System::ArraySegment class

ArraySegment class

Represents a segment of the one-dimensional array. Objects of this class should only be allocated using System::MakeObject() function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into System::SmartPtr pointer and use this pointer to pass it to functions as argument.

template<typename T>class ArraySegment : public System::Object
ParameterDescription
TThe type of the array segment elements.

Methods

MethodDescription
ArraySegment(System::ArrayPtr<T>)
ArraySegment(System::ArrayPtr<T>, int32_t, int32_t)
ArraySegment()
Equals(System::SharedPtr<Object>) override
Equals(ArraySegment<T>)
get_Array()
get_Count()
get_Offset()
GetHashCode() const overrideAnalog of C# Object.GetHashCode() method. Enables hashing of custom objects.

Remarks

#include <system/array_segment.h>
#include <system/smart_ptr.h>

using namespace System;

void Print(const SmartPtr<ArraySegment<String>> &segment)
{
  for (auto i = segment->get_Offset(); i < segment->get_Offset() + segment->get_Count(); i++)
  {
    std::cout << segment->get_Array()[i] << ' ';
  }
  std::cout << std::endl;
}

int main()
{
  // Create and fill the array.
  auto array = System::MakeObject<Array<String>>(3);
  array[0] = u"First";
  array[1] = u"Second";
  array[2] = u"Third";

  // Create the array segment that contains the entire array.
  auto fullArray = MakeObject<ArraySegment<String>>(array);

  // Print the array segment items.
  Print(fullArray);

  // Create the array segment.
  auto segment = MakeObject<ArraySegment<String>>(array, 1, 2);

  // Print the array segment items.
  Print(segment);

  return 0;
}
/*
This code example produces the following output:
First Second Third
Second Third
