Detailed Description

template<typename T>
struct tgen::sequence< T >::instance

Sequence instance.

Instance of a sequence.

It can be deterministically operated upon (see Generator Instance Operations for random operations) and printed through std::cout.

Constructor & Destructor Documentation

instance()

template<typename T>

tgen::sequence< T >::instance::instance ( const std::vector< T > & vec )

inline

Creates a sequence instance from a std::vector.

Parameters

vec	The std::vector representing the instance.

Examples

// Creates and prints an instance from a std::vector.
std::vector<int> v = {1, 2, 3};
tgen::sequence<int>::instance inst(v);
std::cout << inst << std::endl; // Prints "1 2 3".
 
// Also works with std::initializer_list<T>.
inst = {5, 4};
std::cout << inst << std::endl; // Prints "5 4".

Member Function Documentation

operator+()

template<typename T>

instance tgen::sequence< T >::instance::operator+ ( const instance & rhs )

inline

Concatenates two instances.

Parameters

rhs	The right-hand side.

Returns

The concatenation.

Complexity

Linear.

Examples

// Concatenates and prints two instances.
tgen::sequence<int> s = tgen::sequence<int>(5, 1, 5).distinct();
std::cout << s.gen() + s.gen() << std::endl;

Definition at line 1293 of file tgen.h.

operator[]()

template<typename T>

T & tgen::sequence< T >::instance::operator[] ( int idx )

inline

Accesses the value at some position of the instance.

Parameters

idx	Index to be accessed.

Returns

The value at index idx.

Examples

// Changes and prints a position of an instance.
tgen::sequence<int>::instance inst = {1, 2, 3};
++inst[1];
std::cout << inst[1] << std::endl; // Prints "3".

Definition at line 1259 of file tgen.h.

reverse()

template<typename T>

instance & tgen::sequence< T >::instance::reverse ( )

inline

Reverses the instance.

Complexity

O(n).

Examples

// Reverses and prints an instance.
tgen::sequence<int>::instance inst = {3, 1, 2};
std::cout << inst.reverse() << std::endl; // Prints "2 1 3".

Definition at line 1279 of file tgen.h.

separator()

template<typename T>

instance & tgen::sequence< T >::instance::separator ( char sep )

inline

Sets separator for printing.

Complexity

O(1).

Examples

// Prints an instance, separated by commas.
tgen::sequence<int>::instance inst = {3, 1, 2};
std::cout << inst.separator(',') << std::endl; // Prints "3,1,2".

Definition at line 1286 of file tgen.h.

size()

template<typename T>

int tgen::sequence< T >::instance::size ( ) const

inline

Returns the size of the sequence instance.

Returns

The size (number of elements) of the sequence instance.

Examples

// Prints the size of an instance.
tgen::sequence<int>::instance inst = {1, 2, 3};
std::cout << inst.size() << std::endl; // Prints "3".

Definition at line 1256 of file tgen.h.

sort()

template<typename T>

instance & tgen::sequence< T >::instance::sort ( )

inline

Sorts the instance in non-decreasing order.

Complexity

O(n log n).

Examples

// Sorts and prints an instance.
tgen::sequence<int>::instance inst = {3, 1, 2};
std::cout << inst.sort() << std::endl; // Prints "1 2 3".

Definition at line 1272 of file tgen.h.

to_std()

template<typename T>

std::vector< T > tgen::sequence< T >::instance::to_std ( ) const

inline

Converts the instance to a std::vector.

Returns

A std::vector representing the instance.

Examples

// Convoluted way to reverse a vector.
std::vector<int> v = {3, 1, 2};
v = tgen::sequence<int>::instance(v).reverse().to_std();
// v = {2, 1, 3}.

Friends And Related Symbol Documentation

operator<<

template<typename T>

std::ostream & operator<< ( std::ostream & out, const instance & inst )

friend

Prints the instance to a std::ostream.

The values are printed with one space as a separator, and with no end of line.

Examples

// Prints an instance.
std::cout << tgen::sequence<int>::instance({3, 1, 2}) << std::endl; // Prints "3 1 2".
