Return the iterator range of elements equal to key.

Synopsis

Declared in <bdlc_flathashmap.h>

template<class LOOKUP_KEY>
bsl::pair<iterator, iterator>
equal_range(LOOKUP_KEY const& key)
requires BloombergLP::bslmf::IsTransparentPredicate<HASH, LOOKUP_KEY>::value
         && BloombergLP::bslmf::IsTransparentPredicate<EQUAL,LOOKUP_KEY>::value;

Description

Return a pair of iterators defining the sequence of modifiable elements in this map having a key equivalent to the specified key, where the first iterator is positioned at the start of the sequence and the second iterator is positioned one past the end of the sequence. If this map contains no elements having a key equivalent to key, then the two returned iterators will have the same value. Note that since a map maintains unique keys, the range will contain at most one element.

Return Value

pair of iterators delimiting the equal range

Parameters

Name

Description
