isCastingConvertibleFrom(Type t)
      Return true iff there is a casting conversion from Type t to this type.

    • unaryPromotion

      public Type unaryPromotion()
      Return the type that is a unary promotion of this type.

    • binaryPromotion

      Return the type that is the binary promotion of this type and Type t.

    • isMethodInvocationConvertibleFrom

      public boolean isMethodInvocationConvertibleFrom(Type t)
      Return true iff one of the following statements is true:
      1. this.equals( t ) .
      2. There is a widening primitive conversion from Type t to this Type (see JLS 5.1.2).
      3. There is a widening reference conversion from Type t to this Type (see JLS 5.1.4).
      This is similar to Class.isAssignmentCompatibleFrom, but also handles widening primitive conversions. Throws NullPointerException if t == null.
