Page 120, second code snippet:

void foo(const Any& arg)
{
    const Type& t = arg.getValueType();
    if (t == cppu::UnoType< XReference >::get())
    {
        Reference<XReference> myref = *reinterpret_cast<const Reference<XReference>*>(arg.getValue());
        ...
    }
}

Page 137, entire section "Mapping of Type":

The UNO type type is mapped to com::sun::star::uno::Type. It holds the name of a type and the com.sun.star.uno.TypeClass. The type allows you to obtain a com::sun::star::uno::TypeDescription that contains all the information defined in the IDL. For a given UNO type, a corresponding com::sun::star::uno::Type instance can be obtained through the cppu::UnoType class template:

// Get the UNO type long:
com::sun::star::uno::Type longType = cppu::UnoType< sal_Int32 >::get();

// Get the UNO type char:
com::sun::star::uno::Type charTpye = cppu::UnoType< cppu::UnoCharType >::get();

// Get the UNO type string:
com::sun::star::uno::Type stringType = cppu::UnoType< rtl::OUString >::get();

// Get the UNO interface type com.sun.star.container.XEnumeration:
com::sun::star::uno::Type enumerationType =
    cppu::UnoType< com::sun::star::container::XEnumeration >::get();

Some C++ types that represent UNO types cannot be used as C++ template arguments, or ambiguously represent more than one UNO type, so there are special C++ types cppu::UnoVoidType, cppu::UnoUnsignedShortType, cppu::UnoCharType, and cppu::UnoSequenceType that can be used as arguments for cppu::UnoType in those cases.

The overloaded getCppuType function was an older mechanism to obtain com::sun::star::uno::Type instances. It is deprecated now (certain uses of getCppuType in template code would not work as intended), and cppu::UnoType should be used instead.

Page 138, third code snippet:

Any foo()
{
    sal_Int32 i = 2;
    if( ... )
        i = ...;
    return Any( &i, cppu::UnoType< sal_Int32 >::get() );
}

Page 139, first paragraph after the bulleted list:

On some platforms, the C++ typedef types sal_uInt16 (representing the UNO type unsigned short) and sal_Unicode (representing the UNO type char) are synonyms for the same fundamental C++ type. This could lead to problems when either of those types is used as a type argument of a polymorphic struct type. The chosen solution is to generally forbid the (deprecated) UNO types unsigned short, unsigned long, and unsigned hyper as type arguments of polymorphic struct types.

Page 194, second code snippet:

Any automObject;
// pVariant is a VARIANT* and contains the value that is going to be converted
automObject.setValue((void*) &pVariant, cppu::UnoType< sal_uInt32 >::get());
