Member Function Documentation

begin()

constexpr std::size_t hi::v1::jsonpath::slice::begin ( std::size_t size ) const

inlineconstexprnoexcept

Get the start offset.

Parameters

size	The size of the container.

Returns

The start offset of the slice.

end()

constexpr std::size_t hi::v1::jsonpath::slice::end ( std::size_t size ) const

inlineconstexprnoexcept

Get the one-step beyond last offset.

This will calculate the last offset of an integer number of steps starting from begin(). This allows the end() to be equality compared inside a for loop, even when the step is negative.

Parameters

size	The size of the container.

Returns

The one-step beyond last offset of the slice.
