Detailed Description

template<template< class, class > class Container, template< class > class Allocator>
class folly::gen::detail::CollectTemplate< Container, Allocator >

CollectTemplate - For collecting values from a source in a collection constructed using the specified template type. Given the type of values produced by the given generator, the collection type will be: Container<Value, Allocator<Value>>

The allocator defaults to std::allocator, so this may be used for the STL containers by simply using operators like 'as<set>', 'as<deque>', 'as<vector>'. 'as', here is the helper method which is the usual means of constructing this operator.

Example:

set<string> uniqueNames = from(names) | as<set>();
