Header <alps/alea.h>

includes all headers in the alps/alea directory

Header <alps/cctype.h>

A safe version of the standard cctype header.

Some cctype headers do not undefine harmful macros, so undefine them here.

Header <alps/expression.h>

includes all headers in the alps/expression directory

Header <alps/factory.h>

object factories

This header contains an implementation of an object factory

namespace alps {
template<typename KEY, typename BASE> class factory;
}

Header <alps/functional.h>

extensions to the standard functional header

This header contains mathematical function objects not present in the standard or boost libraries.

namespace alps {
    template<typename T> struct conj_mult;

    template<typename T> struct conj_mult<std::complex< T >>;
}

Header <alps/lambda.hpp> 

namespace boost {
    namespace lambda {
        template<typename Act, typename T> 
            struct plain_return_type_2<arithmetic_action< Act >, std::valarray< T >, std::valarray< T >>;

Header <alps/lattice.h>

includes all headers in the alps/lattice directory

Header <alps/model.h>

includes all headers in the alps/model directory

Header <alps/multi_array.hpp>

extensions to boost::multi_array

This header defines some I/O extensions to boost::multi_array and fixes a problem with gcc-3.1 when alps::multi_array and alps::serialization are used together

access namespace alps {

    // ALPS de-serialization support for boost::multi_array. 
    template<typename T, std::size_t NumDims, typename Allocator> 
        alps::IDump & 
        operator>>(alps::IDump & dump, 
           boost::multi_array< T, NumDims, Allocator > & x);

    // ALPS serialization support for boost::multi_array. 
    template<typename T, std::size_t NumDims, typename Allocator> 
        alps::ODump & 
        operator<<(alps::ODump & dump, 
           const boost::multi_array< T, NumDims, Allocator > & x);
}

// writes a two-dimensional boost::multi_array to an output stream 
template<typename T, typename Allocator> 
    std::ostream & 
    operator<<(std::ostream & out, 
         const boost::multi_array< T, 2, Allocator > & x);

// writes a four-dimensional boost::multi_array to an output stream 
template<typename T, typename Allocator> 
    std::ostream & 
    operator<<(std::ostream & out, 
         const boost::multi_array< T, 4, Allocator > & x);

Header <alps/osiris.h>

includes all headers in the alps/osiris directory

Header <alps/plot.h>

classes to create plots in XML format

This header contains classes to create plots in XML format, compatible with the ALPS XML schema for plot files on the http://xml.comp-phys.org/ web page

namespace alps {
    namespace plot {
        template<typename C> class Point;
        template<typename C> class Set;
        template<typename C> class Plot;

        enum SetType;

        // write a plot to an XML file following the ALPS XML schema for plots on http://xml.comp-phys.org/
        template<typename C> 
            oxstream & operator<<(oxstream & out, const Plot< C > & p);
        template<typename C> 
            oxstream & operator<<(oxstream & o, const Set< C > & S);
    }
}

Header <alps/random.h>

includes all headers in the alps/random directory

Header <alps/stringvalue.h>

implements a string class that can easily be assigned to and converted to any type

namespace alps {
    template<typename StringBase> class lexical_cast_string;

    typedef lexical_cast_string StringValue;  // StringValue is now implemented using lexical_cast_string. 
}

Header <alps/xml.h>

includes all headers in the alps/parser directory
