Synopsis

Classes

struct _BracketMatcher
Matches a character range (bracket expression)
class _Compiler
Builds an NFA from an input iterator range.
struct _Default_ranged_hash
Default ranged hash function H. In principle it should be a function object composed from objects of type H1 and H2 such that h(k, N) = h2(h1(k), N), but that would mean making extra copies of h1 and h2. So instead we'll just use a tag to tell class template hashtable to do that composition.
struct _Equality
struct _Equality< _Key, _Value, _Alloc, _ExtractKey, _Equal, _Hash, _RangeHash, _Unused, _RehashPolicy, _Traits, false >
unordered_multiset and unordered_multimap specializations.
struct _Equality< _Key, _Value, _Alloc, _ExtractKey, _Equal, _Hash, _RangeHash, _Unused, _RehashPolicy, _Traits, true >
unordered_map and unordered_set specializations.
class _Executor
Takes a regex and an input string and does the matching.
struct _Hash_code_base
struct _Hash_node
struct _Hash_node_base
struct _Hash_node_code_cache
struct _Hash_node_code_cache< true >
struct _Hash_node_value_base
struct _Hashtable_alloc
struct _Hashtable_base
struct _Hashtable_ebo_helper
struct _Hashtable_ebo_helper< _Nm, _Tp, false >
Specialization not using EBO.
struct _Hashtable_ebo_helper< _Nm, _Tp, true >
Specialization using EBO.
struct _Hashtable_traits
struct _Insert
struct _Insert< _Key, _Value, _Alloc, _ExtractKey, _Equal, _Hash, _RangeHash, _Unused, _RehashPolicy, _Traits, false >
Specialization.
struct _Insert< _Key, _Value, _Alloc, _ExtractKey, _Equal, _Hash, _RangeHash, _Unused, _RehashPolicy, _Traits, true >
Specialization.
struct _Insert_base
struct _List_node_base
Common part of a node in the list.
struct _List_node_header
The list node header.
struct _Local_const_iterator
local const_iterators
struct _Local_iterator
local iterators
struct _Local_iterator_base
struct _Local_iterator_base< _Key, _Value, _ExtractKey, _Hash, _RangeHash, _Unused, true >
Partial specialization used when nodes contain a cached hash code.
struct _Map_base
struct _Map_base< _Key, _Pair, _Alloc, _Select1st, _Equal, _Hash, _RangeHash, _Unused, _RehashPolicy, _Traits, false >
Partial specialization, __unique_keys set to false.
struct _Map_base< _Key, _Pair, _Alloc, _Select1st, _Equal, _Hash, _RangeHash, _Unused, _RehashPolicy, _Traits, true >
Partial specialization, __unique_keys set to true.
struct _Mask_range_hashing
Range hashing function assuming that second arg is a power of 2.
struct _Mod_range_hashing
Default range hashing function: use division to fold a large number into the range [0, N).
struct _Node_const_iterator
Node const_iterators, used to iterate through all the hashtable.
struct _Node_iterator
Node iterators, used to iterate through all the hashtable.
struct _Node_iterator_base
Base class for node iterators.
struct _Power2_rehash_policy
Rehash policy providing power of 2 bucket numbers. Avoids modulo operations.
struct _Prime_rehash_policy
Default value for rehash policy. Bucket size is (usually) the smallest prime that keeps the load factor small enough.
struct _Quoted_string
Struct for delimited strings.
struct _Rehash_base
struct _Rehash_base< _Key, _Value, _Alloc, _ExtractKey, _Equal, _Hash, _RangeHash, _Unused, _RehashPolicy, _Traits, false_type >
Specialization when rehash policy doesn't provide load factor management.
struct _Rehash_base< _Key, _Value, _Alloc, _ExtractKey, _Equal, _Hash, _RangeHash, _Unused, _RehashPolicy, _Traits, true_type >
Specialization when rehash policy provide load factor management.
class _Scanner
Scans an input range for regex tokens.
class _StateSeq
Describes a sequence of one or more _State, its current start and end(s). This structure contains fragments of an NFA during construction.
