Detailed Description

template<class K, class T, class H = RWTHash<K>, class EQ = std::equal_to<K>, class A = std::allocator<K*>>
class RWTPtrOrderedHashMap< K, T, H, EQ, A >

RWTPtrOrderedHashMap maintains a collection of K key pointers, each with an associated item that is a pointer of type T. These std::pair<K* const, T*> pairs are stored according to a hash object of type H. RWTPtrOrderedHashMap preserves key insertion order.

Class A is an allocator of objects of class T. For more information about using custom allocators, please see the Essential Tools Module User's Guide.

H must provide a const function that takes a single argument convertible to type K and returns a value of type size_t.

Note
Any two keys that are equivalent must hash to the same value.

Key equality is determined by an equality function of type EQ, which takes two arguments convertible to type K and returns a value of type bool.

Note
Any two keys that are equivalent are disallowed for this container.

This class does not allow duplicate keys, that is, keys that are equivalent to a key already in the collection. Use the class RWTPtrOrderedHashMultiMap if you need multiple keys to be equivalent to each other. Equality is based on the comparison object, not on operator==().

The value type must have operator==() defined. This requirement is imposed by the C++ Standard Library.

Synopsis
#include <rw/tools/tpordhmap.h>
See also

Class RWTPtrOrderedHashMultiMap offers the same interface to a pointer-based collection that accepts multiple keys that compare equal to each other.

Class rw_orderedhashmap<K*,T*,hasher,key_equal,A> is the C++ Standard Library-style collection that serves as the underlying implementation for this class.

mapped_type& RWTPtrOrderedHashMap< K, T, H, EQ, A >::operator[] ( key_type  key)
inline

Looks up key and returns a reference to its associated item. If the key is not in the dictionary, it is added with an associated uninitialized pointer of type mapped_type. Because of this, if there is a possibility that a key will not be in the dictionary, this operator should be used only as an lvalue.

inline

Removes the first association a in self such that the expression ((*fn)(a,d)) is true, and returns its key. Returns rwnil if there is no such association. Client data may be passed through parameter d.

template<class K, class T, class H = RWTHash<K>, class EQ = std::equal_to<K>, class A = std::allocator<K*>>
key_type RWTPtrOrderedHashMap< K, T, H, EQ, A >::remove ( const K *  key)
inline

Removes the first association with key j in self that compares equal to *key, and returns j. Returns rwnil if there is no such association.

template<class K , class T , class H , class EQ , class A >
RWTPtrOrderedHashMap< K, T, H, EQ, A >::size_type RWTPtrOrderedHashMap< K, T, H, EQ, A >::removeAll ( bool(*)(value_type, void *)  fn,
void *  d 
)

Removes all associations a in self such that the expression ((*fn)(a,d)) is true. Returns the number of associations removed. Client data may be passed through parameter d.

template<class K, class T, class H = RWTHash<K>, class EQ = std::equal_to<K>, class A = std::allocator<K*>>
size_type RWTPtrOrderedHashMap< K, T, H, EQ, A >::removeAll ( const K *  key)
inline

Removes all associations with key j in self that compare equal to *key. Returns the number of associations removed.

template<class K, class T, class H = RWTHash<K>, class EQ = std::equal_to<K>, class A = std::allocator<K*>>
key_type RWTPtrOrderedHashMap< K, T, H, EQ, A >::removeKeyAndValue ( const K *  key,
mapped_type retVal 
)
inline

If find(key) succeeds, erases the pair associated with key, places the value part in retVal, and returns key. Otherwise, returns rwnil.

template<class K, class T, class H = RWTHash<K>, class EQ = std::equal_to<K>, class A = std::allocator<K*>>
void RWTPtrOrderedHashMap< K, T, H, EQ, A >::resize ( size_type  sz)
inline

Changes the capacity of self by creating a new hashmap with a capacity of sz. Then copies every association in self into the new container and finally swaps the internal representation of the new container with the internal representation of self.

template<class K, class T, class H = RWTHash<K>, class EQ = std::equal_to<K>, class A = std::allocator<K*>>
container_type& RWTPtrOrderedHashMap< K, T, H, EQ, A >::std ( )
inline

Returns a reference to the underlying C++ Standard Library collection that serves as the implementation for self.

template<class K, class T, class H = RWTHash<K>, class EQ = std::equal_to<K>, class A = std::allocator<K*>>
const container_type& RWTPtrOrderedHashMap< K, T, H, EQ, A >::std ( ) const
inline

Returns a reference to the underlying C++ Standard Library collection that serves as the implementation for self.

template<class K, class T, class H = RWTHash<K>, class EQ = std::equal_to<K>, class A = std::allocator<K*>>
void RWTPtrOrderedHashMap< K, T, H, EQ, A >::swap ( RWTPtrOrderedHashMap< K, T, H, EQ, A > &  rhs)
inline

Swaps the data owned by self with the data owned by rhs.

Looks at the next object on the input stream strm and either creates a new collection off the heap and sets p to point to it, or sets p to point to a previously read instance. If a collection is created off the heap, the application is responsible for deleting it.
