Detailed Description

struct _Nfa

A collection of all states making up an NFA.

An NFA is a 4-tuple M = (K, S, s, F), where K is a finite set of states, S is the alphabet of the NFA, s is the initial state, F is a set of final (accepting) states.

This NFA class is templated on S, a type that will hold values of the underlying alphabet (without regard to semantics of that alphabet). The other elements of the tuple are generated during construction of the NFA and are available through accessor member functions.

Assigns a given value to a vector.

Parameters:

__n Number of elements to be assigned.
__val Value to be assigned.

This function fills a vector with __n copies of the given value. Note that the assignment completely changes the vector and that the resulting vector's size is the same as the number of elements assigned. Old data may be lost.

Definition at line 479 of file stl_vector.h.

void std::vector< _State , std::allocator<_State > >::assign (_InputIterator__first, _InputIterator__last) [inline], [inherited]

Assigns a range to a vector.

Parameters:

__first An input iterator.
__last An input iterator.

This function fills a vector with copies of the elements in the range [__first,__last).

Note that the assignment completely changes the vector and that the resulting vector's size is the same as the number of elements assigned. Old data may be lost.

Definition at line 498 of file stl_vector.h.

void std::vector< _State , std::allocator<_State > >::assign (initializer_list< value_type >__l) [inline], [inherited]

Assigns an initializer list to a vector.

Parameters:

__l An initializer_list.

This function fills a vector with copies of the elements in the initializer list __l.

Note that the assignment completely changes the vector and that the resulting vector's size is the same as the number of elements assigned. Old data may be lost.

Remove element at given position.

Parameters:

__position Iterator pointing to element to be erased.

Returns:

An iterator pointing to the next element (or end()).

This function will erase the element at the given position and thus shorten the vector by one.

Note This operation could be expensive and if it is frequently used the user should consider using std::list. The user is also cautioned that this function only erases the element, and that if the element is itself a pointer, the pointed-to memory is not touched in any way. Managing the pointer is the user's responsibility.

iterator std::vector< _State , std::allocator<_State > >::erase (iterator__first, iterator__last) [inherited]

Remove a range of elements.

Parameters:

__first Iterator pointing to the first element to be erased.
__last Iterator pointing to one past the last element to be erased.

Returns:

An iterator pointing to the element pointed to by __last prior to erasing (or end()).

This function will erase the elements in the range [__first,__last) and shorten the vector accordingly.

Note This operation could be expensive and if it is frequently used the user should consider using std::list. The user is also cautioned that this function only erases the elements, and that if the elements themselves are pointers, the pointed-to memory is not touched in any way. Managing the pointer is the user's responsibility.

reference std::vector< _State , std::allocator<_State > >::operator[] (size_type__n) [inline], [inherited]

Subscript access to the data contained in the vector.

Parameters:

__n The index of the element for which data should be accessed.

Returns:

Read/write reference to data.

This operator allows for easy, array-style, data access. Note that data access with this operator is unchecked and out_of_range lookups are not defined. (For checked lookups see at().)

Definition at line 770 of file stl_vector.h.

const_reference std::vector< _State , std::allocator<_State > >::operator[] (size_type__n) const [inline], [inherited]

Subscript access to the data contained in the vector.

Parameters:

__n The index of the element for which data should be accessed.

Returns:

Read-only (constant) reference to data.

This operator allows for easy, array-style, data access. Note that data access with this operator is unchecked and out_of_range lookups are not defined. (For checked lookups see at().)

Definition at line 785 of file stl_vector.h.

void std::vector< _State , std::allocator<_State > >::pop_back () [inline], [inherited]

Removes last element. This is a typical stack operation. It shrinks the vector by one.

Note that no data is returned, and if the last element's data is needed, it should be retrieved before pop_back() is called.

Definition at line 937 of file stl_vector.h.

void std::vector< _State , std::allocator<_State > >::push_back (const value_type &__x) [inline], [inherited]

Add data to the end of the vector.

Parameters:

__x Data to be added.

This is a typical stack operation. The function creates an element at the end of the vector and assigns the given data to it. Due to the nature of a vector this operation can be done in constant time if the vector has preallocated space available.

References std::vector< _Tp, _Alloc >::begin().

void std::vector< _State , std::allocator<_State > >::reserve (size_type__n) [inherited]

Attempt to preallocate enough memory for specified number of elements.

Parameters:

__n Number of elements required.

Exceptions:

std::length_error If n exceeds max_size().

This function attempts to reserve enough memory for the vector to hold the specified number of elements. If the number requested is more than max_size(), length_error is thrown.

The advantage of this function is that if optimal code is a necessity and the user can determine the number of elements that will be required, the user can reserve the memory in advance, and thus prevent a possible reallocation of memory and copying of vector data.

void std::vector< _State , std::allocator<_State > >::resize (size_type__new_size) [inline], [inherited]

Resizes the vector to the specified number of elements.

Parameters:

__new_size Number of elements the vector should contain.

This function will resize the vector to the specified number of elements. If the number is smaller than the vector's current size the vector is truncated, otherwise default constructed elements are appended.

Definition at line 664 of file stl_vector.h.

References std::vector< _Tp, _Alloc >::size().

void std::vector< _State , std::allocator<_State > >::resize (size_type__new_size, const value_type &__x) [inline], [inherited]

Resizes the vector to the specified number of elements.

Parameters:

__new_size Number of elements the vector should contain.
__x Data with which new elements should be populated.

This function will resize the vector to the specified number of elements. If the number is smaller than the vector's current size the vector is truncated, otherwise the vector is extended and new elements are populated with given data.

Member Data Documentation

std::vector< _State , std::allocator<_State > >::__pad0__ [explicit], [inherited]

Creates a vector with default constructed elements.

Parameters:

__n The number of elements to initially create.
__a An allocator.

This constructor fills the vector with __n default constructed elements.

Definition at line 270 of file stl_vector.h.

std::vector< _State , std::allocator<_State > >::void [inherited]

Swaps data with another vector.

Parameters:

__x A vector of the same element and allocator types.

This exchanges the elements between two vectors in constant time. (Three pointers, so it should be quite fast.) Note that the global std::swap() function is specialized such that std::swap(v1,v2) will feed to this function.
