Detailed Description

template<typename T>
class geos::ReferenceWrapper< T >

Template Parameters

Type	that is wrapped

This class manages a pointer to the templated type, but provides a reference-like interface, thus negating the requirement to dereference the object. The primary use for this is for nested arrays that hold pointers at the last level, but allows for reference-like usage. For instance, consider a collection of object that you would like to refer to thought an array of pointers.

array1d< ReferenceWrapper< array1d< double > > > arr;

where the array::operator[] exists. The ReferenceWrapper allows

arr[index1][index2]

note: this is really only useful for heavy array that hold their own data. For light arrays that hold pointers to their data, then this is unnecessary as a copy of the array does not trigger a deep copy.

Template Parameters

T_RHS	type of the rhs
U	dummy template parameter to enable SFINAE stuff

Parameters

[in] rhs value to be copied

Returns: *this

Calls m_ref->operator=() to allow for any type on the rhs if m_ref->operator=() has a valid overload for T_RHS.
